SUBJECT CONTENT

Summary File 1 (SF 1) contains the data compiled from the questions asked of all people and about 

every housing unit. Population items include sex, age, race, Hispanic or Latino origin, household 

relationship, household type, household size, family type, family size, and group quarters. Housing 

items include occupancy status, vacancy status, and tenure (whether a housing unit is owner-occupied or 

renter-occupied). 

There are 177 population tables (identified with a ‘‘P’’) and 58 housing tables (identified with an ‘‘H’’) shown 

down to the block level; 82 population tables (identified with a ‘‘PCT’’) and 4 housing tables (identified with 

an “HCT”) shown down to the census tract level; and 10 population tables (identified with a “PCO”) shown 

down to the county level, for a total of 331 tables. The SF 1 Urban/Rural Update added 2 PCT tables, 

increasing the total number to 333 tables. There are 14 population tables and 4 housing tables shown 

down to the block level and 5 population tables shown down to the census tract level that are repeated by 

the major race and Hispanic or Latino groups.2

SF 1 includes population and housing characteristics for the total population, population totals for an 

extensive list of race (American Indian and Alaska Native tribes, Asian, and Native Hawaiian and Other 

Pacific Islander) and Hispanic or Latino groups, and population and housing characteristics for a limited 

list of race and Hispanic or Latino groups. Population and housing items may be cross-tabulated. Selected 

aggregates and medians also are provided. A complete listing of subjects in this file is found in the 

“Subject Locator” chapter.

1 This includes the District of Columbia and Puerto Rico.

2 These selected tables are repeated by the following: White alone; Black or African American alone; American Indian and Alaska 

Native alone; Asian alone; Native Hawaiian and Other Pacific Islander alone; Some Other Race alone; Two or More Races; Hispanic or 

Latino; and White alone, not Hispanic or Latino. One table, PCT12, is also repeated by Black or African American alone, not Hispanic or 

Latino; American Indian and Alaska Native alone, not Hispanic or Latino; Asian alone, not Hispanic or Latino; Native Hawaiian and Other 

Pacific Islander alone, not Hispanic or Latino; Some Other Race alone, not Hispanic or Latino; and Two or More Races, not Hispanic or 

Latino.

U.S. Census Bureau, 2010 Census Summary File 1

GEOGRAPHIC CONTENT

Summary File 1 (SF 1) is released as individual files for each of the 50 states, the District of Columbia, and 

Puerto Rico, and for the United States. The tables (matrices) are identical for all files, but the geographic 

coverage differs. SF 1 for states was released from June–August 2011. The national update file, without 

urban and rural components, was released in October 2011. The Urban/Rural Update of SF 1 also was 

released as individual files for the 50 states, the District of Columbia, Puerto Rico, and for the United 

States in September 2012. 

This abstract lists the most frequently accessed geographic levels. The “Summary Level Sequence Chart” 

chapter outlines the hierarchical and inventory geographic summaries in their entirety. Two summary level 

sequence charts are provided: for the state files and the national update file. Additional summary level 

sequence charts are added for the SF 1 Urban/Rural update.

State Files

SF 1 for states, the District of Columbia, and Puerto Rico provides data for these areas and their subareas 

in hierarchical sequence down to the block level (P and H tables), the census tract level (PCT and HCT 

tables), or the county level (PCO tables), depending on the detail shown in the table. The file structure 

includes, but is not limited to the following geographic levels:

State3

 County4

 County subdivision5

 Place (or place part)

 Census tract

 Block group

 Block

American Indian and Alaska Native area and Hawaiian home land

SF 1 for states also has inventory (complete) summaries for the following geographic levels:

Place

Metropolitan statistical area (or state portion)

Micropolitan statistical area (or state portion)

Urban area (Urban/Rural Update file only)

Congressional district (111th Congress)

State legislative district

School district

Consolidated city

ZIP Code® tabulation area (ZCTATM) (or state portion)

3 This includes states, the District of Columbia, and Puerto Rico.

4 Parish in Louisiana; borough, census area, city and borough, or municipality in Alaska; and municipio in Puerto Rico. In Maryland, 

Missouri, Nevada, and Virginia, one or more cities are independent of counties and are treated as statistical equivalents of counties. The 

entire District of Columbia, which has no counties, is treated as a county equivalent. 5 In Puerto Rico, some county subdivisions (barrios-pueblos and barrios) are divided into subminor civil divisions (subbarrios).

INTRODUCTION

This chapter serves as a guide for data users to both the file and the technical documentation. Novice 

users trying to understand how to use the documentation and the file should read this chapter first. 

DATA FORMAT AND ACCESS TOOLS

Flat ASCII files by state and for the nation are available for download via File Transfer Protocol (FTP) from 

American FactFinder on the U.S. Census Bureau’s Web site, <www.census.gov>.

Users can utilize their standard software packages to manipulate the data, which can be easily imported. 

The geographic header record data are presented in fixed-length ASCII format, and the data file is in 

comma-separated ASCII format.

The DVD product contains an updated version of the Census 2000 Data Engine software that can 

aggregate user-defined areas, allows for multiple geographic selections, and creates customized variables 

and reports. Both the State files and National file will be included as a single DVD product. The DVD 

provides no data on urban and rural areas. The software can export files in several formats, including 

databases and spreadsheets. Files can also be exported in compatible formats for use with most GIS 

applications. 

Geographic Hierarchy Primer

The smallest component for all census geography is the block. Figure 2-3 at the end of this chapter 

provides an example of the various geographic hierarchies used, building from the block. Take some 

time to review this chart to become familiar with the different hierarchies. Begin reading the schematic 

from the bottom at the blocks entry. By following the lines, you can see the hierarchy very quickly. For 

example, follow blocks to block groups to census tracts to counties. This path indicates that census

tracts and their sublevels in the hierarchy are uniquely identified within a county and do not cross county 

boundaries. Follow blocks to the school district hierarchy. This path tells you that school districts can cross 

jurisdictional boundaries but do not cross state lines. Figure 2-4 at the end of this chapter presents similar 

information for the American Indian area/Alaska Native area/Hawaiian home land hierarchy. Again, read 

the schematic from the bottom, beginning with the lowest level of geography, i.e., census blocks. 

GEOGRAPHIC HEADER RECORD

The geographic header record, Figure 2-5 at the end of this chapter, defines each field and provides its 

data dictionary reference name, field size, starting position, and data type. In addition, the presence or 

absence of an “X” in each summary level column is a guide to the presence or absence of geographic 

information for that particular summary level. For example, on the column for summary level 040, we 

see “X” for the first 10 fields, indicating that there will be information for those fields. In the county field, 

there is no “X,” indicating that there is no information for county in summary level 040, since 040 is the 

summary level for state.

New ANSI Codes

The geographic header record includes, for the first time, space reserved to accommodate the transition 

from the Federal Information Processing Standards (FIPS) 55 Code Series to the American National 

Standards Institute (ANSI) Code Series for the identification of selected geographic entities. Each of nine 

fields has eight character spaces reserved for an eight-digit Geographic Names Information System (GNIS) 

identifier code that has been adopted as part of a new national standard. The GNIS is the nation’s official 

geographic names repository database and has been designated by the U.S. Board on Geographic Names 

as the official source of geographic names for use by the federal government and its contractors. Federal 

agencies are expected to adopt the GNIS ID as a standard code for public and federal data exchange. The 

fields identified in the geographic header record are:

Field length Field name

8 State (ANSI)

8 County (ANSI)

8 County Subdivision (ANSI)

8 Place (ANSI)

8 Consolidated City (ANSI)

8 American Indian Area/Alaska Native Area/Hawaiian Home 

 Land (ANSI)

8 American Indian Tribal Subdivision (ANSI)

8 Alaska Native Regional Corporation (ANSI)

8 Subminor Civil Division (ANSI)

The GNIS identifier for states, counties, and equivalent areas are supplemental codes that do not replace 

the federal standard two-digit state and three-digit county codes also appearing in the header. The Census 

Bureau will continue to maintain and use in its unique geographic identifiers the existing five-digit codes 

for place, county subdivision, consolidated city, Alaska Native Regional Corporation, and subminor civil 

division and will assign and issue codes for new entities to meet customer needs, although these codes 

are not “official” or part of the new ANSI standards. The Census Bureau also will continue to maintain the 

existing four-digit codes for American Indian area/Alaska Native area/Hawaiian home land and three-digit 

codes for American Indian tribal subdivision.

U.S. Census Bureau, 2010 Census Summary File 1

Summary Level Sequence Chart

The summary level sequence chart (Chapter 4) identifies each geographic level and provides the code that 

is in the SUMLEV field. The last geographic area type listed in the sequence identifies the geography of the 

summary level; the prior codes simply identify the geographic hierarchy. 

•	 140 State-County-Census Tract

•	 144 State-County-Census Tract-American Indian area/Alaska Native area/Hawaiian home land

For summary level 140, the record contains data for a census tract, within a county, within a state. Census 

tracts are uniquely numbered within a county and do not cross county boundaries. Since counties do not 

cross state boundaries, this is a simple application. Thus, summary level 140 provides data for a complete 

census tract.

In summary level 144, the geography is more complex. The key is to work backward through the 

hierarchy. Thus, summary level 144 is a record for the portion of an American Indian Area (or an Alaska 

Native area or a Hawaiian home land) within a specific census tract within a specific county within a state.

When reading the summary level sequence chart, it is important to recognize that hyphens (-) separate 

the individual hierarchies, while slashes separate different types of geography (such as place/remainder) 

within the same hierarchy.

DATA STRUCTURE AND SEGMENTATION

The data in Summary File 1 and other 2010 Census summary files are segmented. This is done to facilitate 

exporting into spreadsheet or database software. The data and the corresponding geographic information 

for an individual state is known as the file set. Because of the large size of the tables, the initial SF 1 file set is 

broken into 48 files: a geographic header record file and 47 table files. The SF 1 Urban/Rural Update file set is 

broken into 49 files: a geographic header record and 48 table files. Figure 2-2 provides the file/table details.

When using Figure 2-2, you must take into consideration that the first 5 fields of the data file contain 

identification information (FILEID, STUSAB, CHARITER, CIFSN, and LOGRECNO) which makes some segments 

have more than 255 fields. These segments are shown in bold. Some manipulation of the files will be 

required for software with a field limit of 255.

It is easiest to think of the file set as a logical file. However, this logical file consists of 48 physical files: 

the geographic header record file and file01 through file47 (or file48). This file design is comparable to 

that used in Census 2000. 

A unique logical record number (LOGRECNO in the geographic header) is assigned to all files for a specific 

geographic entity. This is done so all records for that specific entity can be linked together across files. 

Besides the logical record number, other identifying fields also are carried over from the geographic header 

file to the table file. These are file identification (FILEID), state/U.S. abbreviation (STUSAB), characteristic 

iteration (CHARITER), and characteristic iteration file sequence number (CIFSN). See Figure 2-1 on the next 

page for an example.

The geographic header record is standard across all electronic data products from the 2010 Census. 

Some header fields that appear in both files (geographic header and file01), are not used. For example, 

CHARITER field will be used in the 2010 Census Summary File 2 but is always coded as 000 in the 

2010 Census Summary File 1.

Note to Users of Microsoft Access

Due to the FieldSize property limitations within Microsoft Access, modifications to field types are required 

when importing the geographic header record file and file01 through file47 (or file48):

•	 All fields classified as numeric (N) should be imported as long integers.

•	 AREALAND and AREAWATR should be imported as text.

Failure to make these changes may result in missing data upon import.

GENERAL INFORMATION

The Subject Locator is an index designed to quickly identify the tables (matrices) in the summary file. This 

index is arranged in alphabetical order by the name of a subject. Under each subject heading appears 

the universe or the type of entry being tabulated (shown in italics) and the relevant table number. Each 

variable is arranged alphabetically by universe, then by variable of cross tabulation, if any. If you are 

looking for a table tabulating age by sex for all persons, check the index under either of the two variables 

(“age” or “sex”). 

An asterisk (*) indicates that the matrix is also repeated by nine race and/or Hispanic or Latino groups. 

These matrices are identified in the file with a suffix that pertains to a specific group. For example, PCT13, 

when repeated for the White alone population, is labeled PCT13A. The nine groups, with their specific 

suffixes, are: 

White alone A suffix

Black or African American alone B suffix

American Indian and Alaska Native alone C suffix

Asian alone D suffix

Native Hawaiian and Other Pacific Islander alone E suffix

Some Other Race alone F suffix

Two or More Races G suffix

Hispanic or Latino H suffix

White alone, not Hispanic or Latino I suffix

 

One matrix, PCT12, is repeated not only for the above nine groups but also for the following:

Black or African American alone, not Hispanic or Latino J suffix

American Indian and Alaska Native alone, not Hispanic or Latino K suffix

Asian alone, not Hispanic or Latino L suffix

Native Hawaiian and Other Pacific Islander alone, not Hispanic or Latino M suffix

Some Other Race alone, not Hispanic or Latino N suffix

Two or More Races, not Hispanic or Latino O suffix

See the chapter, “List of Tables (Matrices)” for specific examples. 

Tables PCT23 and PCT24 are available only in the SF 1 Urban/Rural Update files.

Summary Level Sequence Chart

Summary levels specify the content and hierarchical relationships of the geographic elements that are 

required to tabulate and summarize data. In the Summary Level Sequence Chart that follows, the summary 

level code precedes the summary level area, and symbols are used with special meaning for summary 

levels: 

Hyphen “-” separates the elements of a hierarchy. 

Slash “/” denotes equivalent elements that have different names. 

Parentheses “( )” are not used in the specification for summary levels, but are used occasionally in the 

usual and customary manner in statements of clarification.

4. Indicates an iteration (repetition), for the specified summary level, of the data matrices on the 

summary file for a population or housing characteristic. These iteration fields apply to Summary File 2 

(SF 2) and the American Indian and Alaska Native Summary File only.

5. The sequence number of the table file within the set of physical files for the state (i.e., the geographic 

header record file and one or more table files). See “How to Use This Product” for more information.

6. The logical record is the complete record for a geographic entity defined by the summary level, but 

exclusive of the characteristic iteration. A logical record may have one or more parts (or segments). 

Each logical record has an assigned sequential integer number within the file. See “How to Use This 

Product” for further information.

7. See Appendix A, “Geographic Terms and Concepts,” for definition of this field.

8. The Federal Information Processing Standards (FIPS) codes were withdrawn as a standard in 2005. The 

Census Bureau, however, has renamed these codes as Federal Information Processing Series codes and 

retained the acronym. The two-digit state and congressional district and three-digit county FIPS codes 

(former FIPS 5, 9, and 6, respectively) are unchanged, but with oversight transferred to the American 

National Standards Institute (ANSI). The five-digit FIPS 55 codes are no longer a federal code standard; 

however they are retained in Census Bureau files as administrative codes and used as primary key 

codes for many geographic entity types. The U.S. Geological Survey has received ANSI oversight for a 

code standard that uses the Geographic Names Information System identifier (GNIS ID).

The new ANSI standard using the GNIS ID as the official codes for Named Physical and Cultural 

Geographic Features of the United States and Puerto Rico also is included in Census Bureau files for 

state, county, county subdivision, place, consolidated city, American Indian area, Alaska Native area, 

Hawaiian home land, American Indian tribal subdivision, and subminor civil division or equivalent 

features. The Census Bureau references these fields in the geoheader as ANSI codes and using the term 

National Standard code. The codes represent the official numeric GNIS ID as an eight-digit character 

field with leading zeroes. The Census Bureau treats the state and county or equivalent area ANSI codes 

as supplemental standard codes. 

The following lists the published code standards used for the 2010 Census (with its associated 

Census 2000 standard):

	 •	 INCITS.38-200x (R2004), Codes for the Identification of the States, the District of Columbia, Puerto

 Rico, and the Insular Areas of the United States (Formerly FIPS 5-2)

	 •	 INCITS.31-200x (R2007), Codes for the Identification of Counties and Equivalent Areas of the

 United States, Puerto Rico, and the Insular Areas of the United States (Formerly FIPS 6-4)

ENDNOTES—Con.

	 •	 INCITS.454-200x, Codes for the Identification of Metropolitan and Micropolitan Statistical Areas

 and Related Areas of the United States and Puerto Rico (Formerly FIPS 8-6)

	 •	 INCITS 455-200x, Codes for the Identification of Congressional Districts and Equivalent Areas of

 the United States, Puerto Rico, and the Insular Areas (Formerly FIPS 9-1)

	 •	 INCITS 446-2008, (GNIS) Identifying Attributes for Named Physical and Cultural Geographic

 Features (Except Roads and Highways) of the United States, Its Territories, Outlying Areas, and 

 Freely Associated Areas, and the Waters of the Same to the Limit of the Twelve-Mile Statutory Zone 

 (Formerly FIPS 55-4)

Note: INCITS refers to InterNational Committee for Information Technology Standards.

 23 5,000,000 or more

 The size code fields are not filled for the Redistricting Data Summary File products. 

10. Codes in unspecified arrangement for U.S. Census Bureau use.

11. Federal Information Processing Series (FIPS) 55 codes are assigned by state. Because American Indian 

areas and tribal subdivisions can exist in more than one state, multiple FIPS 55 codes can exist for the 

entity.

12. Urban Areas, Urban/Rural classification, ZIP Code Tabulation Areas, and Public Use Microdata Areas are 

not available in the Redistricting Data products.

13. Blank values in the Congressional District (111th) field indicate areas where no congressional district 

was assigned by state redistricting officials.

14. State legislative district codes have three characters and can include a hyphen (-). The code ZZZ 

indicates state legislative districts not defined. In the District of Columbia and Nebraska, both of which 

have a single legislative body, the state legislative districts are reported as upper chamber districts, 

and the lower chamber districts are coded as 999.

ENDNOTES—Con. 

15. Voting district codes can have one to six characters including special characters of a hyphen (-), dot 

(.), and forward slash (/). If the code contains less than six characters, the field is right-justified with 

leading blanks. The code ZZZZZZ indicates voting district not defined in a county or equivalent area 

containing one or more defined voting districts. A code of six blanks is used in Kentucky, Rhode Island, 

Oregon (except Multnomah County), and 14 of the 50 counties in Montana, where participants did not 

define voting districts for entire states or counties.

16. Land area measurement in square meters. The accuracy of the area measurement is limited by the 

inaccuracy inherent in the mapping of the various boundary features in the Census Bureau’s geographic 

database. Land area includes areas classified as intermittent water, swamps, and glaciers, which 

appear on census maps and in the Census Bureau’s geographic database as hydrographic features. 

Square miles can be derived by dividing square meters by 2,589,988. See Appendix A, “Geographic 

Terms and Concepts,” for definition of this field.

17. Water area measurement in square meters. The accuracy of the area measurement is limited by the 

inaccuracy inherent in the mapping of the various boundary features in the Census Bureau’s geographic 

database. Water area excludes areas classified as intermittent water, swamps, and glaciers, which 

are treated as land even though they appear on census maps and in the Census Bureau’s geographic 

database as hydrographic features. Square miles can be derived by dividing square meters by 

2,589,988. See Appendix A, “Geographic Terms and Concepts,” for definition of this field.

18. Name of the lowest-level entity represented by the summary level. In addition to the name of the 

entity, the name field contains the legal/statistical area description (LSAD), when appropriate, and 

sometimes contains the state abbreviation. For legal entities, the name is the one reported to the 

U.S. Census Bureau in the Boundary and Annexation Survey or by other appropriate sources, such 

as state education officials for school districts. For statistical entities, the name is determined by the 

Office of Management and Budget for metropolitan and micropolitan areas. The remaining statistical 

area names usually are supplied by tribal, state, or local sources according to published criteria. 

For redistricting data entities, names are reported by the state redistricting data liaison. For other 

areas, the name is determined by the local officials, usually in cooperation with the Bureau. When the 

summary level data represent only part of the area specified in the name, the name usually will have 

“(part)” appended to the name/code terminology to designate that this entry for the entity represents 

only a part of the total entity.

19. The total number of persons enumerated in the specified geographic entity as determined in the 

100 percent processing.

20. The total number of housing units enumerated in the specified geographic entity as determined in the 

100 percent processing.

21. Latitude in degrees, to seven decimal places, of a point within the geographic area represented by 

the summary level. The character immediately preceding the first digit of the latitude of an internal 

point identifies the direction (hemisphere): a plus sign (+) indicates the Northern Hemisphere; a minus 

sign (–) indicates the Southern Hemisphere. See Appendix A, “Geographic Terms and Concepts,” for 

definition of this field.

22. Longitude in degrees, to seven decimal places, of a point within the geographic area represented by 

the summary level. The character immediately preceding the first digit of the longitude of an internal

point identifies the direction (hemisphere): a plus sign (+) indicates the Eastern hemisphere; a minus 

sign (–) indicates the Western Hemisphere. A point on the 180th meridian is assigned to the Western 

Hemisphere (–180.0000000). See Appendix A, “Geographic Terms and Concepts,” for definition of this 

field.

other races P0060007 03 9

Note: The alone or in combination categories are tallies of responses rather than respondents. 

That is, the alone or in combination categories are not mutually exclusive. Individuals who 

reported two races were counted in two separate and distinct alone or in combination race 

categories, while those who reported three races were counted in three categories, and so on. 

For example, a respondent who indicated “White and Black or African American” was counted in 

the White alone or in combination category as well as in the Black or African American alone or 

in combination category. Consequently, the sum of all alone or in combination categories equals 

the number of races reported (i.e., responses), which exceeds the total population.

Note: A household that has at least one member of the household related to the householder 

by birth, marriage, or adoption is a “Family household.” Same-sex couple households are 

included in the family households category if there is at least one additional person related 

to the householder by birth or adoption. Same-sex couple households with no relatives of the 

householder present are tabulated in nonfamily households. Responses of “same-sex spouse” 

were edited during processing to “unmarried partner.” “Nonfamily households” consist of people 

living alone and households which do not have any members related to the householder.

Note 1: The numbers by American Indian and Alaska Native tribal grouping do not 

add to the total population. This is because the American Indian and Alaska Native tribal 

groupings are tallies of the number of American Indian and Alaska Native responses rather 

than the number of American Indian and Alaska Native respondents. Responses that include 

multiple American Indian and Alaska Native tribes are counted several times. For example, 

a respondent reporting “Apache and Blackfeet” would be included in the Apache as well as 

Blackfeet numbers. “Not specified” includes respondents who checked the American Indian or 

Alaska Native response category on the census questionnaire and did not write in a specific 

group or wrote in a generic term such as “American Indian” or “Alaska Indian.”

Note: “Families” consist of a householder and one or more other people related to the 

householder by birth, marriage, or adoption. They do not include same-sex married couples 

even if the marriage was performed in a state issuing marriage certificates for same-sex 

couples. Same-sex couples are included in the families category if there is at least one 

additional person related to the householder by birth or adoption. Responses of “same-sex 

spouse” were edited during processing to “unmarried partner.” Same-sex couple households 

with no relatives of the householder present are tabulated in nonfamily households.

H8. TOTAL RACES TALLIED FOR HOUSEHOLDERS [7]

Universe: Total races tallied for householders in 

occupied housing units

Total races tallied for householders: H0080001 44 9

White alone or in combination with one or more 

other races H0080002 44 9

Black or African American alone or in combination 

with one or more other races H0080003 44 9

American Indian and Alaska Native alone or in 

combination with one or more other races H0080004 44 9

Asian alone or in combination with one or more 

other races H0080005 44 9

Native Hawaiian and Other Pacific Islander alone or 

in combination with one or more other races H0080006 44 9

Some Other Race alone or in combination with one 

or more other races H0080007 44 9

Note: The alone or in combination categories are tallies of responses rather than 

respondents. That is, the alone or in combination categories are not mutually exclusive. 

Individuals who reported two races were counted in two separate and distinct alone or in 

combination race categories, while those who reported three races were counted in three 

categories, and so on. For example, a respondent who indicated “White and Black or African 

American” was counted in the White alone or in combination category as well as in the Black 

or African American alone or in combination category. Consequently, the sum of all alone or in 

combination categories equals the number of races reported (i.e., responses), which exceeds 

the total number of householders.

Note: A household that has at least one member of the household related to the householder 

by birth, marriage, or adoption is a “Family household.” Same-sex couple households are 

included in the family households category if there is at least one additional person related 

to the householder by birth or adoption. Same-sex couple households with no relatives of the 

householder present are tabulated in nonfamily households. Responses of “same-sex spouse” 

were edited during processing to “unmarried partner.” “Nonfamily households” consist of people 

living alone and households which do not have any members related to the householder.

Note: A household that has at least one member of the household related to the householder 

by birth, marriage, or adoption is a "Family household." All persons living in family households 

are included in this total regardless of their relationship to the householder. Same-sex couple 

households are included in the family households category if there is at least one additional 

person related to the householder by birth or adoption. Same-sex couple households with 

no relatives of the householder present are tabulated in nonfamily households. "Nonfamily 

households" consist of people living alone and households which do not have any members 

related to the householder. "Spouse" represents spouse of the householder. It does not reflect 

all spouses in a household. Responses of "same-sex spouse" were edited during processing 

to "unmarried partner." Nonrelatives include any household member not related to the 

householder by birth, marriage, or adoption. This includes unmarried partners.

MASTER ADDRESS FILE DEVELOPMENT

As in Census 2000, the base for the address list for the 2010 Census was the address list from the 

previous census. Various updates were made to the address list during the intervening decade. The 

primary source of new addresses after Census 2000 was the Delivery Sequence File (DSF) from the

U.S. Postal Service (USPS). The U.S. Census Bureau acquired this file of all mailing addresses in the United 

States and updated the Master Address File (MAF) twice a year (March and October) until February 2010. 

Addresses must be associated with a block to be included in the census. The process of associating these 

addresses with a block is called geocoding. For the Census Bureau, the file where geographic information 

is contained is the Topologically Integrated Geographic Encoding and Referencing System (TIGER®). During 

this decade, the MAF and TIGER® have been integrated into the MAF/TIGER® database (MTdb). 

For the processing of the DSF records, city-style addresses (containing a house number and street name) 

of residential units were applied to the MAF in those blocks that, in general terms, had been found to 

have a majority of city-style addresses in order that duplication would not result from the addition of 

these addresses. Another file from the USPS, the Locatable Address Conversion System (LACS), contained 

linkages for addresses that had been changed. Use of this file by the Census Bureau allowed for old 

and new addresses to be linked in the MTdb. This was especially desirable for linking the non-city-style 

addresses that had been converted to city-style addresses. 
7-2 2010 Census: Operational Overview and Accuracy of the Data

U.S. Census Bureau, 2010 Census Summary File 1

Various field operations, such as census tests and the update of rural area addresses for the American 

Community Survey, led to localized updates or updates in specific types of areas. In particular, updating 

addresses with post office box type addresses in the rural area was meant to balance the updating of the 

MTdb with city-style addresses from the DSF. 

Local Update of Census Addresses

The first large-scale update of addresses for the decennial census was the Local Update of Census 

Addresses (LUCA) program. In this program, governmental units (GUs) were allowed to participate in 

updating the address list in three different ways. One option allowed for review of the Census Bureau’s 

address list, while the other options allowed only for the GUs to submit a list of addresses to the Census 

Bureau. Under any of these options, new addresses submitted by the GUs were included on the subsequent 

address list. These addresses could be for housing units (HUs) or for group quarters (GQs). The submitted 

addresses were then included in the universe for validation in the next major address list development 

operation, Address Canvassing, which occurred between April and July 2009. 

Address Canvassing

Address Canvassing was conducted in all areas of the United States and Puerto Rico except in the areas 

that were designated for Remote Alaska or Remote Update Enumerate in the census. Address Canvassing 

was a dependent check of the list of addresses, as well as of the maps. The Address Canvassing operation 

was performed using automation, which allowed for the integration of address and map updates, as 

well as the imposition of rules on what constitutes a minimum allowable address and the collection of 

particular geographic fields. The allowable actions on the addresses in Address Canvassing were validate, 

nonresidential, delete, duplicate, address correction, and an action for designating possible GQs. Adds 

to the list were also allowed. All deletes and duplicates were validated during the next phase of the 

operation, called delete verification. The results from Address Canvassing were incorporated into the 

MTdb. One of the first uses of these results was for creating feedback to the GUs participating in LUCA. 

The results from processing the Address Canvassing updates were also used for the creation of the initial 

census address list starting in July 2009, the initial Universe Control and Management (UC&M) file. Printing 

of the questionnaires used this address list. 

Group Quarters

The results of Address Canvassing also contributed to the universe for the next operation, which was 

Group Quarters Validation (GQV). The procedures for creating the address list of GQs were significantly 

different for the 2010 Census as opposed to previous censuses. In order to reduce duplication and 

geographic data errors, the address lists of HUs and GQs were integrated in the MTdb. The list of potential 

GQs going into GQV was the accumulation of GQ addresses from Census 2000, GQ addresses acquired 

from various sources, and addresses listed as Other Living Quarters (potential GQs) in Address Canvassing. 

Cases designated as GQs through other sources were intended to be sent to GQV regardless of the Address 

Canvassing status. However, it was discovered during processing of the LUCA updates that GUs often 

listed apartment buildings or commercial units as GQs. The schedule for completing GQV, in October 2009, 

was one of the riskiest in the census. For these units to remain on the list of units to be checked in GQV 

put timely completion of the operation at risk, and thus, the entire census schedule. Therefore, from the 

LUCA updates making their way to GQV, only the units with facility names that included special key names 

known to be associated with group quarters were designated for follow-up in GQV unless they were also 

designated as possible GQs in Address Canvassing. The addresses in GQV could receive an action of GQ—

along with the type of GQ, HU, nonresidential, vacant, transient (meaning the location was connected to a 

geographic area that should be enumerated in the Enumeration at Transitory Locations operation), delete, 

or duplicate.

The results from GQV were processed in November 2009. Updates were made to the initial UC&M, 

resulting in the enumeration UC&M, or the full census universe. Units that were marked as housing units 
2010 Census: Operational Overview and Accuracy of the Data 7-3

U.S. Census Bureau, 2010 Census Summary File 1

in GQV were designated as adds to the initial UC&M universe. Other adds to this universe resulted from 

DSF updates that had occurred between the creation of the Address List for Address Canvassing and the 

creation of the enumeration UC&M. There were three DSFs contributing new adds to this UC&M file. A 

supplemental printing of addressed questionnaires resulted from this updated file. These questionnaires 

were either added to the mail stream at the point that questionnaires were delivered by the USPS or sent to 

the Local Census Offices in those areas where the added addresses occurred in Update/Leave areas. 

Update/Leave

Update/Leave (U/L) is an operation in which questionnaires are hand-delivered due to potential 

problems with postal delivery of addresses. The presence of staff in the field for this delivery allows the 

simultaneous updating of the address lists and maps. Addresses on the address list in U/L areas received 

the actions of verify, correction, nonresidential, delete, or duplicate. Maps could also receive updates. The 

operation occurred between March 1 and April 2, 2010. There were approximately 12 million housing 

units in stateside U/L areas, and Puerto Rico (about 1.6 million addresses) was entirely U/L. There was no 

check on the deletes and duplicates designated in this operation because the operation was performed on 

paper and there was a timing issue with processing. The status of nonresponding units that were in the 

enumeration universe was checked in the later Nonresponse Follow-Up operation. 

Nonresponse Follow-Up

Nonresponse Follow-Up (NRFU) is the operation in which nonresponding households from both mailout/

mailback and U/L areas are followed up and enumerated, if possible. Other options within NRFU are to 

mark the unit vacant (either a regular vacant or seasonal), delete, or duplicate. It is also possible to add 

units and perform the enumeration on them. The maps also may be updated. The status of regular vacants 

and deletes is checked in the subsequent operation, the Vacant/Delete Check. 

Other Address and Geocoding Operations

No additional updates were made to the enumeration universe in the UC&M before the start of NRFU. 

However, there were still operations and processes adding addresses to the MTdb, or in some cases, 

adding geographic data that allowed the addresses to be included in the census. These were: 1) LUCA 

Appeals; 2) New Construction; 3) HU Address Review; 4) Count Review; 5) Spring 2010 DSF; 6) newly 

geocoded addresses; 7) addresses resulting from a follow-up of INFO-COMMs (standardized forms used to 

document problems, issues, and unusual situations or to ask questions about procedures and other workrelated matters by field staff) submitted during Address Canvassing; and 8) U/L added addresses. 

LUCA Appeals was a process where a GU that participated in LUCA submitted challenges to the outputs 

from Address Canvassing. The challenged addresses were reviewed, and those that were approved were 

accepted back onto the census list.

New Construction was an effort similar to LUCA in which the participating GU submitted addresses that 

represented newly constructed and livable housing.

The HU Address Review was a headquarters review of addresses coming from a variety of sources. In 

general, these were people who reported situations, such as large apartment buildings missing from the 

census universe, where the report made it to headquarters personnel. Staff in the Geography Division 

researched these address submissions to determine if they were truly missing from the census address list 

and, if so, why. When it was found that addresses should be included on the census address list and did 

not duplicate other addresses already on the census address list, they were submitted for processing in 

the same format as files from the New Construction and Count Review programs.

Count Review was another effort undertaken with governmental representatives with an eye toward 

identifying housing that was missing from the list.
7-4 2010 Census: Operational Overview and Accuracy of the Data

U.S. Census Bureau, 2010 Census Summary File 1

The Spring 2010 DSF contained mailable addresses as of February 2010. Residential addresses appearing 

on this list that were not already included in the MTdb were assumed to represent mostly newly 

constructed units. For the next source of addresses on this update, there were a few million addresses 

residing on the MTdb that had not yet been geocoded. It was assumed that these addresses would be 

added in Address Canvassing if they truly existed.

However, when Address Canvassing was completed and only about half of the addresses had been added 

in the operation, and at the same time there were some concerns about the coverage of the list, the 

Census Bureau undertook an independent effort in early 2010 to find geocodes for these units after first 

checking that the addresses were not represented on the list in another form.

The next addition of addresses resulted from Address Canvassing INFO-COMMs. The design of the 

automated instrument did not allow for units to be added during the Quality Control (QC) phase of the 

operation if the assignment had passed QC. Nevertheless, in some areas QC staff found large numbers 

of missing addresses that were not picked up within the QC sample. They filled out an INFO-COMM to 

apprise the local office staff of the situation. In early 2010, there was an effort to identify which of these 

cases were really missing units and where they should be added to the list. An input file that mimicked the 

inputs of the other operations adding addresses was created for these units to be added to the census list 

in this process, as well.

The final source of new addresses listed here was U/L adds. These are units that did not appear on the list 

used for U/L but that were identified as valid in the field. Questionnaires were delivered to these units, and 

updates were made to the MTdb based on the results of this operation. However, the processing of U/L 

actions could not be completed in time to update the NRFU universe without automation. Thus, in order 

to perform enumeration on U/L adds for households that did not return the form, the units needed to be 

included in the subsequent updated universe. 

Vacant/Delete Check

These addresses just described made it into the enumeration universe for the first time for the Vacant/

Delete Check (VDC). Not all of these addresses required a visit for enumeration during the VDC. In 

particular, if a householder at an address added during U/L mailed in the form in time, no additional visit 

was required. In addition, an operation dubbed the Late Add Mailing resulted in many of these addresses 

being mailed forms earlier than enumeration would have occurred. In particular, the LUCA Appeals 

addresses, the addresses from the most recent DSF that were geocoded to a block, and the addresses that 

were newly geocoded during the geocoding research were placed on a file for which questionnaires were 

printed and mailed. A unique processing ID was printed on each of these questionnaires, which enabled 

the questionnaires to be linked up to the census ID that was used when the units were added to the VDC 

universe. This also allowed for the information about receipt of a questionnaire to be passed back to the 

universe file and removed from the universe of follow-up cases. Therefore, the final list of units requiring 

follow-up and potential enumeration in VDC were the regular vacants and deletes as designated in NRFU 

and the new units added from the seven sources listed above for which no questionnaire was received 

by the time of universe creation. The universe of addresses printed within the address registers were all 

units that appeared in the enumeration universe plus the units added from the seven sources listed. One 

category of new address that did not appear on the VDC listing pages, due to timing, were the units that 

were added during NRFU. 

Field Verification

There was one final check of particular addresses in the field. This operation is called Field Verification, 

and it was performed in the 2010 Census much as it was in Census 2000. Only specific addresses within 

the entire universe of addresses were acted on during this status check. Units designated for follow-up in 

this operation received a status of valid (or verify), delete, or duplicate. The addresses in the universe for 

this check in the 2010 Census included two categories of cases. The first was a check of new addresses 

that resulted from Be Counted forms or calls to the Telephone Questionnaire Assistance line that did not 
2010 Census: Operational Overview and Accuracy of the Data 7-5

U.S. Census Bureau, 2010 Census Summary File 1

have a related census ID. These addresses needed to be verified in the field before they were added to 

the census. They must be associated with a particular block before they could be sent for field work. The 

second category of cases was units that potentially needed to be removed from the universe based on 

the identification of duplicated persons in those units. Person duplication occurs for many reasons, one of 

which is duplication of housing units on the address list. Units linked by person matching that are within 

a close geographic area have been found in testing to be highly associated with housing-level problems. 

However, there are other situations that can lead to such person duplication that are not housing unit 

duplication, so these units identified as potential duplicates needed to be field checked before they could 

be safely removed from the census address list. For those units that were designated as duplicates, an 

indicator of which unit on the list that unit duplicated was collected.

Remote Areas

The descriptions above cover the vast majority of housing units in the United States and in all of Puerto 

Rico. However, there are some particularly remote or problematic areas that were designated for other 

types of enumeration. The first of these to start was Remote Alaska. In this operation, enumeration was 

scheduled to occur in fishing and hunting villages before the ice broke and the villagers scattered from 

their winter homes. Other areas in Alaska that were remote but where the population is stationary were 

designated for Remote Update/Enumerate. The methodology is the same for these two operations. The 

incoming address list was based on what was there during Census 2000. Updates were made to the 

address list and maps, and the households were enumerated at the same time. An area of Maine was also 

designated for Remote Update/Enumerate. 

Some areas of the country (covering about 1.5 million addresses) were designated for Update/Enumerate. 

In these areas, Address Canvassing was completed, but it was felt that enumeration by Mailout/Mailback 

or U/L would have been problematic. These areas could be seasonal housing, federally designated tribal 

areas, or areas with particularly low predicted response rates based on various demographic factors. 

In Update/Enumerate, as in Remote Update/Enumerate and Remote Alaska, updates were made to the 

address list and maps at the same time that enumeration was completed. In general, this is the last 

operation that occurs in these areas, although it is possible for units in the Field Verification universe to be 

in these areas. 

GROUP QUARTERS ENUMERATION

A list of nonstandard housing, such as college dormitories and group homes, was tracked in the MTdb in 

conjunction with the housing unit list. The list of these GQs was compiled from various sources, including 

the Census 2000 list of GQs, LUCA participants, the Federal-State Cooperative for Population Estimates, 

and Address Canvassing. The GQV of these addresses occurred in October 2009, as described above. 

The units that remained GQs after this check were included in Group Quarters Advance Visit (GQAV), and 

then Group Quarters Enumeration (GQE). In GQE, individual census questionnaires—meaning individual 

questionnaires for each person—were distributed at the GQs and collected by the field staff. A count of 

persons associated with a particular GQ resulted from this operation. 

SERVICE-BASED ENUMERATION AND ENUMERATION AT TRANSITORY LOCATIONS

Service-Based Enumeration (SBE) was designed to account for the enumeration of persons without a usual 

residence that use service facilities (i.e., shelters, soup kitchens, and mobile food vans). In the

2010 Census, 3 days (March 29–31) were designated for these enumeration activities. Different types of 

facilities were designated for different days. Only persons using the service facility on the interview day 

were enumerated at that location. It was possible for people to be counted in more than one location due 

to use of different facilities on subsequent days. There is an unduplication of SBE persons for the purpose 

of minimizing this duplication. 
7-6 2010 Census: Operational Overview and Accuracy of the Data

U.S. Census Bureau, 2010 Census Summary File 1

People experiencing homelessness could also complete a Be Counted form and check the box indicating 

this status. To the extent that such persons could be associated with a state and county based on the 

information provided on the form, they will be counted at a Group Quarters within that state and county. 

Certain areas were designated for Enumeration at Transitory Locations (ETL). These included RV parks 

and marinas where people were living as of Census Day if people living in these locations had no other 

permanent place to stay. The locations where ETL took place were designated in GQAV. When people were 

enumerated in ETL, the particular location was considered a housing unit. 

CONFIDENTIALITY OF THE DATA

The Census Bureau has modified some data in this data release to protect confidentiality. Title 13 U.S. 

Code, Section 9, prohibits the Census Bureau from publishing results in which an individual’s data can be 

identified.

The Census Bureau’s internal Disclosure Review Board monitors the disclosure review process and sets the 

confidentiality rules for all data releases. A checklist approach is used to ensure that all potential risks are 

considered and addressed. A list of possible concerns is created and the Disclosure Review Board makes 

sure that the appropriate steps are taken to assure the confidentiality of the data. 

Title 13 U.S. Code

Title 13 of the U.S. Code authorizes the Census Bureau to conduct surveys and censuses and mandates 

that any information obtained from private individuals and establishments remains confidential. Section 

9 of Title 13 prohibits the Census Bureau from releasing “any publication whereby the data furnished 

by any particular establishment or individual under this title can be identified.” Section 214 of Title 13, 

as modified by the Federal Sentencing Reform Act, imposes a fine of not more than $250,000 and/or 

imprisonment of not more than 5 years for publication or communication in violation of Section 9.

Disclosure Avoidance

Disclosure avoidance is the process of disguising data to protect confidentiality. A disclosure of data 

occurs when someone can use published statistical information to identify an individual who provided 

information under a pledge of confidentiality. Using disclosure avoidance, the Census Bureau modifies or 

removes all of the characteristics that put confidential information at risk for disclosure. Although it may 

appear that a table shows information about a specific individual, the Census Bureau has taken steps (such 

as data swapping) to disguise the original data while making sure the results are useful.

Data Swapping

Data swapping is a method of disclosure avoidance designed to protect confidentiality in tables of frequency 

data (the number or percentage of the population with certain characteristics). Data swapping is done by 

editing the source data or exchanging records for a sample of cases. A sample of households is selected and 

matched on a set of selected key variables with households in neighboring geographic areas (geographic 

areas with a small population) that have similar characteristics (same number of adults, same number of 

children, etc.). Because the swap often occurs within a geographic area with a small population, there is no 

effect on the marginal totals for the geographic area with a small population or for totals that include data 

from multiple geographic areas with small populations. Because of data swapping, users should not assume 

that tables with cells having a value of one or two reveal information about specific individuals.

NONSAMPLING ERROR

In any large-scale statistical operation, such as the 2010 Census, human- and computer-related errors 

occur. These errors are commonly referred to as nonsampling errors. Such errors include not enumerating 

every household or every person in the population, not obtaining all required information from the 

respondents, obtaining incorrect or inconsistent information, and recording information incorrectly. In 
2010 Census: Operational Overview and Accuracy of the Data 7-7

U.S. Census Bureau, 2010 Census Summary File 1

addition, errors can occur during the field review of the enumerators’ work, during clerical handling of the 

census questionnaires, or during the electronic processing of the questionnaires.

While it is impossible to completely eliminate nonsampling error from an operation as large and complex 

as the decennial census, the Census Bureau attempts to control the sources of such error during the 

collection and processing operations. Described below are the primary sources of nonsampling error and 

the programs instituted to control this error in the 2010 Census. The success of these programs, however, 

was contingent upon how well the instructions actually were carried out during the census. 

Types of Nonsampling Error

Nonresponse

Nonresponse to particular questions on the census questionnaire or the failure to obtain any information 

for a housing unit allows for the introduction of bias into the data because the characteristics of the 

nonrespondents have not been observed and may differ from those reported by respondents. As a result, 

any imputation procedure using respondent data may not completely reflect these differences either at 

the elemental level (individual person or housing unit) or on the average. Some protection against the 

introduction of large biases is afforded by minimizing nonresponse. Characteristics for the nonresponses 

were imputed by using reported data for a person or housing unit with similar characteristics.

Respondent and Enumerator Error

The person answering the mail questionnaire for a household or responding to the questions posed by 

an enumerator could serve as a source of error, although the question wording was extensively tested in 

several experimental studies prior to the census. The mail respondent may overlook or misunderstand a 

question or answer a question in a way that cannot be interpreted correctly by the data capture system. 

The enumerator may also misinterpret or otherwise incorrectly record information given by a respondent 

or may fail to collect some of the information for a person or household. To control problems such as 

these with the field enumeration, the work of enumerators was monitored carefully. Field staff were 

prepared for their tasks by using standardized training packages that included hands-on experience in 

using census materials. A sample of the households interviewed by each enumerator were reinterviewed 

to control for the possibility of fabricated data being submitted by enumerators.

Processing Error

The many phases involved in processing the census data represent potential sources for the introduction 

of nonsampling error. The processing of the census questionnaires completed by enumerators included 

field review by the crew leader, check-in, and transmittal of completed questionnaires. No field reviews 

were done on the mail return questionnaires for this census.

Error may also be introduced by the misinterpretation of data by the data capture system or the failure to 

capture all the information that the respondents or enumerators provided on the forms. Write-in entries 

go through coding operations, which may also be a source of processing error in the data. Many of the 

various field, coding, and computer operations undergo a number of quality control checks to help ensure 

their accurate application.

Reduction of Nonsampling Error

To reduce various types of nonsampling errors, a number of techniques were implemented during the 

planning, development of the mailing address list, data collection, and data processing activities. Quality 

assurance methods were used throughout the data collection and processing phases of the census to 

improve the quality of the data. A reinterview program was implemented to minimize the errors in the data 

collection phase for enumerator-filled questionnaires.
7-8 2010 Census: Operational Overview and Accuracy of the Data

U.S. Census Bureau, 2010 Census Summary File 1

Several coverage improvement programs were implemented during the development of the census address 

list and census enumeration and processing to minimize undercoverage of the population and housing 

units. These programs were developed based on experience from previous decennial censuses and results 

from the 2010 Census testing cycle. 

•	 Be Counted questionnaires, unaddressed forms requesting all questionnaire items plus a few additional

items, were available in public locations for people who believed they were not otherwise counted.

• 	An introductory letter was sent to all mailout/mailback addresses and many addresses in update/leave

areas prior to the mailing of the census form. A reminder postcard was also sent to these addresses.

• 	A replacement questionnaire was sent to nonresponding addresses in selected areas.

• 	Bilingual English/Spanish questionnaires were sent to all addresses in selected areas.

•	 Forms in Spanish, Chinese (simplified), Korean, Russian, and Vietnamese were mailed to those who

requested them and Language Assistance Guides were available in 59 languages.

•	 A well-publicized toll-free phone number was available to answer questions about the forms, and

responses could be taken over the phone.

•	 Under the LUCA program, local officials had the opportunity to address specific concerns about the

accuracy and completeness of the address list.

•	 A Coverage Followup (CFU) telephone interview operation was implemented with the express purpose

of improving within household coverage. Cases were telephoned when there was a discrepancy 

between the number in the count of persons box and the number of persons with data. A householdlevel undercoverage question was added to the questionnaire, and person-level overcoverage questions 

were also added. Certain categories of households checking these boxes were also selected for CFU 

for roster clarification. In addition, large households, or those with more than six household members, 

were selected for inclusion in CFU for the purpose of collecting full demographic data for persons 

beyond the first six. 

Resolving Multiple Responses

With multiple ways for people to initiate or complete their enumeration, as well as the field follow-up 

operations, it was very likely that some households would be enumerated more than once. A special 

computer process was implemented to control the extent of this type of nonsampling error by resolving 

situations where more than one form was received from an address. The process consisted of several 

steps. Addresses that had more than one viable return were analyzed. Household data from one form 

were chosen as the household data to use in subsequent census processing. There are situations in which 

persons can then be added to the household roster if they are not already represented there. These are the 

cases in which a Be Counted form for a partial household was submitted for the same address, and when 

an enumeration operation discovers a person who should be counted at a different address (a Usual Home 

Elsewhere) from the address being enumerated. 

DATA EDITING 

The objective of the processing operation was to produce a set of data that describes the population as 

accurately and clearly as possible. As with Census 2000, information on 2010 Census questionnaires 

generally was not edited for consistency, completeness, and acceptability during field data collection

nor during data capture operations. Enumerator-filled questionnaires were reviewed by census crew 

leaders and local office clerks for adherence to specified procedures. No clerical review of mail return 

questionnaires was done to ensure that the information on the form could be data captured, nor were 

households contacted to collect data that were missing from census returns as in previous censuses. 
2010 Census: Operational Overview and Accuracy of the Data 7-9

U.S. Census Bureau, 2010 Census Summary File 1

Most census questionnaires received by mail from respondents as well as those filled by enumerators were 

processed through a new contractor-built image scanning system that used optical mark and character 

recognition to convert the responses into computer files. The optical character recognition, or OCR, process 

used several pattern and context checks to estimate accuracy thresholds for each write-in field. The system 

also used edits on interpreted write-in responses to decide whether the field values read by the machine 

interpretation were acceptable. If the value read had a lower than acceptable accuracy threshold or was 

outside of the edit range, the image of the item was displayed to a keyer, who then entered the response.

To control the creation of possibly erroneous persons from questionnaires completed incorrectly or 

containing stray marks, an edit on the number of persons indicated on each mail return and enumeratorfilled questionnaire was implemented as part of the data capture system. In addition, a new edit identified 

questionnaires with information written outside of the response boxes. Detection of either of these 

conditions by the edits subsystem resulted in the review of the questionnaire image at a workstation by an 

operator who ensured that the person data were captured fully and correctly. 

At Census Bureau headquarters, the data records were subjected to a computer edit that identified 

households exhibiting a possible coverage problem and those with more than six household members. 

Attempts were made to contact these households on the telephone to correct the count inconsistency and 

to collect the census data for those people for whom there was no room on the questionnaire.

Count Imputation 

Once census processing is completed, each address included in the census data collection has to be 

classified as a nonexistent unit, a vacant unit, or an occupied housing unit. Records that are classified 

as an occupied unit also need a reported number of residents. This information is necessary to have a 

complete count of the population and housing units in the United States as of Census Day. Because of the 

complexity of census operations, there are records that do not have such information by the end of the 

follow-up activities and data processing. To fill in this missing information, the Census Bureau conducted 

count imputation, which assigns a unit status and household size to records without such information. 

This process also included assigning household size to occupied units without household size information. 

Count imputation processing did not include group quarters.

In count imputation, all the records in the enumeration universe were partitioned within a designated 

geographical area into small groups based on certain characteristics. For each small group, a probability 

distribution of unit status and size from the records that had this information was created. Then, the 

distribution was used to impute for the missing data status and/or household size.

General Imputation Rules

The final automated edit and imputation processes determined the final values of questionnaire data items 

for records with missing or invalid values in collected data. Imputations, which were needed most often 

when an entry for a given item was missing, included three general procedures known as assignments, 

allocations, and substitution. Assignments and allocations were imputations of characteristic items on an 

item-by-item basis, whereas the substitution process imputed data for up to six persons in a household 

at one time. Each of these procedures ensured the completeness and consistency of the data by providing 

acceptable codes for missing or unacceptable entries.

The first step in the edit process was to assign acceptable codes in place of unacceptable entries or blanks 

when acceptable data were found for that same person. When one characteristic item reported for a person 

was inconsistent with other information provided for that same person, acceptable codes or values that 

were consistent with one item of reported information were assigned. The edit procedures also assigned 

race or Hispanic origin from a matched person record in Census 2000 or in the American Community 

Survey (2000–2009) when these fields were missing. These assignment steps strove to ensure consistency 

across characteristic data.

U.S. Census Bureau, 2010 Census Summary File 1

The next step in the edit process, known as allocation, was to impute responses for missing person 

or housing-unit characteristic data. The general procedure for changing unacceptable entries through 

allocation was to derive an entry for a person (or housing unit) that was consistent with entries for another 

person (or housing unit) with similar characteristics. Allocation rates for census items were made available 

with the published census data.

Another way corrections are made during the edit and imputation process was through substitution; that 

is, the replication of a full set of characteristics for people in a household. When there was an indication 

that a household was occupied by a specified number of people but the questionnaire record contained no 

information for the people within the household or the occupants were not listed on the questionnaire, a 

previously accepted household of the same size was selected as a substitute. The full set of characteristics 

of the substitute was duplicated. Counts of substituted persons and the occupied housing units containing 

substituted persons were made available with the published census data.

Technical Note on Comparing Statistics on Same-Sex-Couple Households Between the 2010 

Census and the American Community Survey

Tabulations from the 2010 Census Summary File 1 present detailed geographical information on the 

number of same-sex unmarried-couple households. This number combines those who initially reported 

that they were spouses of the householder and those who were unmarried partners of the householder. 

Tables PCT15 and PCT17 in Summary File 1 show the presence of children in the household. 

In the Same-Sex-Couple Households Summary File, released after Summary File 1, an additional table 

further specifies if the partner of the householder reported that he or she was the spouse of the 

householder. This is the first time such detailed data have been released from any decennial census.

Since 2005, statistics on characteristics of same-sex-couple households—both for those identified as 

spouses and as unmarried partners—have been released from the American Community Survey (ACS).1 

The American Community Survey is a nationally representative household survey of 3 million households 

that contains detailed social, economic, and housing items formerly contained on the long or sample form 

of the decennial census. 

Data users are advised not to make comparisons of estimated numbers of same-sex-couple households 

between the ACS and the 2010 Census because of differences in data collection procedures. Although the 

majority of both ACS and census returns were collected via mail, differences occur in the data collection 

instruments for the households not responding by mail. 

For the 2010 Census, individual enumerators were sent out to the nonresponding households and were 

administered a paper form for Nonresponse Follow-Up (NRFU). The ACS did not employ a paper form for 

follow-up but collected the information in person using a laptop computer (CAPI) or by telephone using 

a computerized instrument (CATI). These instruments had a key collection component that was absent 

from the paper form. When an interviewer recorded that a household was headed by a same-sex spouse, a 

message in a “pop-up box” appeared on the instrument screen that prompted the interviewer to verify the 

responses to the relationship and the gender items. Previous Census Bureau research has demonstrated 

the sensitivity of same-sex-couple estimates to different data collection procedures.2 Subsequent analysis 

of 2010 Census data on same-sex-couple households will be forthcoming and will address any differences 

noted between the 2010 Census and the ACS in the estimates of same-sex-couple households.

In September 2012, the Census Bureau released the Summary File 1 (SF 1) Urban/Rural Update, making 

data available for additional geographic summary levels and geographic components related to urban and 

rural areas. In addition, the Urban/Rural Update adds two new tables to SF 1: 

PCT23 Race

PCT24 Household Type by Relationship for the Population 65 Years and Over 

Also, tables P2 (Urban and Rural, Universe: Total population) and H2 (Urban and Rural, Universe: Total 

housing units) are filled with data. 

In American FactFinder, data are available as detailed tables, quick tables, and geographic comparison 

tables. The Demographic Profile is available from the Summary File 1 Urban/Rural Update as a quick table 

in American FactFinder. 

The SF 1 Urban/Rural Update also is available in ASCII format via the FTP site. The FTP site provides 

separate files for the United States, 50 states, the District of Columbia, and Puerto Rico. 

The following changes were made to the technical documentation for Summary File 1:

Abstract. A second citation is added. The sections on “Subject Content,” “Geographic Content,” “User 

Updates,” and “Related Products” are revised.

How to Use This Product. The sections on “Data Format and Access Tools” and “Data Structure and 

Segmentation” are revised to reference the availability of the SF 1 Urban/Rural Update files, and provide 

information on file segments that exceed 255 fields.

Figure 2-2 on file segmentation is revised, and additional charts are added to Figure 2-5.

Subject Locator. Two new tables (PCT23 and PCT24) are added. These two tables are referenced in the 

subject locator under the categories of Race (PCT23), Household Type (PCT24), and Relationship (PCT24).

Summary Level Sequence Chart. Additional geographic summary levels and geographic components 

are displayed in a new set of summary level sequence charts.

List of Tables (Matrices). Two new tables (PCT23 and PCT24) are added, under the new heading 

“Population Subjects (Summarized to the Census Tract Level) for the SF 1 Urban/Rural Update.” 

See Page 5-14.

Data Dictionary. In the Identification Section (Record Codes), new file identification codes are listed. In 

the Table (Matrix) Section, the introductory text is revised (see Page 6 -21), and two new tables (PCT23 and 

PCT24) are added (see Pages 6-348 and 6-349).

Changes to Chapter 5, List of Tables (Matrices)

On pages 5-18 and 5-19, the cell count was added to tables PCT22C and PCT22E. On page 5-21, the title 

of table H22 was corrected to remove a misplaced cell count. On page 5-21, the cell count for table H11B 

was added.

Changes to Chapter 6, Data Dictionary

On page 6-272, table PCT13G, in the Table Contents column, the second occurrence of male age 

group label “85 years and over” was deleted from the line displaying Data Dictionary Reference Name 

PCT013G025, and the preceding 22 male age group labels, beginning with “5-9 years,” were moved down 

by one row. The age group “Under 5 years” was added to the line displaying Data Dictionary Reference 

Name PCT013G003. This change was also made on page 6-273, for table PCT13H. The labels of tables 

PCT13A, PCT13B, PCT13C, PCT13D, PCT13E, PCT13F, and PCT13I were correct and are unchanged.

INTRODUCTION

This document provides definitions of geographic terms and concepts as well as a description of the 

different methods used to present information for geographic entities in U.S. Census Bureau data products. 

This document contains definitions for all geographic area terms and concepts recognized by the Census 

Bureau and that may appear in any Census Bureau product presenting demographic and housing data 

(geographic terms and concepts unique to the economic census and other specialized surveys and 

censuses are not included in this document). The inclusion of a particular term or concept in this 
A-4 Geographic Terms and Concepts

 U.S. Census Bureau, 2010 Census Summary File 1

document does not imply that data for that geographic entity or attribute appear in each data 

product. For instance, data for tribal census tracts and tribal block groups will appear only in products 

providing data according to the American Indian Nation-based geographic hierarchy (see Figure A-2). As 

another example, because urban areas are defined on the basis of decennial census population counts, 

data for urban areas do not appear in initial decennial census data products. In addition, the description of 

both the hierarchical and inventory approaches to presenting data for geographic entities does not imply 

that both formats are used in each data product.

GEOGRAPHIC PRESENTATION OF DATA

In Census Bureau data products, geographic entities usually are presented in a hierarchical arrangement or 

as an inventory listing.

Hierarchical Presentation

A hierarchical geographic presentation shows the geographic entities in a superior/subordinate 

structure. This structure is derived from the legal, administrative, or areal relationships of the entities. 

The hierarchical structure is depicted in report tables by means of indentation. For computer-readable 

media, the hierarchy is shown in the descriptive name applied to a summary level, with the hierarchy 

in order separated by hyphens. An example of hierarchical presentation is the census geographic 

hierarchy consisting of census block, within block group, within census tract, within place, within county 

subdivision, within county, within state. Graphically, this is shown as:

State 

 County 

 County subdivision 

 Place (or part) 

 Census tract (or part) 

 Block group (or part) 

 Block

Figure A-1, which is a diagram of the geographic hierarchy, presents this information as a series of nesting 

relationships. For example, a line joining the lower-level entity place and the higher-level entity state 

means that a place cannot cross a state boundary; a line linking census tract and county means that a 

census tract cannot cross a county line; and so forth. There is no implied hierarchy between different line 

tracks; for example, census tract nests within county, but it may cross a county subdivision boundary even 

though county subdivision also nests within county.

Inventory Presentation

An inventory presentation of geographic entities is one in which all entities of the same type are shown in 

alphabetical, code, or geographic sequence, without reference to their hierarchical relationships. Generally, 

an inventory presentation shows totals for entities that may be split in a hierarchical presentation, such as 

place, census tract, or block group. An example of a series of inventory presentations is state, followed by 

all the counties in that state, followed by all the places in that state. Graphically, this is shown as:

State

County A 

County B 

County C

Place X 

Place Y 

Place Z
Geographic Terms and Concepts A-5

U.S. Census Bureau, 2010 Census Summary File 1

Nation-Based Hierarchies

Exceptions to the standard hierarchical presentation occur for entities that do not necessarily nest within 

states, most notably American Indian, Alaska Native, and Native Hawaiian areas and core based statistical 

areas.

American Indian, Alaska Native, and Native Hawaiian Area (AIANNHA) Hierarchy

Because federally recognized American Indian areas can cross state lines, a separate American Indian, 

Alaska Native, and Native Hawaiian area (AIANNHA) hierarchy exists for these areas. For instance, the 

following American Indian entities can cross state lines: federally recognized American Indian reservations 

and/or off-reservation trust lands, tribal subdivisions, tribal designated statistical areas, tribal census 

tracts, and tribal block groups. National summary data for American Indian reservations or statistical areas 

may be presented as an alphabetical listing of names followed by the state portions of each area. Also, a 

tribal census tract or tribal block group may be located in more than one state or county. Data for tribal 

census tracts and tribal block groups are presented only in Census Bureau products utilizing the AIANNHA 

hierarchy and are not present in products utilizing the standard census geographic hierarchy.

The diagram in Figure A-2 shows geographic relationships among geographic entities in the AIANNHA 

hierarchy. It does not show the geographic levels county, county subdivision, and place, among others, 

because AIANNHAs do not necessarily nest within them.

DEFINITIONS OF GEOGRAPHIC ENTITIES, TERMS, AND CONCEPTS

The definitions below are for geographic entities and concepts that the Census Bureau includes in its 

standard data products. Not all entities, terms, and concepts are shown in any one data product.

AMERICAN INDIAN, ALASKA NATIVE, AND NATIVE HAWAIIAN AREA

There are both legal and statistical American Indian, Alaska Native, and Native Hawaiian areas (AIANNHAs) 

for which the Census Bureau provides data. The legal entities consist of federally recognized American 

Indian reservations and off-reservation trust land areas, the tribal subdivisions that can divide these 

entities, state-recognized American Indian reservations, Alaska Native regional corporations, and Hawaiian 

home lands. The statistical entities are Alaska Native village statistical areas, Oklahoma tribal statistical 

areas, tribal designated statistical areas, and state designated tribal statistical areas. Statistical tribal 

subdivisions can exist within Oklahoma tribal statistical areas. In all cases, these areas are mutually 

exclusive in that no AIANNHA can overlap another tribal entity, except for tribal subdivisions, which by 

definition subdivide some American Indian entities, and Alaska Native village statistical areas, which exist 

within Alaska Native regional corporations. In cases where more than one tribe claims jurisdiction over an 

area, the Census Bureau creates a joint-use area as a separate entity to define this area of dual claims. The 

following provides more detail about each of the various AIANNHAs.

Legal Entities

Alaska Native regional corporations (ANRCs) were created pursuant to the Alaska Native Claims Settlement 

Act (ANCSA) (Pub. L. 92-203, 85 Stat. 688 [1971]; 43 U.S.C. 1602 et seq. [2000]), enacted in 1971 as a 

‘‘Regional Corporation’’ and organized under the laws of the state of Alaska to conduct both the for-profit 

and non-profit affairs of Alaska Natives within a defined region of Alaska. For the Census Bureau, ANRCs 

are considered legal geographic entities. Twelve ANRCs cover the entire state of Alaska except for the 

area within the Annette Island Reserve (a federally recognized American Indian reservation under the 

governmental authority of the Metlakatla Indian Community). A thirteenth ANRC represents Alaska Natives 

who do not live in Alaska and do not identify with any of the twelve corporations. The Census Bureau does 

not provide data for this thirteenth ANRC because it has no defined geographic extent and thus, it does 

not appear in the TIGER/Line® shapefiles. The Census Bureau offers representatives of the 12 nonprofit 

ANRCs in Alaska the opportunity to review and update the ANRC boundaries before each decennial census. 
A-6 Geographic Terms and Concepts

 U.S. Census Bureau, 2010 Cenus Summary File 1

Each ANRC is assigned a five-digit numeric Federal Information Processing Series (FIPS) code and an eightdigit National Standard (ANSI) code.

American Indian reservations—Federal (federal AIRs) are areas that have been set aside by the United 

States for the use of tribes, the exterior boundaries of which are more particularly defined in the final 

tribal treaties, agreements, executive orders, federal statutes, secretarial orders, or judicial determinations. 

The Bureau of Indian Affairs maintains a list of all federally recognized tribal governments and makes 

final determination of the inventory of federal AIRs. The Census Bureau recognizes federal reservations 

(and associated off-reservation trust lands) as territory over which American Indian tribes have primary 

governmental authority. American Indian reservations can be legally described as colonies, communities, 

Indian colonies, Indian communities, Indian rancherias, Indian reservations, Indian villages, pueblos, 

rancherias, ranches, reservations, reserves, settlements, or villages. The Census Bureau contacts 

representatives of American Indian tribal governments to identify the boundaries for federal reservations 

through its annual Boundary and Annexation Survey. Federal reservations may cross state and all other 

area boundaries.

Each federal AIR is assigned a four-digit census code ranging from 0001 through 4799 in alphabetical order 

of AIR names nationwide. This nation-based census code is the primary unique identifier for the AIR. Each 

federal AIR also is assigned a five-digit Federal Information Processing Series (FIPS) code and an eight-digit 

National Standard (ANSI) code. Because FIPS codes are assigned in alphabetical sequence within each state, 

the FIPS code will be different in each state for reservations that include territory in more than one state.

American Indian reservations—State (state AIRs) are reservations established by some state governments 

for tribes recognized by the state. A governor-appointed state liaison provides the names and boundaries 

for state-recognized American Indian reservations to the Census Bureau. State reservations must be 

defined within a single state but may cross county and other types of boundaries. Each state AIR is 

assigned a four-digit census code ranging from 9000 through 9499. Each state AIR also is assigned a fivedigit Federal Information Processing Series (FIPS) code and an eight-digit National Standard (ANSI) code. 

To further identify and differentiate state-recognized American Indian areas from those that are federally 

recognized, the text “(state)” is appended to the AIR name.

American Indian tribal subdivisions, described as additions, administrative areas, areas, chapters, county 

districts, communities, districts, or segments, are legal administrative subdivisions of federally recognized 

American Indian reservations and off-reservation trust lands or are statistical subdivisions of Oklahoma 

tribal statistical areas (OTSAs). These entities are internal units of self-government or administration 

that serve social, cultural, and/or economic purposes for the American Indians on the reservations, offreservation trust lands, or OTSAs. The Census Bureau obtains the boundary and name information for 

tribal subdivisions from tribal governments. Each American Indian tribal subdivision is assigned a threedigit census code that is alphabetically in order and unique within each American Indian area, a five-digit 

Federal Information Processing Series (FIPS) code assigned alphabetically within state, and an eight-digit 

National Standard (ANSI) code. Because FIPS codes are assigned in alphabetical sequence within each state, 

the FIPS code will be different in each state for tribal subdivisions that include territory in more than one 

state. All the summary levels that include tribal subdivisions in the presentation hierarchy will only have 

records for the 24 American Indian areas and two OTSAs that actually have tribal subdivisions. The list of 

areas and four-digit census codes is:

Hawaiian home lands (HHLs) are areas held in trust for Native Hawaiians by the state of Hawaii, pursuant 

to the Hawaiian Homes Commission Act of 1920, as amended. The Census Bureau obtains the names 

and boundaries for HHLs from state officials. The names of the home lands are based on the traditional 

ahupua‘a names of the Crown and government lands of the Kingdom of Hawaii from which the lands were 

designated or from the local name for an area. Being lands held in trust, HHLs are treated as equivalent to 

off-reservation trust land areas with the American Indian Trust Land/Hawaiian Home Land Indicator coded 

as “T.” Each HHL is assigned a national four-digit census code ranging from 5000 through 5499 based on 

the alphabetical sequence of each HHL name, a five-digit Federal Information Processing Series (FIPS) code 

in alphabetical order within the state of Hawaii, and an eight-digit National Standard (ANSI) code.

Joint-use areas, as applied to any American Indian area by the Census Bureau, means an area that is 

administered jointly and/or claimed by two or more American Indian tribes. The Census Bureau designates 

legal joint-use areas as unique geographic entities equivalent to a reservation for the purpose of 

presenting statistical data. Each is assigned a national four-digit census code ranging from 4800 through 

4999 based on the alphabetical sequence of each joint-use area name, a five-digit Federal Information 

Processing Series (FIPS) code in alphabetical order within state, and an eight-digit National Standard (ANSI) 

code. No joint-use areas exist in multiple states.

Off-reservation trust lands are areas for which the United States holds title in trust for the benefit of a 

tribe (tribal trust land) or for an individual American Indian (individual trust land). Trust lands can be 

alienated or encumbered only by the owner with the approval of the Secretary of the Interior or his/her 

authorized representative. Trust lands may be located on or off a reservation; however, the Census Bureau 

tabulates data only for off-reservation trust lands with the off-reservation trust lands always associated 

with a specific federally recognized reservation and/or tribal government. As for federally recognized 

reservations, the Census Bureau obtains the boundaries of off-reservation trust lands from American Indian 
A-8 Geographic Terms and Concepts

 U.S. Census Bureau, 2010 Census Summary File 1

tribal governments through its annual Boundary and Annexation Survey. The Census Bureau recognizes 

and tabulates data for reservations and off-reservation trust lands because American Indian tribes have 

primary governmental authority over these lands. The Census Bureau does not identify fee land (or land in 

fee simple status) or restricted fee lands as specific geographic areas.

Off-reservation trust lands are assigned a four-digit census code, a five-digit Federal Information 

Processing Series (FIPS) code, and an eight-digit National Standard (ANSI) code that is the same as that 

for the reservation with which they are associated. Trust lands associated with tribes that do not have a 

reservation are assigned unique codes. The census code is assigned by tribal name within the range 0001 

through 4799, interspersed alphabetically among the reservation names. Because FIPS codes are assigned 

in alphabetical sequence within each state, the FIPS code will be different in each state for off-reservation 

trust lands that include territory in more than one state. In decennial census data tabulations, the 

American Indian Trust Land/Hawaiian Home Land Indicator uniquely identifies off-reservation trust lands, 

as well as reservation or statistical area only portions, Hawaiian home lands, and records that consist of 

the combination of reservation and off-reservation trust land territory.

Statistical Entities

Alaska Native village statistical areas (ANVSAs) represent the more densely settled portion of Alaska 

Native villages (ANVs). The ANVs constitute associations, bands, clans, communities, groups, tribes, or 

villages recognized pursuant to the Alaska Native Claims Settlement Act of 1971 (Public Law 92-203). 

Because ANVs do not have boundaries that are easy to locate, the Census Bureau does not delimit ANVs. 

Instead, the Census Bureau presents statistical data for ANVSAs that represent the settled portion of 

ANVs. In addition, each ANVSA should include only an area where Alaska Natives, especially members of 

the defining ANV, represent a substantial proportion of the population during at least one season of the 

year. ANVSAs are delineated or reviewed by officials of the ANV or, if no ANV official chose to participate 

in the delineation process, officials of the Alaska Native Regional Corporation (ANRC) in which the ANV is 

located. An ANVSA may not overlap the boundary of another ANVSA or an American Indian reservation. 

Each ANVSA is alphabetically assigned a national four-digit census code ranging from 6000 through 7999, 

an alphabetically assigned state-based five-digit Federal Information Processing Series (FIPS) code, and an 

eight-digit National Standard (ANSI) code.

Oklahoma tribal statistical areas (OTSAs) are statistical entities identified and delineated by the Census 

Bureau in consultation with federally recognized American Indian tribes that had a former reservation 

in Oklahoma. The boundary of an OTSA will be that of the former reservation in Oklahoma, except 

where modified by agreements with neighboring tribes for statistical data presentation purposes. Each 

OTSA is alphabetically assigned a national four-digit census code ranging from 5500 through 5899, an 

alphabetically assigned state-based five-digit Federal Information Processing Series (FIPS) code, and an 

eight-digit National Standard (ANSI) code. Tribal subdivisions are allowed within OTSAs and exist for the 

2010 Census in the Cherokee and Choctaw OTSAs.

Oklahoma tribal statistical area (OTSA) Joint-Use Areas, as applied to OTSAs by the Census Bureau, means 

an area that is administered jointly and/or claimed by two or more American Indian tribes that have a 

delineated OTSA. The Census Bureau designates statistical joint-use areas as unique geographic entities 

for the purpose of presenting statistical data. Only Oklahoma tribal statistical areas have statistical jointuse areas. Each Oklahoma tribal joint-use area is alphabetically assigned a national four-digit census code 

ranging from 5900 through 5999, an alphabetically assigned state-based five-digit Federal Information 

Processing Series (FIPS) code, and an eight-digit National Standard (ANSI) code.

State designated tribal statistical areas (SDTSAs—referred to as State Designated American Indian 

Statistical Areas for Census 2000) are statistical entities for state-recognized American Indian tribes 

that do not have a state-recognized land base (reservation). SDTSAs are identified and delineated for 

the Census Bureau by a state liaison identified by the governor’s office in each state. SDTSAs generally 

encompass a compact and contiguous area that contains a concentration of people who identify with a 
Geographic Terms and Concepts A-9

U.S. Census Bureau, 2010 Census Summary File 1

state-recognized American Indian tribe and in which there is structured or organized tribal activity. An 

SDTSA may not be located in more than one state and it may not include area within any other American 

Indian, Alaska Native, or Native Hawaiian area. Each SDTSA is alphabetically assigned a four-digit 

census code ranging from 9500 through 9998, an alphabetically assigned state-based five-digit Federal 

Information Processing Series (FIPS) code, and an eight-digit National Standard (ANSI) code.

Tribal designated statistical areas (TDSAs) are statistical entities identified and delineated for the Census 

Bureau by federally recognized American Indian tribes that do not currently have a federally recognized 

land base (reservation or off-reservation trust land). A TDSA generally encompasses a compact and 

contiguous area that contains a concentration of individuals who identify with a federally recognized 

American Indian tribe and in which there is structured or organized tribal activity. A TDSA may be 

located in more than one state (although none do for 2010), but it may not include area within any other 

American Indian, Alaska Native, or Native Hawaiian area. Each TDSA is alphabetically assigned a four-digit 

census code ranging from 8000 through 8999, an alphabetically assigned state-based five-digit Federal 

Information Processing Series (FIPS) code, and an eight-digit National Standard (ANSI) code.

American Indian, Alaska Native, and Native Hawaiian Area (AIANNHA) Codes—AIANNHAs are 

represented in Census Bureau products using a national four-character numeric census code field and a 

single alphabetic character American Indian trust land/Hawaiian home land indicator field. The census 

codes are assigned in alphabetical order in assigned ranges by AIANNHA type nationwide, except that 

joint-use areas appear at the end of the code range. Off-reservation trust lands are assigned the same code 

as the reservation with which they are associated. Trust lands associated with tribes that do not have a 

reservation are assigned codes based on tribal name. Federal Information Processing Series (FIPS) codes for 

all AIANNHAs range from 00001 through 89999, without differentiation among the many types of areas. 

The type of AIANNHA can be identified either by the census code or by the FIPS class code. The range 

of census codes allocated to each AIANNHA and the valid FIPS class code(s) associated with each are as

AREA MEASUREMENT

Area measurement data provide the size, in square units (metric and nonmetric) of geographic entities for 

which the Census Bureau tabulates and disseminates data. Area is calculated from the specific boundary 
A-10 Geographic Terms and Concepts

 U.S. Census Bureau, 2010 Census Summary File 1

recorded for each entity in the Census Bureau’s geographic database (see “MAF/TIGER Database”). The 

Census Bureau provides area measurement data for both land area and water area. The water area 

figures include inland, coastal, Great Lakes, and territorial sea water. Inland water consists of any lake, 

reservoir, pond, or similar body of water that is recorded in the Census Bureau’s geographic database. It 

also includes any river, creek, canal, stream, or similar feature that is recorded in that database as a twodimensional feature (rather than as a single line). The portions of the oceans and related large embayments 

(such as Chesapeake Bay and Puget Sound), the Gulf of Mexico, and the Caribbean Sea that belong to the 

United States and its territories are classified as coastal and territorial waters; the Great Lakes are treated 

as a separate water entity. Rivers and bays that empty into these bodies of water are treated as inland 

water from the point beyond which they are narrower than 1 nautical mile across. Identification of land 

and inland, coastal, territorial, and Great Lakes waters is for data presentation purposes only and does not 

necessarily reflect their legal definitions.

Land and water area measurements may disagree with the information displayed on Census Bureau 

maps and in the MAF/TIGER database because, for area measurement purposes, hydrologic features 

identified as intermittent water, glacier, or swamp are reported as land area. The water area measurement 

reported for some geographic entities includes water that is not included in any lower-level geographic 

entity. Therefore, because water is contained only in a higher-level geographic entity, summing the water 

measurements for all the component lower-level geographic entities will not yield the water area of that 

higher-level entity. This occurs, for example, where water is associated with a county but is not within 

the legal boundary of any county subdivision. The accuracy of any area measurement data is limited by 

the accuracy inherent in 1) the location and shape of the various boundary information in the MAF/TIGER 

database, 2) the identification, and classification of water bodies coupled with the location and shapes of 

the shorelines of water bodies in that database, and 3) rounding affecting the last digit in all operations 

that compute and/or sum the area measurements.

BLOCK

Blocks (Census Blocks) are statistical areas bounded by visible features, such as streets, roads, streams, 

and railroad tracks, and by nonvisible boundaries, such as selected property lines and city, township, 

school district, and county limits and short line-of-sight extensions of streets and roads. Generally, census 

blocks are small in area; for example, a block in a city bounded on all sides by streets. Census blocks in 

suburban and rural areas may be large, irregular, and bounded by a variety of features, such as roads, 

streams, and transmission lines. In remote areas, census blocks may encompass hundreds of square miles. 

Census blocks cover the entire territory of the United States, Puerto Rico, and the Island Areas. Census 

blocks nest within all other tabulated census geographic entities and are the basis for all tabulated data.

Census Block Numbers—Census blocks are numbered uniquely with a four-digit census block number 

from 0000 to 9999 within census tract, which nest within state and county. The first digit of the census 

block number identifies the block group. Block numbers beginning with a zero (in Block Group 0) are only 

associated with water-only areas.

BLOCK GROUP

Block Groups (BGs) are statistical divisions of census tracts, are generally defined to contain between 

600 and 3,000 people, and are used to present data and control block numbering. A block group consists 

of clusters of blocks within the same census tract that have the same first digit of their four-digit census 

block number. For example, blocks 3001, 3002, 3003, . . ., 3999 in census tract 1210.02 belong to BG 

3 in that census tract. Most BGs were delineated by local participants in the Census Bureau’s Participant 

Statistical Areas Program. The Census Bureau delineated BGs only where a local or tribal government 

declined to participate, and a regional organization or State Data Center was not available to participate. 

A BG usually covers a contiguous area. Each census tract contains at least one BG, and BGs are uniquely 

numbered within the census tract. Within the standard census geographic hierarchy, BGs never cross state, 

county, or census tract boundaries but may cross the boundaries of any other geographic entity. Tribal 
Geographic Terms and Concepts A-11

U.S. Census Bureau, 2010 Census Summary File 1

census tracts and tribal BGs are separate and unique geographic areas defined within federally recognized 

American Indian reservations and can cross state and county boundaries (see “Tribal Census Tract” and 

“Tribal Block Group”). The tribal census tracts and tribal block groups may be completely different from the 

census tracts and block groups defined by state and county.

Block Group Codes—BGs have a valid code range of 0 through 9. BGs beginning with a zero only contain 

water area and are generally in coastal and Great Lakes water and territorial seas, but also in larger inland 

water bodies. For the 2010 Census, a block group 0 for the water portion can be delineated in any census 

tract and not just those census tracts also defined to only include water area. This is a change from Census 

2000, when block groups coded 0 only existed in census tracts with a code of 0. To differentiate between 

county-based block groups and tribal block groups, the codes for tribal block groups use an alphabetic 

character (see “Tribal Block Group”).

BOUNDARY CHANGES

Many of the legal and statistical entities for which the Census Bureau tabulates decennial census data have 

had boundary changes between Census 2000 and the 2010 Census; that is, between January 1, 2000, and 

January 1, 2010. Boundary changes to legal entities result from:

1. Annexations to or detachments from legally established governmental units.

2. Mergers or consolidations of two or more governmental units.

3. Establishment of new governmental units.

4. Disincorporations or disorganizations of existing governmental units.

5. Changes in treaties or executive orders and governmental action placing additional lands in trust.

6. Decisions by federal, state, and local courts.

7. Redistricting for congressional districts and state legislative districts.

8. Ancillary changes to legal or statistical areas as a result of annexations and detachments; for example, 

reduction of territory for a census designated place as the result of an annexation by an adjacent 

incorporated place.

9. Changes to correct errors or more accurately place boundaries relative to visible features.

10. Changes to statistical areas as the result of concept or criteria changes.

All legal boundaries used for the 2010 Census are those reported to the Census Bureau to be in effect as 

of January 1, 2010. The statistical area boundaries also reflect a January 1, 2010, date for delineation. 

The legal boundaries are collected through various surveys and programs: the Boundary and Annexation 

Survey, Redistricting Data Program, and the School District Review Program. There is a Geographic Change 

User Note Indicator in data files that identifies entities for which there have been changes to boundaries or 

data attributes (for example, legal/statistical area description or code) between the two censuses.

Statistical entity boundaries generally are reviewed by local, state, or tribal governments and can have 

changes to adjust boundaries to visible features to better define the geographic area each encompasses or 

to account for shifts and changes in the population distribution within an area. Where statistical areas have 

a relationship to legal area boundaries, complementary updates occur; for example, removing territory 

from a census designated place if annexed to an incorporated place or contracting a tribal designated 

statistical area if the area is added to an American Indian reservation.

The historical counts shown for states, counties, county subdivisions, places, American Indian, Alaska 

Native, and Native Hawaiian areas, and other areas are not updated for boundary changes and thus, reflect 

the population and housing units in each entity as delineated at the time of each decennial census.

CENSUS DIVISION

Census Divisions are groupings of states and the District of Columbia that are subdivisions of the four 

census regions (see “Census Region”). There are nine census divisions, and each is identified by a singledigit census code. Puerto Rico and the Island Areas are not part of any census region or census division. 

For a list of all census regions, census divisions, and their constituent states, see Figure A-3.

CENSUS REGION

Census Regions are groupings of states and the District of Columbia that subdivide the United States 

for the presentation of census data. There are four census regions—Northeast, Midwest, South, and West. 

Each of the four census regions is divided into two or more census divisions (see “Census Division”). 

Each census region is identified by a single-digit census code. Puerto Rico and the Island Areas are not 

part of any census region or census division. For a list of all census regions, census divisions, and their 

constituent states, see Figure A-3.

CENSUS TRACT

Census Tracts are small, relatively permanent statistical subdivisions of a county or equivalent entity that 

are updated by local participants prior to each decennial census as part of the Census Bureau’s Participant 

Statistical Areas Program. The Census Bureau delineates census tracts in situations where no local 

participant existed or where state, local, or tribal governments declined to participate. The primary purpose 

of census tracts is to provide a stable set of geographic units for the presentation of statistical data. 

Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 

4,000 people. A census tract usually covers a contiguous area; however, the spatial size of census tracts 

varies widely depending on the density of settlement. Census tract boundaries are delineated with the 

intention of being maintained over a long time so that statistical comparisons can be made from census to 

census. Census tracts occasionally are split due to population growth or merged as a result of substantial 

population decline.

Census tract boundaries generally follow visible and identifiable features. They may follow nonvisible 

legal boundaries, such as minor civil division (MCD) or incorporated place boundaries in some states 

and situations, to allow for census-tract-to-governmental-unit relationships where the governmental 

boundaries tend to remain unchanged between censuses. State and county boundaries always are census 

tract boundaries in the standard census geographic hierarchy. Tribal census tracts are a unique geographic 

entity defined within federally recognized American Indian reservations and off-reservation trust lands and 

can cross state and county boundaries. Tribal census tracts may be completely different from the census 

tracts and block groups defined by state and county (see “Tribal Census Tract”).

Census Tract Codes and Numbers—Census tracts are identified by an up to four-digit integer number 

and may have an optional two-digit suffix; for example 1457.02 or 23. The census tract codes consist of 

six digits with an implied decimal between the fourth and fifth digit corresponding to the basic census 

tract number but with leading zeroes and trailing zeroes for census tracts without a suffix. The tract 

number examples above would have codes of 145702 and 002300, respectively.

Some ranges of census tract numbers in the 2010 Census are used to identify distinctive types of census 

tracts. The code range in the 9400s is used for those census tracts with a majority of population, housing, 

or land area associated with an American Indian area and matches the numbering used in Census 2000. 

The code range in the 9800s is new for 2010 and is used to specifically identify special land-use census 

tracts; that is, census tracts defined to encompass a large area with little or no residential population 

with special characteristics, such as large parks or employment areas. The range of census tracts in the 

9900s represents census tracts delineated specifically to cover large bodies of water. This is different from 

Census 2000 when water-only census tracts were assigned codes of all zeroes (000000); 000000 is no 

longer used as a census tract code for the 2010 Census.
Geographic Terms and Concepts A-13

U.S. Census Bureau, 2010 Census Summary File 1

The Census Bureau uses suffixes to help identify census tract changes for comparison purposes. Census 

tract suffixes may range from .01 to .98. As part of local review of existing census tracts before each 

census, some census tracts may have grown enough in population size to qualify as more than one census 

tract. When a census tract is split, the split parts usually retain the basic number but receive different 

suffixes. For example, if census tract 14 is split, the new tract numbers would be 14.01 and 14.02. In a 

few counties, local participants request major changes to, and renumbering of, the census tracts; however, 

this is generally discouraged. Changes to individual census tract boundaries usually do not result in 

census tract numbering changes. 

Tribal Census Tracts in American Indian Areas—The Census Bureau introduced the concept of tribal 

census tracts for the first time for Census 2000. Tribal census tracts for that census consisted of the 

standard county-based census tracts tabulated within American Indian areas, thus allowing for the tracts 

to ignore state and county boundaries for tabulation. The Census Bureau assigned the 9400 range of 

numbers to identify specific tribal census tracts; however, not all tribal census tracts used this numbering 

scheme. For the 2010 Census, tribal census tracts no longer are tied to or numbered in the same way as 

the county-based census tracts (see “Tribal Census Tract”).

CODES FOR GEOGRAPHIC ENTITIES

The Census Bureau and other federal agencies assign codes to geographic entities to facilitate the 

organization, presentation, and exchange of statistical data and other information. Geographic entity codes 

allow for the unambiguous identification of individual entities, generally within a specific, higher-level 

geographic entity (for example, county codes are assigned uniquely within each state). For geographic 

entities that have names (such as states, counties, places, county subdivisions, urban areas, and 

metropolitan and micropolitan statistical areas), codes generally are assigned alphabetically based on name.

Census Bureau data products contain several types of geographic entity codes: Federal Information 

Processing Series (FIPS), American National Standards Institute (ANSI), and Census Bureau codes.

Federal Information Processing Series (FIPS)—These are codes formerly known as Federal Information 

Processing Standards codes, until the National Institute of Standards and Technology (NIST) announced 

its decision in 2005 to remove geographic entity codes from its oversight. The Census Bureau continues 

to maintain and issue codes for geographic entities covered under FIPS oversight, albeit with a revised 

meaning for the FIPS acronym. Geographic entities covered under FIPS include states, counties, 

congressional districts, core based statistical areas, places, county subdivisions, subminor civil divisions, 

consolidated cities, and all types of American Indian, Alaska Native, and Native Hawaiian areas. FIPS codes 

are assigned alphabetically according to the name of the geographic entity and may change to maintain 

alphabetic sort when new entities are created or names change. FIPS codes for specific geographic 

entity types are usually unique within the next highest level of geographic entity with which a nesting 

relationship exists. For example, FIPS state, congressional district, and core based statistical area codes are 

unique within nation; FIPS county, place, county subdivision, and subminor civil division codes are unique 

within state. The codes for American Indian, Alaska Native, and Native Hawaiian areas also are unique 

within state; those areas in multiple states will have different codes for each state.

American National Standards Institute (ANSI)—With the removal of geographic entities from Federal 

Information Processing Standards oversight, the Census Bureau and other federal agencies have sought 

American National Standards Institute (ANSI) oversight authority for geographic entity codes. These codes 

are referred to as “National Standard” codes in some Census Bureau products. Geographic entities covered 

under ANSI include states, counties, congressional districts, core based statistical areas and related 

statistical areas, places, county subdivisions, consolidated cities, subminor civil divisions, and all types of 

American Indian, Alaska Native, and Native Hawaiian areas—Alaska Native regional corporations, Alaska 

Native village statistical areas, American Indian reservation and off-reservation trust lands, American 

Indian tribal subdivisions, Hawaiian home lands, Oklahoma tribal statistical areas, state designated tribal 

statistical areas, and tribal designated statistical areas.
A-14 Geographic Terms and Concepts

 U.S. Census Bureau, 2010 Census Summary File 1

Relationship between FIPS and ANSI codes—Geographic entities for which NIST formerly provided Federal 

Information Processing Standards oversight will continue to be referred to as FIPS (Federal Information 

Processing Series) codes in some Census Bureau data products, despite the Census Bureau having sought 

ANSI oversight authority. These geographic entities include states, counties, congressional districts, and 

core based statistical areas and related statistical areas. The Census Bureau continues to maintain and 

issue codes for these entities following the same structure and without change to existing codes, except 

when necessary to maintain alphabetic sorting based on names of entities. The Census Bureau also 

continues to maintain and issue five-digit FIPS codes (formerly FIPS 55) for places, county subdivisions, 

consolidated cities, subminor civil divisions, Alaska Native Regional Corporations, and all types of 

American Indian, Alaska Native, and Native Hawaiian areas but is not seeking ANSI oversight authority 

for these entity codes. The U.S. Geological Survey has ANSI oversight authority for its Geographic Names 

Information System identifier (GNIS ID), which has been adopted as a National Standard (NS) code for 

states, counties, places, county subdivisions, subminor civil divisions, consolidated cities, Alaska Native 

Regional Corporations, and all types of American Indian, Alaska Native, and Native Hawaiian areas. The 

Census Bureau will include the GNIS ID for these entities in its data products, portrayed as an eight-digit 

character numeric code and identified as “ANSI.” NS codes (GNIS IDs) will not sort geographic entities in 

alphabetical order based on name or title, as is the case with FIPS codes.

Census Bureau codes—The Census Bureau assigns and issues codes for a number of geographic entities for 

which FIPS or ANSI codes are not available, and sometimes in addition to FIPS and ANSI codes. Geographic 

entities for which census codes are assigned and issued in Census Bureau data products include regions, 

divisions, census tracts, block groups, census blocks, urban areas, and all types of American Indian, 

Alaska Native, and Native Hawaiian areas. Some codes—voting district, state legislative district, and school 

district—use standards established by the states—or for school districts, the U.S. Department of Education.

CONGRESSIONAL DISTRICT

Congressional Districts are the 435 areas from which people are elected to the U.S. House of 

Representatives. After the apportionment of congressional seats among the states based on decennial 

census population counts, each state with multiple seats is responsible for establishing congressional 

districts for the purpose of electing representatives. Each congressional district is to be as equal in 

population to all other congressional districts in a state as practicable. For the District of Columbia, Puerto 

Rico, and each Island Area, a separate code is used to identify the entire areas of these state-equivalent 

entities as having a single nonvoting delegate.

Congressional District Codes—Congressional districts are identified by a two-character numeric Federal 

Information Processing Series (FIPS) code numbered uniquely within state. The District of Columbia, Puerto 

Rico, and the Island Areas have code 98 assigned identifying their nonvoting delegate status with respect 

to representation in Congress:

01 to 53—Congressional district codes

00—At large (single district for state)

98—Nonvoting delegate

CONSOLIDATED CITY

Consolidated City—A consolidated government is a unit of local government for which the functions of 

an incorporated place and its county or minor civil division (MCD) have merged. This action results in both 

the primary incorporated place and the county or MCD continuing to exist as legal entities, even though 

the county or MCD performs few or no governmental functions and has few or no elected officials. Where 

this occurs—and where one or more other incorporated places in the county or MCD continue to function 

as separate governments, even though they have been included in the consolidated government—

the primary incorporated place is referred to as a consolidated city. The Census Bureau classifies the 
Geographic Terms and Concepts A-15

U.S. Census Bureau, 2010 Census Summary File 1

separately incorporated places within the consolidated city as place entities and creates a separate place 

(balance) record for the portion of the consolidated city not within any other place. 

Consolidated City (Balance) Portions refer to the areas of a consolidated city not included in another 

separately incorporated place. For example, Butte-Silver Bow, MT, is a consolidated city (former Butte city 

and Silver Bow County) that includes the separately incorporated municipality of Walkerville city. The area 

of the consolidated city that is not in Walkerville city is assigned to Butte-Silver Bow (balance). The name 

always includes the “(balance)” identifier (see “Place”).

CORE BASED STATISTICAL AREAS AND RELATED STATISTICAL AREAS

Core Based Statistical Areas (CBSAs) consist of the county or counties or equivalent entities associated 

with at least one core (urbanized area or urban cluster) of at least 10,000 population, plus adjacent 

counties having a high degree of social and economic integration with the core as measured through 

commuting ties with the counties associated with the core. The general concept of a CBSA is that of a 

core area containing a substantial population nucleus, together with adjacent communities having a high 

degree of economic and social integration with that core. The term “core based statistical area” became 

effective in 2003 and refers collectively to metropolitan statistical areas and micropolitan statistical areas. 

The U.S. Office of Management and Budget (OMB) defines CBSAs to provide a nationally consistent set of 

geographic entities for the United States and Puerto Rico for use in tabulating and presenting statistical 

data. Current CBSAs are based on application of the 2000 standards (published in the Federal Register of 

December 27, 2000) with Census 2000 data. The first set of areas defined based on the 2000 standards 

were announced on June 6, 2003; subsequent updates have been made to the universe of CBSAs and 

related statistical areas. No CBSAs are defined in the Island Areas. Statistical areas related to CBSAs include 

metropolitan divisions, combined statistical areas (CSAs), New England city and town areas (NECTAs), 

NECTA divisions, and combined NECTAs.

Combined New England City and Town Areas (Combined NECTAs) consist of two or more adjacent 

New England city and town areas (NECTAs) that have substantial employment interchange. The NECTAs 

that combine to create a combined NECTA retain separate identities within the larger combined NECTA. 

Because combined NECTAs represent groupings of NECTAs, they should not be ranked or compared with 

individual NECTAs.

Combined Statistical Areas (CSAs) consist of two or more adjacent CBSAs that have substantial 

employment interchange. The CBSAs that combine to create a CSA retain separate identities within the 

larger CSA. Because CSAs represent groupings of metropolitan and/or micropolitan statistical areas, they 

should not be ranked or compared with individual metropolitan and micropolitan statistical areas.

Metropolitan Divisions are smaller groupings of counties or equivalent entities defined within a 

metropolitan statistical area containing a single core with a population of at least 2.5 million. Not all 

metropolitan statistical areas with urbanized areas of this size will contain metropolitan divisions. A 

metropolitan division consists of one or more main/secondary counties that represent an employment 

center or centers, plus adjacent counties associated with the main/secondary county or counties through 

commuting ties. Because metropolitan divisions represent subdivisions of larger metropolitan statistical 

areas, it is not appropriate to rank or compare metropolitan divisions with metropolitan and micropolitan 

statistical areas. It would be appropriate to rank and compare metropolitan divisions.

Metropolitan Statistical Areas are CBSAs associated with at least one urbanized area that has a 

population of at least 50,000. The metropolitan statistical area comprises the central county or counties or 

equivalent entities containing the core, plus adjacent outlying counties having a high degree of social and 

economic integration with the central county or counties as measured through commuting.

Micropolitan Statistical Areas are CBSAs associated with at least one urban cluster that has a 

population of at least 10,000 but less than 50,000. The micropolitan statistical area comprises the central 

county or counties or equivalent entities containing the core, plus adjacent outlying counties having a 
A-16 Geographic Terms and Concepts

 U.S. Census Bureau, 2010 Census Summary File 1

high degree of social and economic integration with the central county or counties as measured through 

commuting.

New England City and Town Areas (NECTAs) are an alternative set of geographic entities, similar in 

concept to the county-based CBSAs defined nationwide, that OMB defines in New England based on county 

subdivisions—usually cities and towns. NECTAs are defined using the same criteria as county-based CBSAs, 

and, similar to CBSAs, NECTAs are categorized as metropolitan or micropolitan.

New England City and Town Area (NECTA) Divisions are smaller groupings of cities and towns 

defined within a NECTA containing a single core with a population of at least 2.5 million. A NECTA division 

consists of a main city or town that represents an employment center, plus adjacent cities and towns 

associated with the main city or town through commuting ties. Each NECTA division must contain a total 

population of 100,000 or more. Because NECTA divisions represent subdivisions of larger NECTAs, it is 

not appropriate to rank or compare NECTA divisions with NECTAs. It would be appropriate to rank and 

compare NECTA divisions.

Principal Cities of a CBSA (or NECTA) include the largest incorporated place with a population of at 

least 10,000 in the CBSA, or if no incorporated place of at least 10,000 population is present in the CBSA, 

the largest incorporated place or census designated place (CDP) in the CBSA. Principal cities also include 

any additional incorporated place or CDP with a population of at least 250,000 or in which 100,000 or 

more persons work; any additional incorporated place or CDP with a population of at least 50,000 and 

in which the number of jobs meets or exceeds the number of employed residents; and any additional 

incorporated place or CDP with a population of at least 10,000 but less than 50,000 and at least one-third 

the population size of the largest place and in which the number of jobs meets or exceeds the number of 

employed residents. Note that there are some places designated as principal cities of NECTAs that are not 

principal cities of a CBSA. 

Core Based Statistical Area Codes—Metropolitan statistical areas, micropolitan statistical areas, 

NECTAs, metropolitan divisions, and NECTA divisions are identified using a five-digit numeric code that is 

assigned alphabetically based on title and is unique within the nation. The combined statistical area and 

combined NECTAs are identified using a three-digit numeric code, also assigned alphabetically based on 

title and unique within the nation. Codes, length, and ranges are:

CBSA entity Length Range*

Metropolitan statistical area . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Five digits 10000–49999

Combined NECTA . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Three digits 700–799

* Metropolitan divisions and NECTA divisions are distinguished from metropolitan and micropolitan statistical areas and NECTAs by 

codes that end in “4.” Metropolitan and micropolitan statistical areas and NECTAs cannot end in “4.”

COUNTY OR STATISTICALLY EQUIVALENT ENTITY

The primary legal divisions of most states are termed counties. In Louisiana, these divisions are known as 

parishes. In Alaska, which has no counties, the equivalent entities are the organized boroughs, city and 

boroughs, municipalities, and census areas; the latter of which are delineated cooperatively for statistical 

purposes by the state of Alaska and the Census Bureau. In four states (Maryland, Missouri, Nevada, and 

Virginia), there are one or more incorporated places that are independent of any county organization and 

thus constitute primary divisions of their states. These incorporated places are known as independent 

cities and are treated as equivalent entities for purposes of data presentation. The District of Columbia 

and Guam have no primary divisions, and each area is considered an equivalent entity for purposes of 
Geographic Terms and Concepts A-17

U.S. Census Bureau, 2010 Census Summary File 1

data presentation. All of the counties in Connecticut and Rhode Island and nine counties in Massachusetts 

were dissolved as functioning governmental entities; however, the Census Bureau continues to present 

data for these historical entities in order to provide comparable geographic units at the county level of 

the geographic hierarchy for these states and represents them as nonfunctioning legal entities in data 

products. The Census Bureau treats the following entities as equivalents of counties for purposes of data 

presentation: municipios in Puerto Rico, districts and islands in American Samoa, municipalities in the 

Commonwealth of the Northern Mariana Islands, and islands in the U.S. Virgin Islands. Each county or 

statistically equivalent entity is assigned a three-character numeric Federal Information Processing Series 

(FIPS) code based on alphabetical sequence that is unique within state and an eight-digit National Standard 

feature identifier.

COUNTY SUBDIVISION

County Subdivisions are the primary divisions of counties and equivalent entities. They include 

census county divisions, census subareas, minor civil divisions, and unorganized territories and can be 

classified as either legal or statistical. Each county subdivision is assigned a five-character numeric Federal 

Information Processing Series (FIPS) code based on alphabetical sequence within state and an eight-digit 

National Standard feature identifier.

Legal Entities

Minor civil divisions (MCDs) are the primary governmental or administrative divisions of a county in many 

states (parishes in Louisiana) and the county equivalents in Puerto Rico and the Island Areas. MCDs in 

the United States, Puerto Rico, and the Island Areas represent many different kinds of legal entities with a 

wide variety of governmental and/or administrative functions. MCDs include areas variously designated 

as barrios, barrios-pueblo, boroughs, charter townships, commissioner districts, election districts, election 

precincts, gores, grants, locations, magisterial districts, parish governing authority districts, plantations, 

purchases, reservations, supervisor’s districts, towns, and townships. The Census Bureau recognizes MCDs 

in 29 states, Puerto Rico, and the Island Areas. The District of Columbia has no primary divisions and is 

considered equivalent to an MCD for statistical purposes. (It is also considered a state equivalent and a 

county equivalent.) The 29* states in which MCDs are recognized are:

Arkansas Michigan Ohio

Connecticut Minnesota Pennsylvania

Illinois Mississippi Rhode Island

Indiana Missouri South Dakota

Iowa Nebraska Tennessee

Kansas New Hampshire Vermont

Louisiana New Jersey Virginia

Maine New York West Virginia

Maryland North Carolina Wisconsin

Massachusetts North Dakota

* Tennessee, a state with statistical census county divisions (CCDs) in 2000, reverted to MCDs in 2008.

In some states, all or some incorporated places are not part of any MCD; these places are termed 

independent places. Independent places also serve as primary legal subdivisions and have a Federal 

Information Processing Series (FIPS) county subdivision code and National Standard (ANSI) code that is 

the same as the FIPS and ANSI place code. In nine states—Maine, Massachusetts, New Hampshire, New 

Jersey, North Dakota, Pennsylvania, Rhode Island, South Dakota, and Wisconsin—all incorporated places 

are independent places. In other states, incorporated places are part of, or dependent within, the MCDs in 

which they are located, or the pattern is mixed—some incorporated places are independent of MCDs and 

others are included within one or more MCDs.

The MCDs in 12 states (Connecticut, Maine, Massachusetts, Michigan, Minnesota, New Hampshire, New 

Jersey, New York, Pennsylvania, Rhode Island, Vermont, and Wisconsin) also serve as general-purpose 
A-18 Geographic Terms and Concepts

 U.S. Census Bureau, 2010 Census Summary File 1

local governments that can perform the same governmental functions as incorporated places. The Census 

Bureau presents data for these MCDs in all data products for which place data are provided. 

In New York and Maine, American Indian reservations (AIRs) generally exist outside the jurisdiction of any 

town (MCD) and thus also serve as the equivalent of MCDs for purposes of data presentation.

In states with MCDs, the Census Bureau assigns a default FIPS county subdivision code of 00000 and ANSI 

code of eight zeroes in some coastal, territorial sea, and Great Lakes water where county subdivisions do 

not legally extend into the Great Lakes or out to the 3-mile limit.

Statistical Entities 

Census county divisions (CCDs) are areas delineated by the Census Bureau in cooperation with state, tribal, 

and local officials for statistical purposes. CCDs have no legal function and are not governmental units. 

CCD boundaries usually follow visible features and usually coincide with census tract boundaries. The 

name of each CCD is based on a place, county, or well-known local name that identifies its location. CCDs 

exist where:

1. There are no legally established MCDs.

2. The legally established MCDs do not have governmental or administrative purposes.

3. The boundaries of the MCDs change frequently.

4. The MCDs are not generally known to the public.

CCDs exist within the following 20* states:

Alabama Hawaii Oregon

Arizona Idaho South Carolina

California Kentucky Texas

Colorado Montana Utah

Delaware Nevada Washington

Florida New Mexico Wyoming

Georgia Oklahoma

* Tennessee, a CCD state in 2000, reverted to a MCD state in 2008.

Census subareas are statistical subdivisions of boroughs, city and boroughs, municipalities, and census 

areas, all of which are statistical equivalent entities for counties in Alaska. The state of Alaska and the 

Census Bureau cooperatively delineate the census subareas to serve as the statistical equivalents of MCDs. 

Unorganized territories (UTs) are defined by the Census Bureau in nine MCD states where portions of 

counties or equivalent entities are not included in any legally established MCD or incorporated place. The 

Census Bureau recognizes such separate pieces of territory as one or more separate county subdivisions 

for census purposes. It assigns each unorganized territory a descriptive name, followed by the designation 

“UT” and a county subdivision FIPS and ANSI code. The following states have unorganized territories:

Arkansas Maine North Carolina

Indiana Minnesota North Dakota

Iowa New York South Dakota

GEOGRAPHIC AREA ATTRIBUTES

The Census Bureau collects and maintains information describing selected attributes and characteristics of 

geographic areas. These attributes are Federal Information Processing Series (FIPS) class code, functional 

status, legal/statistical area description, internal point, and name of geographic entities.

FIPS class codes describe the general characteristics of a geographic area related to its legal or statistical 

status, governmental status, and in some cases relationship to other geographic entities. Class codes 
Geographic Terms and Concepts A-19

U.S. Census Bureau, 2010 Census Summary File 1

exist for counties; county subdivisions; subminor civil divisions; places; consolidated cities; Alaska Native 

Regional Corporations; American Indian, Alaska Native, and Native Hawaiian areas; and American Indian 

tribal subdivisions.

Functional status describes whether a geographic entity is a functioning governmental unit, has an inactive 

government, is an administrative area without a functioning government, or is a statistical area identified 

and defined solely for tabulation and presentation of statistical data. Functional status codes are:

A Active government providing primary general-purpose functions.

B Active government that is partially consolidated with another government but with separate officials 

providing primary general-purpose functions.

C Active government consolidated with another government with a single set of officials.

E Active government providing special-purpose functions.

F Fictitious entity created to fill the Census Bureau’s geographic hierarchy.

G Active government that is subordinate to another unit of government and thus, not considered a 

functioning government.

I Inactive governmental unit that has the power to provide primary special-purpose functions.

N Nonfunctioning legal entity.

S Statistical entity.

Internal point—The Census Bureau calculates an internal point (latitude and longitude coordinates) for 

each geographic entity. For many geographic entities, the internal point is at or near the geographic center 

of the entity. For some irregularly shaped entities (such as those shaped like a crescent), the calculated 

geographic center may be located outside the boundaries of the entity. In such instances, the internal 

point is identified as a point inside the entity boundaries nearest to the calculated geographic center and, 

if possible, within a land polygon. 

Legal/statistical area description (LSAD)—The LSAD describes the particular typology for each geographic 

entity; that is, whether the entity is a borough, city, county, town, or township, among others. For legal 

entities, the LSAD reflects the term that appears in legal documentation pertaining to the entity, such as a 

treaty, charter, legislation, resolution, or ordinance. For statistical entities, the LSAD is the term assigned 

by the Census Bureau or other agency defining the entity. The LSAD code is a two-character field that 

corresponds to a description of the legal or statistical type of entity and identifies whether the LSAD term 

should be capitalized and should precede or follow the name of the geographic entity. Note that the same 

LSAD code is assigned to entities at different levels of the geographic hierarchy when they share the same 

LSAD. For example, the Census Bureau assigns the same LSAD code (“21”) to boroughs in New York and 

Connecticut, although they are county subdivisions in the former and incorporated places in the latter. 

Name—Each geographic entity included in Census Bureau products has a name. For most geographic 

entities, the name is derived from the official legally recognized name, is assigned by local officials 

participating in Census Bureau statistical area programs, or is based on component entities and 

determined according to specified criteria. For legal entities, the name appearing in Census Bureau 

products may be the more commonly used name rather than the name as it appears in legal documents. 

For example, “Virginia” instead of “the Commonwealth of Virginia”; “Baltimore” instead of “City of 

Baltimore.” In some instances, the name for an entity in Census Bureau products will reflect the official 

name as well as a more commonly used name listed parenthetically; i.e., San Buenaventura (Ventura), CA, 

or Bath (Berkeley Springs), WV. For some types of geographic entities, the name reflected in Census Bureau 

products may be the geographic entity code assigned by local officials. For example, a census tract’s name 

is the actual number assigned by local officials, such as 1.01, whereas the census tract code would reflect 

a full four-digit base code and two-digit suffix (for example, for the preceding tract named 1.01, 000101).

 U.S. Census Bureau, 2010 Census Summary File 1

GEOGRAPHIC NAMES INFORMATION SYSTEM

The Geographic Names Information System (GNIS) is the federal standard for geographic nomenclature. 

The U.S. Geological Survey (USGS) developed the GNIS for the U.S. Board on Geographic Names as the 

official repository of domestic geographic names data; the official vehicle for geographic names use by 

all departments of the federal government; and the source for applying geographic names to federal 

electronic and printed products. The GNIS contains information about physical and cultural geographic 

features of all types in the United States and its territories, current and historical, but not including roads 

and highways. The database holds the federally recognized name of each feature and defines the feature 

location by state, county, USGS topographic map, and geographic coordinates. Other attributes include 

names or spellings other than the official name, feature designations, feature classification, historical and 

descriptive information, and, for some categories, the geometric boundaries.

GEOGRAPHIC NAMES INFORMATION SYSTEM IDENTIFIER

The Geographic Names Information System Identifier (GNIS ID) is a variable length, permanent, numeric 

identifier of up to ten digits in length that identifies each entity uniquely within the nation. The GNIS is the 

new American National Standards Institute (ANSI) national standard code for several entity types. Because 

each entity’s GNIS ID is permanent, it will not change if the entity changes its name or if creation of a new 

entity changes the alphabetic sort. (Federal Information Processing Series codes are assigned based on 

the alphabetic sorting of entity names within a state and occasionally require changing codes to maintain 

the alphabetic sort.) The GNIS IDs are assigned sequentially and stored in a right-justified, variable-length, 

numeric field without leading zeroes. The GNIS now contains more than 2.6 million sequential records, 

thus no GNIS ID currently exceeds seven digits. The Census Bureau portrays the GNIS ID in its data 

products as a fixed-width eight-character field with leading zeroes.

ISLAND AREAS OF THE UNITED STATES

The Island Areas of the United States are American Samoa, Guam, the Commonwealth of the Northern 

Mariana Islands (Northern Mariana Islands), and the U.S. Virgin Islands.

The Census Bureau treats the Island Areas as entities that are statistically equivalent to states for data 

presentation purposes; data for the Island Areas, however, are presented separately from data for the 

United States and Puerto Rico. Geographic definitions specific to the Island Areas are shown in the 

appropriate publications and documentation that accompany the data products for the Island Areas. 

Sometimes the Island Areas are referred to as “Island Territories” or “Insular Areas.” For the 1990 and 

previous censuses, the U.S. Census Bureau referred to the entities as “Outlying Areas.”

Separate from the Island Areas is the term “U.S. Minor Outlying Islands.” The U.S. Minor Outlying Islands 

refers to certain small islands under U.S. jurisdiction in the Caribbean and Pacific: Baker Island, Howland 

Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Islands, Navassa Island, Palmyra Atoll, and 

Wake Island. These areas usually are not part of standard data products.

MAF/TIGER DATABASE

MAF/TIGER is an acronym for the Master Address File/Topologically Integrated Geographic Encoding and 

Referencing system or database. It is a digital (computer-readable) geographic database that automates 

the mapping and related geographic activities required to support the Census Bureau’s census and 

survey programs. The Census Bureau developed the TIGER® system to automate the geographic support 

processes needed to meet the major geographic needs of the 1990 census: producing cartographic 

products to support data collection and map presentations, providing geographic structure for tabulation 

and dissemination of the collected statistical data, assigning residential and employer addresses to the 

correct geographic location and relating those locations to the geographic entities used for data tabulation, 

and so forth. During the 1990s, the Census Bureau developed an independent Master Address File (MAF) 

to support field operations and allocation of housing units for tabulations. After Census 2000, both the 
Geographic Terms and Concepts A-21

U.S. Census Bureau, 2010 Census Summary File 1

address-based MAF and geographic TIGER® databases merged to form MAF/TIGER. The content of the 

MAF/TIGER database is undergoing continuous updates and is made available to the public through a 

variety of TIGER/Line® shapefiles.

PLACE

Incorporated Places are those reported to the Census Bureau as legally in existence as of January 1, 

2010, as reported in the latest Boundary and Annexation Survey (BAS), under the laws of their respective 

states. An incorporated place is established to provide governmental functions for a concentration of 

people as opposed to a minor civil division, which generally is created to provide services or administer an 

area without regard, necessarily, to population. Places always are within a single state or equivalent entity, 

but may extend across county and county subdivision boundaries. An incorporated place usually is a city, 

town, village, or borough, but can have other legal descriptions. For Census Bureau data tabulation and 

presentation purposes, incorporated places exclude:

•	 Boroughs in Alaska (treated as statistical equivalents of counties)

•	 Towns in the New England states, New York, and Wisconsin (treated as MCDs)

•	 Boroughs in New York (treated as MCDs)

Census Designated Places (CDPs) are the statistical counterparts of incorporated places, and are 

delineated to provide data for settled concentrations of population that are identifiable by name but are 

not legally incorporated under the laws of the state in which they are located. The boundaries usually 

are defined in cooperation with local or tribal officials and generally updated prior to each decennial 

census. These boundaries, which usually coincide with visible features or the boundary of an adjacent 

incorporated place or another legal entity boundary, have no legal status, nor do these places have officials 

elected to serve traditional municipal functions. CDP boundaries may change from one decennial census 

to the next with changes in the settlement pattern; a CDP with the same name as in an earlier census does 

not necessarily have the same boundary. CDPs must be contained within a single state and may not extend 

into an incorporated place. There are no population size requirements for CDPs. 

Hawaii is the only state that has no incorporated places recognized by the Census Bureau. All places 

shown in decennial census data products for Hawaii are CDPs. By agreement with the state of Hawaii, the 

Census Bureau does not show data separately for the city of Honolulu, which is coextensive with Honolulu 

County. In Puerto Rico, which also does not have incorporated places, the Census Bureau recognizes only 

CDPs and refers to them as comunidades or zonas urbanas. Guam also has only CDPs. 

Place Codes are of two types. The five-digit Federal Information Processing Series (FIPS) place code is 

assigned based on alphabetical sequence within a state. If place names are duplicated within a state and 

they represent distinctly different areas, a separate code is assigned to each place name alphabetically 

by the primary county in which each place is located, or if both places are in the same county, they are 

assigned alphabetically by their legal descriptions (for example, “city” before “village”). Places also are 

assigned an eight-digit National Standard (ANSI) code.

Dependent and Independent Places refers to the relationship of places to the county subdivisions. 

Depending on the state, incorporated places are either dependent within, or independent of, county 

subdivisions, or there is a mixture of dependent and independent places in the state and in a county. 

Dependent places are part of the county subdivision; the county subdivision code of the place is the same 

as that of the underlying county subdivision(s) but is different from the place code. Independent places 

are not part of any minor civil division (MCD) and serve as primary county subdivisions. The independent 

place FIPS code usually is the same as that used for the MCD for the place. The only exception is if the 

place is independent of the MCDs in a state (Iowa, Louisiana, Maryland, Nebraska, North Carolina, and 

Virginia) in which the FIPS MCD codes are in the 90000 range. Then, the FIPS MCD and FIPS place codes 

will differ. CDPs always are dependent within county subdivisions and all places are dependent within 

statistical county subdivisions.

 U.S. Census Bureau, 2010 Census Summary File 1

Consolidated City (Balance) Portions refer to the areas of a consolidated city not included in another 

separately incorporated place. For example, Butte-Silver Bow, MT, is a consolidated city (former Butte city 

and Silver Bow County) that includes the separately incorporated municipality of Walkerville city. The area 

of the consolidated city that is not in Walkerville city is assigned to Butte-Silver Bow (balance). The name 

of the area of a consolidated city not specifically within a separately incorporated place always includes 

the “(balance)” identifier. Balance portions of consolidated cities are included with other places in Census 

Bureau products.

POPULATION AND HOUSING UNIT DENSITY

Population and housing unit density are computed by dividing the total population or number of housing 

units within a geographic entity by the land area of that entity measured in square miles or in square 

kilometers. Density is expressed as “population per square mile (kilometer)” or “housing units per square 

mile (kilometer).”

PUBLIC USE MICRODATA AREAS

Public Use Microdata Areas (PUMAs) are geographic areas for which the Census Bureau provides 

selected extracts of raw data from a small sample of census records that are screened to protect 

confidentiality. These extracts are referred to as public use microdata sample (PUMS) files. 

For the 2010 Census, each state, the District of Columbia, Puerto Rico, and some Island Area participants 

delineated PUMAs for use in presenting PUMS data based on a 5 percent sample of decennial census or 

American Community Survey data. These areas are required to contain at least 100,000 people. This is 

different from Census 2000 when two types of PUMAs were defined: a 5 percent PUMA as for 2010 and an 

additional super-PUMA designed to provide a 1 percent sample. The PUMAs are identified by a five-digit 

census code unique within state.

PUERTO RICO

The Census Bureau treats the Commonwealth of Puerto Rico as the statistical equivalent of a state for data 

presentation purposes.

Municipio

The primary legal divisions of Puerto Rico are termed “municipios.” For data presentation purposes, the 

Census Bureau treats a municipio as the equivalent of a county in the United States.

Barrio, Barrio-Pueblo, and Subbarrio

The Census Bureau recognizes barrios and barrios-pueblo as the primary legal divisions of municipios. 

These entities are similar to the minor civil divisions (MCDs) used for reporting data in 29 states of the 

United States. Subbarrios in 23 municipios are the primary legal subdivisions of the barrios-pueblo and 

some barrios. The Census Bureau presents the same types of statistical data for these subminor civil 

divisions (sub-MCDs) as it does for the barrios and barrios-pueblo. (There is no geographic entity in the 

United States equivalent to the subbarrio.)

Zona Urbana and Comunidad

There are no incorporated places in Puerto Rico; instead, the Census Bureau provides data for two types of 

census designated places (CDPs): zonas urbanas, representing the governmental center of each municipio, 

and comunidades, representing other settlements. There are no minimum population size requirements for 

zonas urbanas and comunidades. 

Some types of geographic entities do not apply in Puerto Rico. For instance, Puerto Rico is not in any 

census region or census division (see also “Congressional District”).

SCHOOL DISTRICTS (ELEMENTARY, SECONDARY, AND UNIFIED)

School Districts are geographic entities within which state, county, local officials, the Bureau of Indian 

Affairs, or the U.S. Department of Defense provide public educational services for the area’s residents. The 

Census Bureau obtains the boundaries, names, local education agency codes, and school district levels 

for school districts from state and local school officials for the primary purpose of providing the U.S. 

Department of Education with estimates of the number of children “at risk” within each school district, 

county, and state. This information serves as the basis for the Department of Education to determine the 

annual allocation of Title I funding to states and school districts.

The Census Bureau tabulates data for three types of school districts: elementary, secondary, and unified. 

Each school district is assigned a five-digit code that is unique within state. School district codes are 

the local education agency number assigned by the Department of Education and are not necessarily in 

alphabetical order by school district name.

The elementary school districts provide education to the lower grade/age levels and the secondary school 

districts provide education to the upper grade/age levels. Unified school districts provide education to 

children of all school ages in their service areas. In general, where there is a unified school district, no 

elementary or secondary school district exists; and where there is an elementary school district, the 

secondary school district may or may not exist.

The Census Bureau’s representation of school districts in various data products is based both on the grade 

range that a school district operates and also the grade range for which the school district is financially 

responsible. For example, a school district is defined as an elementary school district if its operational 

grade range is less than the full kindergarten through 12 or prekindergarten through 12 grade range (for 

example, K–6 or pre-K–8). These elementary school districts do not provide direct educational services 

for grades 7–12, 9–12, or similar ranges. Some elementary school districts are financially responsible 

for the education of all school-aged children within their service areas and rely on other school districts 

to provide service for those grade ranges that are not operated by these elementary school districts. 

In these situations, in order to allocate all school-aged children to these school districts, the secondary 

school district code field is blank. For elementary school districts where the operational grade range and 

financially responsible grade range are the same, the secondary school district code field will contain a 

secondary school district code. There are no situations where an elementary school district does not exist 

and a secondary school district exists in Census Bureau records.

STATE OR STATISTICALLY EQUIVALENT ENTITY

States and Equivalent Entities are the primary governmental divisions of the United States. In addition 

to the 50 states, the Census Bureau treats the District of Columbia, Puerto Rico, American Samoa, the 

Commonwealth of the Northern Mariana Islands, Guam, and the U.S. Virgin Islands as the statistical 

equivalents of states for the purpose of data presentation. 

STATE LEGISLATIVE DISTRICTS (UPPER AND LOWER CHAMBERS)

State Legislative Districts (SLDs) are the areas from which members are elected to state legislatures. 

The Census Bureau first reported data for SLDs as part of the 2000 Public Law (P.L.) 94-171 Redistricting 

Data File.

Current SLDs (2010 Election Cycle)—States participating in Phase 1 of the 2010 Census Redistricting 

Data Program voluntarily provided the Census Bureau with the 2006 election cycle boundaries, codes, 

and, in some cases, names for their SLDs. All 50 states, plus the District of Columbia and Puerto Rico, 

participated in Phase 1, State Legislative District Project (SLDP) of the 2010 Census Redistricting Data 

Program. States subsequently provided legal changes to those plans through the Redistricting Data Office 

and/or corrections as part of Phase 2 of the 2010 Census Redistricting Data Program, as needed.
A-24 Geographic Terms and Concepts

 U.S. Census Bureau, 2010 Census Summary File 1

The SLDs embody the upper (senate—SLDU) and lower (house—SLDL) chambers of the state legislature. 

Nebraska has a unicameral legislature and the District of Columbia has a single council, both of which the 

Census Bureau treats as upper-chamber legislative areas for the purpose of data presentation. A unique 

three-character census code, identified by state participants, is assigned to each SLD within a state. In 

Connecticut, Hawaii, Illinois, Louisiana, Maine, Massachusetts, New Jersey, Ohio, and Puerto Rico, state 

officials did not define the SLDs to cover all of the state or state equivalent area (usually bodies of water). 

In these areas with no SLDs defined, the code “ZZZ” has been assigned, which is treated within state as a 

single SLD for purposes of data presentation. Maryland also has areas with no SLDs defined; in Maryland, 

these areas are coded with an initial “Z” by county or equivalent and treated as a unique SLD by county 

or equivalent. In Nebraska and the District of Columbia, the Census Bureau assigned the code 999 to 

represent a single SLDL where legally none exist.

SLD Names—The Census Bureau first reported names for SLDs as part of Phase 1 of the 2010 Census 

Redistricting Data Program. The SLD names with their translated legal/statistical area description are 

associated only with the current SLDs. Not all states provided names for their SLDs, therefore the code (or 

number) also serves as the name.

TRIBAL BLOCK GROUP

The 2010 tribal block group concept and criteria are completely different from those used in 2000. For 

the Census 2000, tribal block groups were the standard state-county-census tract-block group areas 

retabulated under an American Indian area hierarchy; that is, American Indian area-tribal census tracttribal block group. Tribal block groups only were applicable to legal federally recognized American Indian 

reservation and off-reservation trust land areas. Tribal block groups were defined to provide statistically 

significant sample data for small areas within American Indian areas, particularly those American Indian 

areas that crossed state or county boundaries where these boundaries were not meaningful for statistical 

purposes. The 2000 tribal block groups used the block group numbers and comprised all blocks beginning 

with a single number.

The 2010 tribal block groups are defined independently of the standard county-based block group 

delineation. For federally recognized American Indian tribes with reservations or off-reservation trust land 

and a population less than 1,200, a single tribal block group is defined. Tribal participants in qualifying 

areas with a population greater than 1,200 could define additional block groups within their reservation 

and/or off-reservation trust land without regard to the standard block group configuration.

Tribal block groups will contain blocks beginning with the same number as the standard county-based 

block group and could contain seemingly duplicate block numbers. To better identify and differentiate 

tribal block groups from county-based block groups, tribal block groups use the letter range A through K 

(except “I,” which could be confused with a number “1”) to identify and code the tribal block group. Tribal 

block groups nest within tribal census tract.

TRIBAL CENSUS TRACT

The 2010 tribal census tract concept and criteria are completely different from those used in 2000. Tribal 

census tracts (also known as tribal tracts) in 2000 were the standard state-county-census tract areas 

retabulated under an American Indian area hierarchy; that is, American Indian area-tribal census tract. 

Federally recognized tribes with a reservation or off-reservation trust land delineated tribal census tracts 

working with local census tract participants to produce a single census tract plan. Tribal census tracts were 

designed to be permanent statistical divisions of American Indian areas for the presentation of comparable 

data between censuses, particularly for those American Indian areas that crossed state or county 

boundaries where these boundaries were not meaningful for statistical purposes.

For 2010, tribal census tracts are defined independently of the standard county-based tract delineation. 

For federally recognized American Indian tribes with reservations or off-reservation trust land and a 
Geographic Terms and Concepts A-25

U.S. Census Bureau, 2010 Census Summary File 1

population less than 2,400, a single tribal census tract is defined. Qualifying areas with a population 

greater than 2,400 could define additional tribal census tracts within their area.

In 2000, the tract number range of 9400 through 9499 was reserved for tribal census tracts and was 

required for those tribal census tracts that crossed state or county boundaries. Not all tribal census tracts 

in 2000, however, used this range. For 2010, tribal census tract codes will be six characters long with a 

leading “T” alphabetic character followed by five numeric codes having an implied decimal between the 

fourth and fifth character; for example, T01000, which translates as tribal census tract 10. Tribal block 

groups will nest within tribal census tract. Since individual blocks are defined within the standard statecounty-census tract hierarchy, a tribal census tract can contain seemingly duplicate block numbers, thus 

tribal census tracts cannot be used to uniquely identify census blocks.

UNITED STATES

The United States consists of the 50 states and the District of Columbia.

URBAN AND RURAL

For the 2010 Census, the Census Bureau classified as urban all territory, population, and housing units 

located within urbanized areas (UAs) and urban clusters (UCs), both defined using the same criteria. The 

Census Bureau delineates UA and UC boundaries that represent densely developed territory, encompassing 

residential, commercial, and other nonresidential urban land uses. In general, this territory consists of 

areas of high population density and urban land use resulting in a representation of the “urban footprint.” 

Rural consists of all territory, population, and housing units located outside UAs and UCs. 

For the 2010 Census, the urban and rural classification was applied to the 50 states, the District of 

Columbia, Puerto Rico, American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and 

the U.S. Virgin Islands.

Urbanized Areas (UAs)—An urbanized area consists of densely developed territory that contains 50,000 

or more people. The Census Bureau delineates UAs to provide a better separation of urban and rural 

territory, population, and housing in the vicinity of large places. 

Urban Clusters (UCs)—An urban cluster consists of densely developed territory that has at least 2,500 

people but fewer than 50,000 people. The Census Bureau first introduced the UC concept for Census 2000 

to provide a more consistent and accurate measure of urban population, housing, and territory throughout 

the United States, Puerto Rico, and the Island Areas.

Urban Area Titles and Codes—The title of each UA and UC may contain up to three incorporated place 

or census designated place (CDP) names and will include the two-letter U.S. Postal Service abbreviation 

for each state or statistically equivalent entity into which the UA or UC extends. However, if the UA or UC 

does not contain an incorporated place or CDP, the urban area title will include the single name of a minor 

civil division or populated place recognized by the U.S. Geological Survey’s Geographic Names Information 

System.

Each UC and UA is assigned a five-digit numeric census code based on a national alphabetical sequence of 

all urban area names. A separate flag is included in data tabulation files to differentiate between UAs and 

UCs. In printed reports, this differentiation is included in the name.

Central Place—The 2010 Census urban areas will no longer include one or more designated central 

places. In preceding censuses, the central place included all incorporated or census designated places 

included in the urban area title, plus additional incorporated areas that met a population size criterion. The 

concept of central place for urban areas no longer is being applied.

Relationship to Other Geographic Entities—Geographic entities, such as metropolitan areas, counties, 

minor civil divisions, places, and census tracts, often contain both urban and rural territory, population, 

and housing units.
A-26 Geographic Terms and Concepts

 U.S. Census Bureau, 2010 Census Summary File 1

URBAN GROWTH AREAS

Urban Growth Areas (UGAs) are legally defined entities in Oregon and Washington that the Census 

Bureau includes in the MAF/TIGER database in agreement with the states. UGAs, which are defined around 

incorporated places, are used to regulate urban growth. UGA boundaries, which need not follow visible 

features, are delineated cooperatively by state and local officials and then confirmed in state law. UGAs are 

a pilot project first defined only in Oregon for Census 2000. Each UGA is identified by a five-digit numeric 

census code, usually the same as the five-digit Federal Information Processing Series (FIPS) code associated 

with the incorporated place for which the UGA is named.

VOTING DISTRICTS

Voting Districts (VTDs) refer to the generic name for geographic entities, such as precincts, wards, 

and election districts, established by state governments for the purpose of conducting elections. States 

voluntarily participating in Phase 2 of the 2010 Census Redistricting Data Program provided the Census 

Bureau with boundaries, codes, and names for their VTDs. Each VTD is identified by a one-to-six-character 

alphanumeric census code that is unique within county. The code “ZZZZZZ” identifies a portion of counties 

(usually bodies of water) for which no VTDs were identified. For the 2010 Census, only Rhode Island did 

not participate in Phase 2 (the Voting District/Block Boundary Suggestion Project) of the 2010 Census 

Redistricting Data Program. Kentucky chose not to provide VTDs as part of their participation in Phase 2, 

and the states of Montana and Oregon provided VTDs for some counties. Therefore, for 2010 Census data 

products, no VTDs exist in select counties in Montana and Oregon or for the states of Rhode Island and 

Kentucky in their entirety. Participating states often submitted VTDs conforming to the feature network 

in the MAF/TIGER database rather than the complete legal boundary of the VTD. If requested by the 

participating state, the Census Bureau identified the VTDs that represent an actual voting district with an “A” 

in the voting district indicator field. Where a participating state indicated that the VTD has been modified to 

follow existing features, the VTD is a pseudo-VTD, and the voting district indicator contains “P.” 

ZIP CODE TABULATION AREAS

ZIP Code Tabulation Areas (ZCTAs) are approximate area representations of U.S. Postal Service (USPS) 

five-digit ZIP Code service areas that the Census Bureau creates using whole blocks to present statistical 

data from censuses and surveys. The Census Bureau defines ZCTAs by allocating each block that contains 

addresses to a single ZCTA, usually to the ZCTA that reflects the most frequently occurring ZIP Code 

for the addresses within that tabulation block. Blocks that do not contain addresses but are completely 

surrounded by a single ZCTA (enclaves) are assigned to the surrounding ZCTA; those surrounded by 

multiple ZCTAs will be added to a single ZCTA based on limited buffering performed between multiple 

ZCTAs. The Census Bureau identifies five-digit ZCTAs using a five-character numeric code that represents 

the most frequently occurring USPS ZIP Code within that ZCTA, and this code may contain leading zeros.

There are significant changes to the 2010 ZCTA delineation from that used in 2000. Coverage was 

extended to include the Island Areas for 2010 so that the United States, Puerto Rico, and the Island Areas 

have ZCTAs. Unlike 2000, when areas that could not be assigned to a ZCTA were given a generic code 

ending in “XX” (land area) or “HH” (water area), for 2010 there is no universal coverage by ZCTAs, and 

only legitimate five-digit areas are defined. The 2010 ZCTAs will better represent the actual Zip Code 

service areas because the Census Bureau initiated a process before creation of 2010 blocks to add block 

boundaries that split polygons with large numbers of addresses using different Zip Codes.

Data users should not use ZCTAs to identify the official USPS ZIP Code for mail delivery. The USPS makes 

periodic changes to ZIP Codes to support more efficient mail delivery. The ZCTAs process used primarily 

residential addresses and was biased towards Zip Codes used for city-style mail delivery, thus there may 

be Zip Codes that are primarily nonresidential or boxes only that may not have a corresponding ZCTA.

INTRODUCTION

The 2010 Census data products provide, except where specifically noted, counts of the resident 

population of the United States. The U.S. resident population includes everyone whose usual place of 

residence was in the 50 states and the District of Columbia at the time of the 2010 Census.

In the design of summary file tables, the Census Bureau strives for consistency in terminology and cell 

label structure to facilitate processing, review, and usability. Data users see the same patterns repeated in 

various cross-tabulated tables. Unfortunately, at times, the use of a pattern creates illogical results, such as 

the display of data for the population 65 years and over in juvenile correctional facilities.

POPULATION CHARACTERISTICS

Age

The data on age were derived from answers to a two-part question (i.e., age and date of birth). The age 

classification for a person in census tabulations is the age of the person in completed years as of 

April 1, 2010, the census reference date. Both age and date of birth responses are used in combination to 
B-2 Definitions of Subject Characteristics

U.S. Census Bureau, 2010 Census Summary File 1

determine the most accurate age for the person as of the census reference date. Inconsistently reported 

and missing values are assigned or allocated based on the values of other variables for that person, from 

other people in the household or from people in other households (i.e., hot-deck imputation). 

Age data are tabulated in age groupings and single years of age. Data on age also are used to classify 

other characteristics in census tabulations. 

Median Age—This measure divides the age distribution into two equal parts: one-half of the cases falling 

below the median value and one-half above the value. Median age is computed on the basis of a singleyear-of-age distribution using a linear interpolation method. 

Limitation of the data—There is some tendency for respondents to provide their age as of the date they 

completed the census questionnaire or interview, not their age as of the census reference date. The twopart question and editing procedures have attempted to minimize the effect of this reporting problem on 

tabulations. Additionally, the current census age question displays the census reference date prominently, 

and interviewer training emphasizes the importance of collecting age as of the reference date.

Respondents sometimes round a person’s age up if they were close to having a birthday. For most single 

years of age, the misstatements are largely offsetting. The problem is most pronounced at age 0. Also, 

there may have been more rounding up to age 1 to avoid reporting age as 0 years. (Age in completed 

months was not collected for infants under age 1.) Editing procedures correct this problem. 

There is some respondent resistance to reporting the ages of babies in completed years (i.e., 0 years old 

when the baby is under 1 year old). Instead, babies’ ages are sometimes reported in months. The twopart question along with enhanced editing and data capture procedures correct much of this problem 

before the age data are finalized in tabulations. Additionally, the current census age question includes an 

instruction for babies’ ages to be answered as “0” years old when they are under 1 year old.

Age heaping is a common age misreporting error. Age heaping is the tendency for people to overreport 

ages (or years of birth) that end in certain digits (commonly digits “0” or “5”) and underreport ages or years 

of birth ending in other digits. The two-part question helps minimize the effect of age heaping on the final 

tabulations.

Age data for centenarians have a history of data quality challenges. The counts in the 1970 and 1980 

Censuses for people 100 years and over were substantially overstated. Editing and data collection 

methods have been enhanced in order to meet the data quality challenges for this population.

It also has been documented that the population aged 69 in the 1970 Census and the population aged 

79 in the 1980 Census were overstated. The population aged 89 in 1990 and the population aged 99 in 

2000 did not have an overstated count. (For more information on the design of the age question, see the 

“Comparability” section below.) 

Comparability—Age data have been collected in every census. However, there have been some 

differences in the way they have been collected and processed over time. In the 2010 Census (as in Census 

2000), each individual provided both an age and an exact date of birth. The 1990 Census collected age 

and year of birth. Prior censuses had collected month and quarter of birth in addition to age and year of 

birth. The 1990 Census change was made so that coded information could be obtained for both age and 

year of birth.

In each census since 1940, the age of a person was assigned when it was not reported. In censuses before 

1940, with the exception of 1880, people of unknown age were shown as a separate category. Since 

1960, assignment of unknown age has been performed by a general procedure described as “imputation.” 

The specific procedures for imputing age have been different in each census. (For more information on 

imputation, see “2010 Census: Operational Overview and Accuracy of the Data.”)

Hispanic or Latino Origin

The data on the Hispanic or Latino population were derived from answers to a question that was asked 

of all people. The terms “Hispanic,” “Latino,” and “Spanish” are used interchangeably. Some respondents 

identify with all three terms, while others may identify with only one of these three specific terms. People 

who identify with the terms “Hispanic,” “Latino,” or “Spanish” are those who classify themselves in one of 

the specific Hispanic, Latino, or Spanish categories listed on the questionnaire (“Mexican,” “Puerto Rican,” 

or “Cuban”) as well as those who indicate that they are “another Hispanic, Latino, or Spanish origin.” People 

who do not identify with one of the specific origins listed on the questionnaire but indicate that they are 

“another Hispanic, Latino, or Spanish origin” are those whose origins are from Spain, the Spanish-speaking 

countries of Central or South America, or the Dominican Republic. Up to two write-in responses to the 

“another Hispanic, Latino, or Spanish origin” category are coded. 

Origin can be viewed as the heritage, nationality group, lineage, or country of birth of the person or the 

person’s parents or ancestors before their arrival in the United States. People who identify their origin as 

Hispanic, Latino, or Spanish may be any race. 

Some tabulations are shown by the origin of the householder. In all cases where the origin of households, 

families, or occupied housing units is classified as Hispanic, Latino, or Spanish, the origin of the 

householder is used. (See the discussion of householder under “Household Type and Relationship.”) 

If an individual did not provide a Hispanic origin response, his or her origin was allocated using specific 

rules of precedence of household relationship. For example, if origin was missing for a natural-born child 

in the household, then either the origin of the householder, another natural-born child, or spouse of the 

householder was allocated. 

If Hispanic origin was not reported for anyone in the household and origin could not be obtained from a 

response to the race question, then their origin was assigned based on their prior census record (either 

from Census 2000 or the American Community Survey), if available. If not, then the Hispanic origin of a 

householder in a previously processed household with the same race was allocated. (For more information 

on allocation, see “2010 Census: Operational Overview and Accuracy of the Data.”) As in Census 2000, 

surnames (Spanish and non-Spanish) were used to assist in allocating an origin or race. 

Comparability—There are four changes to the Hispanic origin question for the 2010 Census. First, the 

wording of the question differs from that in 2000. In 2000, the question asked if the person was “Spanish/

Hispanic/Latino.” In 2010, the question asks if the person is “of Hispanic, Latino, or Spanish origin.” 

Second, in 2000, the question provided an instruction, “Mark ý the ‘No’ box if not Spanish/Hispanic/

Latino.” The 2010 Census question provided no specific instruction for non-Hispanics. Third, in 2010, 

the “Yes, another Hispanic, Latino, or Spanish origin” category provided examples of six Hispanic origin 

groups (Argentinean, Colombian, Dominican, Nicaraguan, Salvadoran, Spaniard, and so on) and instructed 

respondents to “print origin.” In 2000, no Hispanic origin examples were given. Finally, the fourth 

change was the addition of a new instruction in the 2010 Census that was not used in Census 2000. The 

instruction is stated as follows: “NOTE: Please answer BOTH Question 8 about Hispanic origin and Question 

9 about race. For this census, Hispanic origins are not races.”
B-4 Definitions of Subject Characteristics

U.S. Census Bureau, 2010 Census Summary File 1

There were two changes to the Hispanic origin question for Census 2000. First, the sequence of the race 

and Hispanic origin questions for Census 2000 differs from that in 1990; in 1990, the race question 

preceded the Hispanic origin question. Testing prior to Census 2000 indicated that response to the 

Hispanic origin question could be improved by placing it before the race question without affecting the 

response to the race question. Second, there was an instruction preceding the Hispanic origin question 

indicating that respondents should answer both the Hispanic origin and the race questions. This 

instruction was added to give emphasis to the distinct concepts of the Hispanic origin and race questions, 

and emphasized the need for both pieces of information. 

Furthermore, there was a change in the processing of the Hispanic origin and race responses. In the 1990 

census, respondents provided Hispanic origin responses in the race question and race responses in the 

Hispanic origin question. In 1990, the Hispanic origin question and the race question had separate edits; 

therefore, although information may have been present on the questionnaire, it was not fully utilized due 

to the discrete nature of the edits. However, for Census 2000, there was a joint race and Hispanic origin 

edit that utilized Hispanic origin and race information regardless of the location. 

Household Type and Relationship

Household

A household includes all the people who occupy a housing unit. (People not living in households are 

classified as living in group quarters.) A housing unit is a house, an apartment, a mobile home, a group 

of rooms, or a single room that is occupied (or if vacant, is intended for occupancy) as separate living 

quarters. Separate living quarters are those in which the occupants live separately from any other people 

in the building and which have direct access from the outside of the building or through a common hall. 

The occupants may be a single family, one person living alone, two or more families living together, or 

any other group of related or unrelated people who share living arrangements. In the 2010 Census data 

products, the count of households or householders equals the count of occupied housing units.

Average Household Size—Average household size is a measure obtained by dividing the number of 

people in households by the number of households. In cases where people in households are crossclassified by race or Hispanic origin, people in the household are classified by the race or Hispanic origin 

of the householder rather than the race or Hispanic origin of each individual. Average household size is 

rounded to the nearest hundredth. 

Relationship to Householder

Householder—The data on relationship to householder were derived from answers to Question 2, which 

was asked of all people in housing units. One person in each household is designated as the householder. 

In most cases, this is the person, or one of the people, in whose name the home is owned, being bought, 

or rented and who is listed on line one of the questionnaire. If there is no such person in the household, 

any adult household member 15 years old and over could be designated as the householder. 

Households are classified by type according to the sex of the householder and the presence of relatives. 

Two types of householders are distinguished: a family householder and a nonfamily householder. A family 

householder is a householder living with one or more individuals related to him or her by birth, marriage, 

or adoption. The householder and all people in the household related to him or her are family members. A 

nonfamily householder is a householder living alone or with nonrelatives only.

Spouse—The “spouse” category includes a person identified as the husband or wife of the householder 

and who is of the opposite sex. For most of the tables, unless otherwise specified, it does not include 

same-sex spouses even if a marriage was performed in a state issuing marriage certificates for same-sex 

couples. 
Definitions of Subject Characteristics B-5

U.S. Census Bureau, 2010 Census Summary File 1

Child—The “child” category includes a son or daughter by birth, a stepchild, or adopted child of the 

householder, regardless of the child’s age or marital status. The category excludes sons-in-law, daughtersin-law, and foster children.

Biological Son or Daughter—The son or daughter of the householder by birth.

Adopted Son or Daughter—The son or daughter of the householder by legal adoption. If a stepson, 

stepdaughter, or foster child has been legally adopted by the householder, the child is then classified as 

an adopted child.

Stepson or Stepdaughter—The son or daughter of the householder through marriage but not by 

birth, excluding sons-in-law and daughters-in-law. If a stepson or stepdaughter of the householder has 

been legally adopted by the householder, the child is then classified as an adopted child. 

Own Children—A child under 18 years who is a son or daughter by birth, a stepchild, or an adopted child 

of the householder is included in the “own children” category. 

Related Children—Any child under 18 years old who is related to the householder by birth, marriage, or 

adoption is included in the “related children” category. Children, by definition, exclude persons under 18 

years who maintain households or are spouses or unmarried partners of householders. 

Other Relatives—In tabulations, the category “other relatives” includes any household member related 

to the householder by birth, marriage, or adoption but not included specifically in another relationship 

category. In certain detailed tabulations, the following categories may be shown:

Grandchild—The grandson or granddaughter of the householder. 

Brother/Sister—The brother or sister of the householder, including stepbrothers, stepsisters, and 

brothers and sisters by adoption. Brothers-in-law and sisters-in-law are included in the “Other Relative” 

category on the questionnaire.

Parent—The father or mother of the householder, including a stepparent or adoptive parent. Fathers-inlaw and mothers-in-law are included in the “Parent-in-law” category on the questionnaire. 

Parent-in-Law—The mother-in-law or father-in-law of the householder.

Son-in-law or Daughter-in-Law—The spouse of the child of the householder. 

Other Relatives—Anyone not listed in a reported category above who is related to the householder by 

birth, marriage, or adoption (brother-in-law, grandparent, nephew, aunt, cousin, and so forth). 

Nonrelatives—This category includes any household member not related to the householder by birth, 

marriage, or adoption. The following categories may be presented in more detailed tabulations:

Roomer or Boarder—A roomer or boarder is a person who lives in a room in the household of the 

householder. Some sort of cash or noncash payment (e.g., chores) is usually made for their living 

accommodations.

Housemate or Roommate—A housemate or roommate is a person aged 15 years and over who is not 

related to the householder and who shares living quarters primarily in order to share expenses.

Unmarried Partner—An unmarried partner is a person aged 15 years and over who is not related 

to the householder, who shares living quarters, and who has a close personal relationship with the 

householder. Responses of “same-sex spouse” are edited into this category.

Other Nonrelatives—Anyone who is not related by birth, marriage, or adoption to the householder 

and who is not described by the categories given above. Unrelated foster children or unrelated foster 

adults are included in this category, “Other Nonrelatives.” A foster child who has been adopted by the 

householder is classified as an adopted child.
B-6 Definitions of Subject Characteristics

U.S. Census Bureau, 2010 Census Summary File 1

When relationship is not reported for an individual, it is allocated according to the responses for age and 

sex for that person while maintaining consistency with responses for other individuals in the household. 

(For more information on allocation, see “2010 Census: Operational Overview and Accuracy of the Data.”) 

Families

Family Type—A family consists of a householder and one or more other people living in the same 

household who are related to the householder by birth, marriage, or adoption. All people in a household 

who are related to the householder are regarded as members of his or her family. A family household 

may contain people not related to the householder, but those people are not included as part of the 

householder’s family in tabulations. Thus, the number of family households is equal to the number of 

families, but family households may include more members than do families. A household can contain 

only one family for purposes of tabulations. Not all households contain families since a household may 

be comprised of a group of unrelated people or of one person living alone—these are called “nonfamily 

households.” Same-sex unmarried partner households are included in the “family households” category 

only if there is at least one additional person related to the householder by birth or adoption.

Families are classified by type as either a “husband-wife family” or “other family” according to the sex of 

the householder and the presence of relatives. The data on family type are based on answers to questions 

on sex and relationship.

Husband-Wife Family—A family in which the householder and his or her spouse of the opposite sex 

are enumerated as members of the same household. 

Other Family:

•	 Male householder, no wife present—A family with a male householder and no wife of householder 

present.

•	 Female householder, no husband present—A family with a female householder and no husband of 

householder present. 

Average Family Size—Average family size is a measure obtained by dividing the number of people in 

families by the total number of families (or family householders). In cases where the measures “people in 

family” or “people per family” are cross-tabulated by race or Hispanic origin, the race or Hispanic origin 

refers to the householder rather than the race or Hispanic origin of each individual. Nonrelatives of the 

householder living in family households are not counted as part of the family. They are included in the 

count of average household size. Average family size is rounded to the nearest hundredth. 

Multigenerational Household

A multigenerational household is one that contains three or more parent-child generations; for example, 

the householder, child of householder (either biological, stepchild, or adopted child), and grandchildren 

of householder. A householder with a parent or parent-in-law of the householder and a child of the 

householder may also be a multigenerational household.

Unmarried-Partner Household

An unmarried-partner household is a household other than a “husband-wife household” that includes 

a householder and an unmarried partner. An “unmarried partner” can be of the same sex or of the 

opposite sex as the householder. An “unmarried partner” in an “unmarried-partner household” is an adult 

who is unrelated to the householder but shares living quarters and has a close personal relationship 

with the householder. An unmarried-partner household also may be a family household or a nonfamily 

household, depending on the presence or absence of another person in the household who is related 

to the householder. There may be only one unmarried partner per household, and an unmarried partner 

may not be included in a husband-wife household, as the householder cannot have both a spouse and an 

unmarried partner. Same-sex married-couple households are edited into this category. 
Definitions of Subject Characteristics B-7

U.S. Census Bureau, 2010 Census Summary File 1

Comparability—The 2000 relationship category “Natural-born son/daughter” has been replaced by 

“Biological son or daughter” for 2010. The category “Foster child” was dropped due to space limitations 

on the 2010 questionnaire. Foster children in 2010 are included in the category “Other nonrelatives.” 

They cannot be tabulated separately. The term “married-couple” family in tabulations has been replaced 

by “husband-wife” family. In all standard 2010 tabulations, the term “spouse” refers to only a person who 

is married to and living with the householder and is of the opposite sex. Data for unmarried partners are 

comparable to data presented in 2000. Data on same-sex couple households will be presented for the first 

time in a special product. 

Institutionalized Population 

See “Group Quarters.”

Noninstitutionalized Population 

See “Group Quarters.”

Race

The data on race were derived from answers to the question on race that was asked of all people. The U.S. 

Census Bureau collects race data in accordance with guidelines provided by the U.S. Office of Management 

and Budget (OMB), and these data are based on self-identification. The racial categories included in the 

census questionnaire generally reflect a social definition of race recognized in this country and not an 

attempt to define race biologically, anthropologically, or genetically. In addition, it is recognized that the 

categories of the race item include racial and national origin or sociocultural groups. People may choose 

to report more than one race to indicate their racial mixture, such as “American Indian” and “White.” People 

who identify their origin as Hispanic, Latino, or Spanish may be any race.

The racial classifications used by the Census Bureau adhere to the October 30, 1997, Federal Register

notice entitled, “Revisions to the Standards for the Classification of Federal Data on Race and Ethnicity” 

issued by OMB. These standards govern the categories used to collect and present federal data on race 

and ethnicity. OMB requires five minimum categories (White, Black or African American, American Indian 

or Alaska Native, Asian, and Native Hawaiian or Other Pacific Islander) for race. The race categories are 

described below with a sixth category, “Some Other Race,” added with OMB approval. In addition to the 

five race groups, OMB also states that respondents should be offered the option of selecting one or more 

races. 

If an individual did not provide a race response, the race or races of the householder or other household 

members were imputed using specific rules of precedence of household relationship. For example, if race 

was missing for a natural-born child in the household, then either the race or races of the householder, 

another natural-born child, or spouse of the householder were allocated. 

If race was not reported for anyone in the household, then their race was imputed based on their prior 

census record (either from Census 2000 or the American Community Survey), if available. If not, then the 

race or races of a householder in a previously processed household were allocated. 

Definitions from OMB guide the Census Bureau in classifying written responses to the race question:

White—A person having origins in any of the original peoples of Europe, the Middle East, or North 

Africa. It includes people who indicate their race as “White” or report entries such as Irish, German, 

Italian, Lebanese, Arab, Moroccan, or Caucasian.

Black or African American—A person having origins in any of the Black racial groups of Africa. It 

includes people who indicate their race as “Black, African Am., or Negro” or report entries such as 

African American, Kenyan, Nigerian, or Haitian. 
B-8 Definitions of Subject Characteristics

U.S. Census Bureau, 2010 Census Summary File 1

American Indian or Alaska Native—A person having origins in any of the original peoples of North 

and South America (including Central America) and who maintains tribal affiliation or community 

attachment. This category includes people who indicate their race as “American Indian or Alaska Native” 

or report entries such as Navajo, Blackfeet, Inupiat, Yup’ik, or Central American Indian groups or South 

American Indian groups.

Respondents who identified themselves as “American Indian or Alaska Native” were asked to report 

their enrolled or principal tribe. Therefore, tribal data in tabulations reflect the written entries reported 

on the questionnaires. Some of the entries (for example, Metlakatla Indian Community and Umatilla) 

represent reservations or a confederation of tribes on a reservation. The information on tribe is based 

on self-identification and, therefore, does not reflect any designation of federally or state-recognized 

tribe. The information for the 2010 Census was derived from the American Indian and Alaska Native 

Tribal Classification List for Census 2000 and updated from 2002 to 2009 based on the annual Federal

Register notice entitled “Indian Entities Recognized and Eligible to Receive Services From the United 

States Bureau of Indian Affairs,” Department of the Interior, Bureau of Indian Affairs, issued by OMB, and 

through consultation with American Indian and Alaska Native communities and leaders.

The American Indian categories shown in Summary Files 1 and 2 represent tribal groupings, which refer 

to the combining of individual American Indian tribes, such as Fort Sill Apache, Mescalero Apache, and 

San Carlos Apache, into the general Apache tribal grouping. 

The Alaska Native categories shown in Summary Files 1 and 2 represent tribal groupings, which refer to 

the combining of individual Alaska Native tribes, such as King Salmon Tribe, Native Village of Kanatak, 

and Sun’aq Tribe of Kodiak, into the general Aleut tribal grouping.

Asian—A person having origins in any of the original peoples of the Far East, Southeast Asia, or the 

Indian subcontinent, including, for example, Cambodia, China, India, Japan, Korea, Malaysia, Pakistan, 

the Philippine Islands, Thailand, and Vietnam. It includes people who indicate their race as “Asian 

Indian,” “Chinese,” “Filipino,” “Korean,” “Japanese,” “Vietnamese,” and “Other Asian” or provide other 

detailed Asian responses. 

Asian Indian—Includes people who indicate their race as “Asian Indian” or report entries such as India 

or East Indian.

Bangladeshi—Includes people who provide a response such as Bangladeshi or Bangladesh.

Bhutanese—Includes people who provide a response such as Bhutanese or Bhutan.

Burmese—Includes people who provide a response such as Burmese or Burma.

Cambodian—Includes people who provide a response such as Cambodian or Cambodia.

Chinese—Includes people who indicate their race as “Chinese” or report entries such as China or 

Chinese American. In some census tabulations, written entries of Taiwanese are included with 

Chinese, while in others they are shown separately.

Filipino—Includes people who indicate their race as “Filipino” or report entries such as Philippines or 

Filipino American.

Hmong—Includes people who provide a response such as Hmong or Mong.

Indonesian—Includes people who provide a response such as Indonesian or Indonesia.

Japanese—Includes people who indicate their race as “Japanese” or report entries such as Japan or 

Japanese American.

Korean—Includes people who indicate their race as “Korean” or report entries such as Korea or 

Korean American.

on the census questionnaire and did not write in a specific group or wrote in a generic term such as 

“Asian” or “Asiatic.” 

Native Hawaiian or Other Pacific Islander—A person having origins in any of the original peoples 

of Hawaii, Guam, Samoa, or other Pacific Islands. It includes people who indicate their race as “Native 

Hawaiian,” “Guamanian or Chamorro,” “Samoan,” and “Other Pacific Islander” or provide other detailed 

Pacific Islander responses.

Native Hawaiian—Includes people who indicate their race as “Native Hawaiian” or report entries such 

as Part Hawaiian or Hawaiian. 

Samoan—Includes people who indicate their race as “Samoan” or report entries such as American 

Samoan or Western Samoan. 

Tongan—Includes people who provide a response such as Tongan or Tonga.

Other Polynesian—Includes people who provide a response of another Polynesian group, such as 

Tahitian, Tokelauan, or wrote in a generic term such as “Polynesian.” 

Guamanian or Chamorro—Includes people who indicate their race as “Guamanian or Chamorro” or 

report entries such as Chamorro or Guam.

Marshallese—Includes people who provide a response such as Marshallese or Marshall Islands. 

Other Micronesian—Includes people who provide a response of another Micronesian group, such as 

Carolinian, Chuukese, I-Kiribati, Kosraean, Mariana Islander, Palauan, Pohnpeian, Saipanese, Yapese, 

or wrote in a generic term such as “Micronesian.” 

Fijian—Includes people who provide a response such as Fijian or Fiji.

Other Melanesian—Includes people who provide a response of another Melanesian group, such as 

Guinean, Hebrides Islander, Solomon Islander, or wrote in a generic term such as “Melanesian.” 

Other Pacific Islander, not specified—Includes respondents who checked the Other Pacific Islander 

response category on the census questionnaire and did not write in a specific group or wrote in a 

generic term such as “Pacific Islander.” 

Some Other Race—Includes all other responses not included in the “White,” “Black or African American,” 

“American Indian or Alaska Native,” “Asian,” and “Native Hawaiian or Other Pacific Islander” race categories 

described above. Respondents reporting entries such as multiracial, mixed, interracial, or a Hispanic,

Latino, or Spanish group (for example, Mexican, Puerto Rican, Cuban, or Spanish) in response to the race 

question are included in this category.

Two or More Races—People may choose to provide two or more races either by checking two or more 

race response check boxes, by providing multiple responses, or by some combination of check boxes 

and other responses. The race response categories shown on the questionnaire are collapsed into the 

five minimum race groups identified by OMB and the Census Bureau’s “Some Other Race” category. For 

data product purposes, “Two or More Races” refers to combinations of two or more of the following race 

categories: 

1. White 

2. Black or African American 

3. American Indian or Alaska Native 

4. Asian 

5. Native Hawaiian or Other Pacific Islander 

6. Some Other Race 

There are 57 possible combinations (see Figure B-1) involving the race categories shown above. Thus, 

according to this approach, a response of “White” and “Asian” was tallied as Two or More Races, while 

a response of “Japanese” and “Chinese” was not because “Japanese” and “Chinese” are both Asian 

responses.

Race Concepts

Given the many possible ways of displaying data on race, data products will provide varying levels of 

detail. There are several additional concepts used to display race information for the six major race 

categories (White; Black or African American; American Indian or Alaska Native; Asian; Native Hawaiian or 

Other Pacific Islander; and Some Other Race) and the various details within these groups. 

The concept “race alone” includes people who reported a single entry (e.g., Korean) and no other race, 

as well as people who reported two or more entries within the same major race group (e.g., Asian). For 

example, respondents who reported Korean and Vietnamese are part of the larger “Asian alone” race 

group.

The concept “race alone or in combination” includes people who reported a single race alone (e.g., Asian) 

and people who reported that race in combination with one or more of the other major race groups (e.g., 

White, Black or African American, American Indian and Alaska Native, Native Hawaiian and Other Pacific 

Islander, and Some Other Race). The concept “race alone or in combination” concept, therefore, represents 

the maximum number of people who reported as that race group, either alone or in combination with one 

or more additional race(s). The sum of the six individual race “alone-or-in-combination” categories may add 

to more than the total population because people who reported more than one race were tallied in each 

race category.

The concept “race alone or in any combination” applies only to detailed race groups, such as American 

Indian and Alaska Native tribes, detailed Asian groups, and detailed Pacific Islander groups. For example, 

Korean alone or in any combination includes people who reported a single response (e.g., Korean), people 

who reported Korean and another Asian group (e.g., Korean and Vietnamese), and people who reported 

Korean in combination with one or more other non-Asian race groups (e.g., White, Black or African 

American, American Indian and Alaska Native, Native Hawaiian and Other Pacific Islander, or Some Other 

Race).

Coding of Write-In Entries—The 2010 Census included an automated review, computer edit, and coding 

operation on a 100 percent basis for the write-in responses to the race question, similar to that used in 

Census 2000. There were two types of coding operations: 1) automated coding where a write-in response 

was automatically coded if it matched a write-in response already contained in a database known as the 

“master file” and 2) expert coding, which took place when a write-in response did not match an entry 

already on the master file and was sent to expert coders familiar with the subject matter. During the 

coding process, subject-matter specialists reviewed and coded written entries from the response areas on 

the race question: American Indian or Alaska Native, Other Asian, Other Pacific Islander, and Some Other 

Race. Up to 30 text characters were collected from each race write-in area, and up to two responses were 

coded and tabulated from each separate race write-in area.

Comparability—There are three changes to the race question for the 2010 Census. First, the note to 

respondents was changed to read, “Please answer BOTH Question 8 about Hispanic origin and Question 9 

about race. For this census, Hispanic origins are not races.” Second, the wording of the race question was 

changed from “What is this person’s race? Mark ý one or more races to indicate what this person considers 

Figure B-1. 

Two or More Races (57 Possible Specified Combinations)—Con.
Definitions of Subject Characteristics B-13

U.S. Census Bureau, 2010 Census Summary File 1

himself/herself to be” to “What is Person 1’s race? Mark ý one or more boxes.” Third, examples were added 

to the “Other Asian” response categories (Hmong, Laotian, Thai, Pakistani, Cambodian, and so on) and the 

“Other Pacific Islander” response categories (Fijian, Tongan, and so on). 

The treatment of ethnic or national origin write-in responses to the race question also was different. For 

Census 2000, data on single ancestry by race from the 1990 census were used to help make decisions 

about how to code ethnic or national origin responses into one or more race categories. Essentially, if 90 

percent or more of people who reported a single, specific ancestry reported in a specific race category in 

1990 (e.g., more than 90 percent of people indicating Haitian ancestry reported as Black in the question 

on race), then that race was used as the Census 2000 response. This 90 percent rule was not applied to 

write-in responses of American Indian and Alaska Native tribes, Asian groups, or Pacific Islander groups 

because the question on race was designed explicitly to obtain these types of responses. For example, a 

write-in response of “Haitian and Moroccan” was coded as “Black” and “Some Other Race.” “Moroccan” was 

coded as “Some Other Race” because less than 90 percent of people indicating Moroccan ancestry reported 

in one specific race category in the question on race. 

For the 2010 Census, ethnic or national origin write-in responses to the race question were coded into 

one or more of the five OMB race categories, according to the 1997 OMB definitions of race. For example, 

a 2010 Census write-in response of “Haitian and Moroccan” was coded as “Black” and “White” following 

OMB’s definitions. If it was not possible to determine which OMB race category the ethnic group or national 

origin should be coded into, it was included in the “Some Other Race” category.

Sex

Individuals were asked to mark either “male” or “female” to indicate their sex. For most cases in which 

sex was not reported, the appropriate entry was determined from the person’s given (i.e., first) name and 

household relationship. Otherwise, sex was allocated according to the relationship to the householder and 

the age of the person. (For more information on allocation, see “2010 Census: Operational Overview and 

Accuracy of the Data.”)

Sex Ratio—The sex ratio represents the balance between the male and female populations. Ratios 

above 100 indicate a larger male population, and ratios below 100 indicate a larger female population. 

This measure is derived by dividing the total number of males by the total number of females and then 

multiplying by 100. It is rounded to the nearest tenth. 

Comparability—A question on the sex of individuals has been asked of the total population in every 

census.

LIVING QUARTERS

All living quarters are classified as either housing units or group quarters. Living quarters are usually 

found in structures that are intended for residential use, but they also may be found in structures intended 

for nonresidential use. Any place where someone lives is considered to be a living quarters, such as an 

apartment, dormitory, shelter for people experiencing homelessness, barracks, or nursing facility. Even 

tents, old railroad cars, and boats are considered to be living quarters if someone claims them as his or 
B-14 Definitions of Subject Characteristics

U.S. Census Bureau, 2010 Census Summary File 1

her residence. Note that structures that do not meet the definition of a living quarters at the time of listing 

may meet the definition at the time of enumeration. Some types of structures, such as those cited in items 

1 and 2 below, are included in address canvassing operations as place holders, with the final decision on 

their living quarters status made during enumeration. Other types of structures, such as those cited in 

items 3 and 4 below, are not included in the address canvassing operation. 

The following examples are not considered living quarters:

1. Structures, such as houses and apartments, that resemble living quarters but are being used entirely 

for nonresidential purposes, such as a store or an office, or used for the storage of business supplies 

or inventory, machinery, or agricultural products, are not enumerated. 

2. Single units as well as units in multiunit residential structures under construction in which no one is 

living or staying are not considered living quarters until construction has reached the point where all 

exterior windows and doors are installed and final usable floors are in place. Units that do not meet 

these criteria are not enumerated. 

3. Structures in which no one is living or staying that are open to the elements—that is, the roof, walls, 

windows, and/or doors no longer protect the interior from the elements—are not enumerated. Also, 

vacant structures with a posted sign indicating that they are condemned or they are to be demolished 

are not enumerated.

4. Boats, recreational vehicles (RVs), tents, caves, and similar types of shelter that no one is using as a 

usual residence are not considered living quarters and are not enumerated. 

Group Quarters

Group quarters are places where people live or stay in a group living arrangement, which are owned or 

managed by an entity or organization providing housing and/or services for the residents. This is not a 

typical household-type living arrangement. These services may include custodial or medical care as well as 

other types of assistance, and residency is commonly restricted to those receiving these services. People 

living in group quarters are usually not related to each other. 

Group quarters include such places as college residence halls, residential treatment centers, skilled-nursing 

facilities, group homes, military barracks, correctional facilities, and workers’ dormitories.

Institutional Group Quarters

Institutional group quarters (group quarters type codes 101–106, 201–203, 301, 401–405) are facilities 

that house those who are primarily ineligible, unable, or unlikely to participate in the labor force while 

residents. 

Correctional Facilities for Adults (codes 101–106)—Correctional facilities for adults include the 

following types:

Federal detention centers (code 101)—Federal detention centers are stand alone, generally multi-level, 

federally operated correctional facilities that provide “short-term” confinement or custody of adults 

pending adjudication or sentencing. These facilities may hold pretrial detainees, holdovers, sentenced 

offenders, and Immigration and Customs Enforcement (ICE) inmates, formerly called Immigration and 

Naturalization Service (INS) inmates. These facilities include Metropolitan Correctional Centers (MCCs), 

Metropolitan Detention Centers (MDCs), Federal Detention Centers (FDCs), Bureau of Indian Affairs 

Detention Centers, ICE Service Processing Centers, and ICE Contract Detention Facilities.

Federal (code 102) and state (code 103) prisons—Federal and state prisons are adult correctional 

facilities where people convicted of crimes serve their sentences. Common names include prison, 

penitentiary, correctional institution, federal or state correctional facility, and conservation camp. The 

prisons are classified by two types of control: 1) “federal” (operated by or for the Bureau of Prisons of 
Definitions of Subject Characteristics B-15

U.S. Census Bureau, 2010 Census Summary File 1

the U.S. Department of Justice) and 2) “state.” Residents who are forensic patients or criminally insane 

are classified on the basis of where they resided at the time of enumeration. Patients in hospitals (units, 

wings, or floors) operated by or for federal or state correctional authorities are counted in the prison 

population. Other forensic patients will be enumerated in psychiatric hospital units and floors for longterm non-acute patients. This category may include privately operated correctional facilities.

Local jails and other municipal confinement facilities (code 104)—Local jails and other municipal 

confinement facilities are correctional facilities operated by or for counties, cities, and American Indian 

and Alaska Native tribal governments. These facilities hold adults detained pending adjudication and/

or people committed after adjudication. This category also includes work farms and camps used to hold 

people awaiting trial or serving time on relatively short sentences. Residents who are forensic patients 

or criminally insane are classified on the basis of where they resided at the time of enumeration. 

Patients in hospitals (units, wings, or floors) operated by or for local correctional authorities are counted 

in the jail population. Other forensic patients will be enumerated in psychiatric hospital units and 

floors for long-term non-acute care patients. This category may include privately operated correctional 

facilities.

Correctional residential facilities (code 105)—Correctional residential facilities are community-based 

facilities operated for correctional purposes. The facility residents may be allowed extensive contact 

with the community, such as for employment or attending school, but are obligated to occupy the 

premises at night. Examples of correctional residential facilities are halfway houses, restitution centers, 

and prerelease, work release, and study centers.

Military disciplinary barracks and jails (code 106)—Military disciplinary barracks and jails are 

correctional facilities managed by the military to hold those awaiting trial or convicted of crimes.

Juvenile Facilities (codes 201–203)—Juvenile facilities include the following: 

Group homes for juveniles (non-correctional) (code 201)—Group homes for juveniles include communitybased group living arrangements for youth in residential settings that are able to accommodate three 

or more clients of a service provider. The group home provides room and board and services, including 

behavioral, psychological, or social programs. Generally, clients are not related to the caregiver or to 

each other. Examples of non-correctional group homes for juveniles are maternity homes for unwed 

mothers, orphanages, and homes for abused and neglected children in need of services. Group homes 

for juveniles do not include residential treatment centers for juveniles or group homes operated by or 

for correctional authorities.

Residential treatment centers for juveniles (non-correctional) (code 202)—Residential treatment centers 

for juveniles include facilities that provide services primarily to youth on-site in a highly structured 

live-in environment for the treatment of drug/alcohol abuse, mental illness, and emotional/behavioral 

disorders. These facilities are staffed 24 hours a day. The focus of a residential treatment center is on 

the treatment program. Residential treatment centers for juveniles do not include facilities operated by 

or for correctional authorities.

Correctional facilities intended for juveniles (code 203)—Correctional facilities intended for juveniles 

include specialized facilities that provide strict confinement for their residents and detain juveniles 

awaiting adjudication, commitment or placement, and/or those being held for diagnosis or 

classification. Also included are correctional facilities where residents are permitted contact with the 

community for purposes such as attending school or holding a job. Examples of correctional facilities 

intended for juveniles are residential training schools and farms, reception and diagnostic centers, 

group homes operated by or for correctional authorities, detention centers, and boot camps for juvenile 

delinquents.

Nursing Facilities/Skilled-Nursing Facilities (code 301)—Nursing facilities/Skilled-nursing facilities 

include facilities licensed to provide medical care with 7-day, 24-hour coverage for people requiring 
B-16 Definitions of Subject Characteristics

U.S. Census Bureau, 2010 Census Summary File 1

long-term non-acute care. People in these facilities require nursing care, regardless of age. Either of these 

types of facilities may be referred to as nursing homes.

Other Institutional Facilities (codes 401–405)—Other institutional facilities include the following:

Mental (psychiatric) hospitals and psychiatric units in other hospitals (code 401)—Mental (psychiatric) 

hospitals and psychiatric units in other hospitals include psychiatric hospitals, units and floors for 

long-term non-acute care patients. The primary function of the hospital, unit, or floor is to provide 

diagnostic and treatment services for long-term non-acute patients who have psychiatric-related illness. 

All patients are enumerated in this category.

Hospitals with patients who have no usual home elsewhere (code 402)—Hospitals with patients who 

have no usual home elsewhere include hospitals that have any patients who have no exit or disposition 

plan, or who are known as “boarder patients” or “boarder babies.” All hospitals are eligible for inclusion 

in this category except psychiatric hospitals, units, wings, or floors operated by federal, state, or local 

correctional authorities. Patients in hospitals operated by these correctional authorities will be counted 

in the prison or jail population. Psychiatric units and hospice units in hospitals are also excluded. Only 

patients with no usual home elsewhere are enumerated in this category.

In-patient hospice facilities (both free-standing and units in hospitals) (code 403)—In-patient hospice 

facilities (both free-standing and units in hospitals) include facilities that provide palliative, comfort, and 

supportive care for terminally ill patients and their families. Only patients with no usual home elsewhere 

are tabulated in this category.

Military treatment facilities with assigned patients (code 404)—Military treatment facilities with assigned 

patients include military hospitals and medical centers with active duty patients assigned to the facility. 

Only these patients are enumerated in this category.

Residential schools for people with disabilities (code 405)—Residential schools for people with 

disabilities include schools that provide the teaching of skills for daily living, education programs, and 

care for students with disabilities in a live-in environment. Examples of residential schools for people 

with disabilities are residential schools for the physically or developmentally disabled.

Noninstitutional Group Quarters

Noninstitutional group quarters (group quarters type codes 501, 601, 602, 701, 702, 704, 706, 801, 802, 

900, 901, 903, 904) are facilities that house those who are primarily eligible, able, or likely to participate 

in the labor force while residents.

College/University Student Housing (code 501)—College/University student housing includes 

residence halls and dormitories, which house college and university students in a group living 

arrangement. These facilities are owned, leased, or managed either by a college, university, or seminary, or 

by a private entity or organization. Fraternity and sorority housing recognized by the college or university 

are included as college student housing. However, students attending the U.S. Naval Academy, U.S. Military 

Academy (West Point), U.S. Coast Guard Academy, and U.S. Air Force Academy are counted in military 

group quarters.

Military Quarters (codes 601 and 602)—Military quarters (code 601) are facilities that include military 

personnel living in barracks (including “open” barrack transient quarters) and dormitories and military 

ships (code 602). Patients assigned to Military Treatment Facilities and people being held in military 

disciplinary barracks and jails are not enumerated in this category. Patients in Military Treatment Facilities 

with no usual home elsewhere are not enumerated in this category.

Other Noninstitutional Facilities (codes 701, 702, 704, 706, 801, 802, 900, 901, 903, and 

904)—Other noninstitutional facilities include the following:
Definitions of Subject Characteristics B-17

U.S. Census Bureau, 2010 Census Summary File 1

Emergency and transitional shelters (with sleeping facilities) for people experiencing homelessness 

(code 701)—Emergency and transitional shelters (with sleeping facilities) for people experiencing 

homelessness are facilities where people experiencing homelessness stay overnight. These include:

1. Shelters that operate on a first-come, first-serve basis where people must leave in the morning and 

have no guaranteed bed for the next night.

2. Shelters where people know that they have a bed for a specified period of time (even if they leave 

the building every day). 

3. Shelters that provide temporary shelter during extremely cold weather (such as churches). This 

category does not include shelters that operate only in the event of a natural disaster. 

Examples are emergency and transitional shelters; missions; hotels and motels used to shelter people 

experiencing homelessness; shelters for children who are runaways, neglected, or experiencing 

homelessness; and similar places known to have people experiencing homelessness.

Soup kitchens, regularly scheduled mobile food vans, and targeted non-sheltered outdoor locations 

(codes 702, 704, and 706)—This category includes soup kitchens that offer meals organized as food 

service lines or bag or box lunches for people experiencing homelessness; street locations where 

mobile food vans regularly stop to provide food to people experiencing homelessness; and targeted 

non-sheltered outdoor locations where people experiencing homelessness live without paying to 

stay. This also would include persons staying in pre-identified car, recreational vehicle (RV), and tent 

encampments. Targeted non-sheltered outdoor locations must have a specific location description; for 

example, “the Brooklyn Bridge at the corner of Bristol Drive,” “the 700 block of Taylor Street behind the 

old warehouse,” or the address of the parking lot being utilized. 

Group homes intended for adults (code 801)—Group homes intended for adults are community-based 

group living arrangements in residential settings that are able to accommodate three or more clients 

of a service provider. The group home provides room and board and services, including behavioral, 

psychological, or social programs. Generally, clients are not related to the caregiver or to each other. 

Group homes do not include residential treatment centers or facilities operated by or for correctional 

authorities.

Residential treatment centers for adults (code 802)—Residential treatment centers for adults provide 

treatment on-site in a highly structured live-in environment for the treatment of drug/alcohol abuse, 

mental illness, and emotional/behavioral disorders. They are staffed 24 hours a day. The focus of a 

residential treatment center is on the treatment program. Residential treatment centers do not include 

facilities operated by or for correctional authorities.

Maritime/Merchant vessels (code 900)—Maritime/merchant vessels include U.S. owned and operated 

flag vessels used for commercial or noncombatant government-related purposes at U.S. ports, on the 

sea, or on the Great Lakes.

Workers’ group living quarters and Job Corps centers (code 901)—Workers’ group living quarters and 

Job Corps centers include facilities such as dormitories, bunkhouses, and similar types of group living 

arrangements for agricultural and non-agricultural workers. This category also includes facilities that 

provide a full-time, year-round residential program offering a vocational training and employment 

program that helps young people 16 to 24 years old learn a trade, earn a high school diploma or 

GED, and get help finding a job. Examples are group living quarters at migratory farm-worker camps, 

construction workers’ camps, Job Corps centers, and vocational training facilities.

Living quarters for victims of natural disasters (code 903)—Living quarters for victims of natural 

disasters are temporary group living arrangements established as a result of natural disasters.

Religious group quarters and domestic violence shelters (code 904)—Religious group quarters are living 

quarters owned or operated by religious organizations that are intended to house their members in 
B-18 Definitions of Subject Characteristics

U.S. Census Bureau, 2010 Census Summary File 1

a group living situation. This category includes such places as convents, monasteries, and abbeys. 

Living quarters for students living or staying in seminaries are classified as college student housing, 

not religious group quarters. Domestic violence shelters are community-based homes, shelters, or crisis 

centers that provide housing for people who have sought shelter from household violence and who may 

have been physically abused.

Comparability—Due to the consolidation of group quarters types and general streamlining of the 

definitions, several changes have been implemented in the 2010 Census group quarters definitions and 

type codes that are reflected in 2010 Census data products. 

As in Census 2000, group quarters are either institutional group quarters or noninstitutional group 

quarters. 

Institutional group quarters are facilities that house those who are primarily ineligible, unable, or unlikely 

to participate in the labor force while residents. This definition has been simplified since the 1990 

and 2000 Censuses (both used the same definition, which focused on institutions providing formally 

authorized, supervised care or custody) to focus on labor force participation.

The phrase “institutionalized persons” in the 1990 Census data was changed to “institutionalized 

population” in Census 2000 and continues in the 2010 Census. 

Correctional facilities for adults—In the 2010 Census data products, the Census 2000 term “other type of 

correctional institutions” is categorized as “correctional residential facilities.” 

Juvenile facilities—Those group quarters categorized as “homes for abused, dependent, and neglected 

children” (public, private, or ownership unknown) in the Census 2000 data products are categorized as 

“group homes for juveniles (non-correctional)” in the 2010 Census data products. Those categorized in 

“training schools” (public, private, and ownership unknown), “detention centers, reception or diagnostic 

centers,” and “type of juvenile institution unknown” in Census 2000 data products are categorized in the 

2010 Census data products as “correctional facilities intended for juveniles” (i.e., training schools and 

farms, reception and diagnostic centers, detention centers, boot camps and group homes operated by or 

for correctional authorities). 

Nursing facilities/skilled-nursing facilities—In the 2010 Census data products, all nursing homes are 

categorized as “nursing facilities/skilled-nursing facilities.” 

Other institutional facilities—Those group quarters categorized as “schools, hospitals, or wards for the 

physically handicapped” in Census 2000 data products are categorized as “residential schools for people 

with disabilities” in the 2010 Census data products. “Military hospitals or wards for chronically ill” are 

classified as “military treatment facilities with assigned patients” in the 2010 Census data products. Also, 

what were called “military hospitals with patients who have no usual home elsewhere” in Census 2000 

data products are categorized as “hospitals with patients who have no usual home elsewhere” in 2010 

Census data products. “Hospices or homes for the chronically ill or other hospitals or wards for chronically 

ill” are categorized in the 2010 Census data products as “in-patient hospice facilities.” “Hospitals and wards 

for drug/alcohol abuse” and “mentally ill (psychiatric) hospitals or wards” are categorized in the 2010 

Census data products as “mental (psychiatric) hospitals and psychiatric units in other hospitals.”

The phrase “staff residents” was used for staff living in institutions in both the 1990 and 2000 Censuses. 

In Census 2000, staff living in institutions included those living in “agricultural workers’ dormitories,” 

“other workers’ dormitories,” “Job Corps and vocational training facilities,” “dormitories for nurses and 

interns in military hospitals,” and “dormitories for nurses and interns in general hospitals.” In the 2010 

Census, all these groups are categorized as “workers’ group living quarters and Job Corps centers.” 

Noninstitutional group quarters—In the 1990 Census, the Census Bureau used the phrase “other persons 

in group quarters” for people living in noninstitutionalized group quarters. In 2000, this group was 

referred to for the first time as the “noninstitutionalized population.” In 2010, this population continues 
Definitions of Subject Characteristics B-19

U.S. Census Bureau, 2010 Census Summary File 1

to be referred to as the noninstitutionalized population. Noninstitutional group quarters are facilities that 

house those who are primarily eligible, able, or likely to participate in the labor force while a resident.

As of Census 2000, the Census Bureau dropped the rule of classifying ten or more unrelated people living 

together as living in noninstitutional group quarters. This rule was used in the 1990 and 1980 Censuses. 

In the 1970 Census, the criteria was six or more unrelated people.

College/University student housing—In the 2010 Census, residence halls and dormitories, which house 

college and university students in a group living arrangement, may be owned, leased, or managed either 

by a college, university, or seminary or by a private entity or organization. In Census 2000, these types of 

facilities had to be owned by the college or university.

Military quarters—In 1960 data products, people in military barracks were shown only for men. Starting 

in 1970 and to the present, data are available for both men and women in military barracks. What were 

classified as “transient quarters for temporary residents (military or civilian)” in Census 2000 data products 

no longer include the civilian population, and the military residents are tabulated in “military quarters” in 

2010 Census data products.

Other noninstitutional facilities—In the 2010 Census, “workers group living quarters and Job Corps 

centers” are comprised of the following Census 2000 group quarters types: “agriculture workers’ 

dormitories,” “other workers’ dormitories,” “Job Corps and vocational training facilities,” and “dormitories 

for nurses and interns in hospitals (general and military).” As in Census 2000 and also in 1990, workers’ 

dormitories were classified as group quarters regardless of the number of people sharing the dormitory. In 

1980, ten or more unrelated people had to share the dorm for it to be classified as a group quarters. 

In the 2010 Census, “emergency and transitional shelters (with sleep facilities) for people experiencing 

homelessness” includes the Census 2000 categories “emergency and transitional shelters” and “shelters for 

children who are runaways, neglected, or without conventional housing.” 

In the 2010 Census, “religious group quarters” are combined with “shelters for abused women (or shelters 

against domestic violence)” to make the category “religious group quarters and domestic violence 

shelters.”

In the 2010 Census data products, the category “group homes intended for adults (non-correctional)” 

consists of the following group quarters types (as listed in Census 2000): “homes for the mentally ill,” 

“homes for the mentally retarded,” “homes for the physically handicapped,” “residential care facilities 

providing protective oversight,” and “other group homes.” “Homes or halfway houses for drug/alcohol 

abuse” are categorized as “residential treatment centers for adults (non-correctional).” 

The following group quarters types that were included in Census 2000 are no longer classified as group 

quarters in the 2010 Census: “military hotels/campgrounds,” “transient locations,” and “other household 

living situations ‘–dangerous encampments.’”

Like in Census 2000, rooming and boarding houses are classified as housing units in the 2010 Census. In 

the 1990 Census, these were considered group quarters.

Housing Units

A housing unit is a living quarters in which the occupant or occupants live separately from any other 

individuals in the building and have direct access to their living quarters from outside the building or 

through a common hall. Housing units are usually houses, apartments, mobile homes, groups of rooms, 

or single rooms that are occupied as separate living quarters. They are residences for single individuals, 

groups of individuals, or families who live together. A single individual or a group living in a housing unit 

is defined to be a household. Additional details about housing for the elderly population and group homes 

are provided in the section “Housing for the Older Population.”
B-20 Definitions of Subject Characteristics

U.S. Census Bureau, 2010 Census Summary File 1

For vacant housing units, the criteria of separateness and direct access are applied to the intended 

occupants whenever possible. Nontraditional living quarters such as boats, RVs, and tents are considered 

to be housing units only if someone is living in them and they are either the occupant’s usual residence 

or the occupant has no usual residence elsewhere. These nontraditional living arrangements are not 

considered to be housing units if they are vacant.

Housing units are classified as being either occupied or vacant. 

Occupied Housing Unit—A housing unit is classified as occupied if it is the usual place of residence of 

the individual or group of individuals living in it on Census Day, or if the occupants are only temporarily 

absent, such as away on vacation, in the hospital for a short stay, or on a business trip, and will be 

returning.

The occupants may be an individual, a single family, two or more families living together, or any other 

group of related or unrelated individuals who share living arrangements.

Occupied rooms or suites of rooms in hotels, motels, and similar places are classified as housing units 

only when occupied by permanent residents; that is, occupied by individuals who consider the hotel their 

usual place of residence or who have no usual place of residence elsewhere. However, when rooms in 

hotels and motels are used to provide shelter for people experiencing homelessness, they are not housing 

units. Rooms used in this way are considered group quarters. 

Vacant Housing Unit—A housing unit is classified as vacant if no one is living in it on Census Day, unless 

its occupant or occupants are only temporarily absent—such as away on vacation, in the hospital for a 

short stay, or on a business trip—and will be returning.

Housing units temporarily occupied at the time of enumeration entirely by individuals who have a usual 

residence elsewhere are classified as vacant. When housing units are vacant, the criteria of separateness 

and direct access are applied to the intended occupants whenever possible. If that information cannot be 

obtained, the criteria are applied to the previous occupants.

Boats, RVs, tents, caves, and similar shelter that no one is using as a usual residence are not considered 

living quarters and therefore are not enumerated at all. 

Housing for the Older Population—Housing specifically for the older population has become more 

and more prevalent and is being identified by many different names. Living quarters in these facilities, 

unless they meet the definition of skilled nursing facilities, are housing units, with each resident’s living 

quarters considered a separate housing unit if it meets the housing unit definition of direct access. These 

residential facilities may be referred to as senior apartments, active adult communities, congregate care, 

continuing care retirement communities, independent living, board and care, or assisted living. People may 

have to meet certain criteria to be able to live in these facilities, but once accepted as residents they have 

unrestricted access to and from their units to the outside.

Housing units and group quarters may coexist under the same entity or organization and in some 

situations, actually share the same structure. An assisted living facility complex may have a skilled nursing 

floor or wing that meets the definition of a nursing facility and is, therefore, a group quarters, while the 

rest of the living quarters in the facility are considered to be housing units. Congregate care facilities 

and continuing care retirement communities often consist of several different types of living quarters, 

with varying services and levels of care. Some of the living quarters in these facilities and communities 

are considered to be housing units and some are considered to be group quarters, depending on which 

definition they meet. 

Comparability—The first Census of Housing in 1940 established the “dwelling unit” concept. Although 

the term became “housing unit” and the definition was modified slightly in succeeding censuses, the 

housing unit definition remained essentially comparable between 1940 and 1990. Since 1990, two 

changes were made to the housing unit definition. 
Definitions of Subject Characteristics B-21

U.S. Census Bureau, 2010 Census Summary File 1

The first change eliminated the concept of “eating separately.” The elimination of the eating criterion is 

more in keeping with the United Nations’ definition of a housing unit that stresses the entire concept 

of separateness rather than the specific “eating” element. Although the “eating separately” criterion 

previously was included in the definition of a housing unit, the data needed to distinguish whether the 

occupants ate separately from any other people in the building were not collected. (Questions that asked 

households about their eating arrangements have not been included in the census since 1970.) Therefore, 

the current definition better reflects the information that is used in the determination of a housing unit.

The second change for Census 2000 and the 2010 Census eliminated the “number of nonrelatives” 

criterion; that is, “9 or more people unrelated to the householder” which caused a conversion of housing 

units to group quarters. This change was prompted by the following considerations: 1) there were 

relatively few such conversions made as a result of this rule in 1990; 2) household relationship and 

housing data were lost by converting these units to group quarters; and 3) there was no empirical support 

for establishing a particular number of nonrelatives as a threshold for these conversions.

In 1960, 1970, and 1980, vacant rooms in hotels, motels, and other similar places where 75 percent or 

more of the accommodations were occupied by permanent residents were counted as part of the housing 

inventory. However, an evaluation of the data collection procedures prior to the 1990 Census indicated 

that the concept of permanency was a difficult and confusing procedure for enumerators to apply 

correctly. Consequently, in the 1990 Census, vacant rooms in hotels, motels, and similar places were not 

counted as housing units. In Census 2000 and the 2010 Census, we continued the procedure adopted in 

1990. 

HOUSING CHARACTERISTICS

Household Size

This question is based on the count of people in occupied housing units. All people occupying the housing 

unit are counted, including the householder, occupants related to the householder, and lodgers, roomers, 

boarders, and so forth. 

Average Household Size of Occupied Unit—The average household size of an occupied unit is a 

measure obtained by dividing the number of people living in occupied housing units by the total number 

of occupied housing units. This measure is rounded to the nearest hundredth. 

Average Household Size of Owner-Occupied Unit—The average household size of an owner-occupied 

unit is a measure obtained by dividing the number of people living in owner-occupied housing units by the 

total number of owner-occupied housing units. This measure is rounded to the nearest hundredth. 

Average Household Size of Renter-Occupied Unit—The average household size of a renter-occupied 

unit is a measure obtained by dividing the number of people living in renter-occupied housing units by the 

total number of renter-occupied housing units. This measure is rounded to the nearest hundredth. 

Tenure

Tenure was asked at all occupied housing units. All occupied housing units are classified as either owneroccupied or renter-occupied. 

Owner-Occupied—A housing unit is owner-occupied if the owner or co-owner lives in the unit even if it 

is mortgaged or not fully paid for. The owner or co-owner must live in the unit and usually is Person 1 on 

the questionnaire. The unit is “Owned by you or someone in this household with a mortgage or loan” if it 

is being purchased with a mortgage or some other debt arrangement, such as a deed of trust, trust deed, 

contract to purchase, land contract, or purchase agreement. The unit is also considered owned with a 

mortgage if it is built on leased land and there is a mortgage on the unit. 

A housing unit is “Owned by you or someone in this household free and clear (without a mortgage or 

loan)” if there is no mortgage or other similar debt on the house, apartment, or mobile home, including 
B-22 Definitions of Subject Characteristics

U.S. Census Bureau, 2010 Census Summary File 1

units built on leased land if the unit is owned outright without a mortgage. Although most tables show 

total owner-occupied counts, selected tables separately identify the two owner categories. 

Renter-Occupied—All occupied housing units which are not owner-occupied, whether they are rented or 

occupied without payment of rent, are classified as renter-occupied. “Rented” includes units in continuing 

care, sometimes called life care arrangements. These arrangements usually involve a contract between 

one or more individuals and a service provider guaranteeing the individual shelter, usually an apartment, 

and services, such as meals or transportation to shopping or recreation. The “no rent paid” category 

includes units provided free by friends or relatives or in exchange for services, such as a resident manager, 

caretaker, minister, or tenant farmer. Housing units on military bases are also classified in the “No rent 

paid” category. 

Comparability—Data on tenure have been collected since 1890. In 1990, the response categories were 

expanded to allow the respondent to report whether the unit was owned with a mortgage or loan, or free 

and clear (without a mortgage). The distinction between units owned with a mortgage and units owned 

free and clear was added in 1990 to improve the count of owner-occupied units. Research after the 1980 

Census indicated some respondents did not consider their units owned if they had a mortgage. In Census 

2000, we continued with the same tenure categories used in the 1990 Census. In 2010, the instruction 

“Include home equity loans” was added following the response category “Owned by you or someone in this 

household with a mortgage or loan?” Additional changes included revising the wording of two response 

categories from “Rented for cash rent?” to “Rented?” and “Occupied without payment of cash rent?” to 

“Occupied without payment of rent?” 

Vacancy Status

The data on vacancy status were obtained from Enumerator Questionnaire item C. Vacancy status and 

other characteristics of vacant units were determined by census enumerators obtaining information from 

landlords, owners, neighbors, rental agents, and others. Vacant units are subdivided according to their 

housing market classification as follows: 

For Rent—These are vacant units offered “for rent” and vacant units offered either “for rent” or “for 

sale.” 

Rented, Not Occupied—These are vacant units rented but not yet occupied, including units where 

money has been paid or agreed upon, but the renter has not yet moved in.

For Sale Only—These are vacant units being offered “for sale only,” including units in cooperatives and 

condominium projects if the individual units are offered “for sale only.” If units are offered either “for 

rent” or “for sale,” they are included in the “for rent” classification. 

Sold, Not Occupied—These are vacant units sold but not yet occupied, including units that have been 

sold recently, but the new owner has not yet moved in.

For Seasonal, Recreational, or Occasional Use—These are vacant units used or intended for use 

only in certain seasons or for weekends or other occasional use throughout the year. Seasonal units 

include those used for summer or winter sports or recreation, such as beach cottages and hunting 

cabins. Seasonal units also may include quarters for such workers as herders and loggers. Interval 

ownership units, sometimes called shared-ownership or time-sharing condominiums, also are included 

here. 

For Migrant Workers—These include vacant units intended for occupancy by migratory workers 

employed in farm work during the crop season. (Work in a cannery, freezer plant, or food-processing 

plant is not farm work.)

Other Vacant—If a vacant unit does not fall into any of the categories specified above, it is classified 

as “Other vacant.” For example, this category includes units held for occupancy by a caretaker or janitor 

and units held for personal reasons of the owner.
Definitions of Subject Characteristics B-23

U.S. Census Bureau, 2010 Census Summary File 1

Homeowner Vacancy Rate—The homeowner vacancy rate is the proportion of the homeowner inventory 

that is vacant “for sale.” It is computed by dividing the number of vacant units “for sale only” by the sum 

of the owner-occupied units, vacant units that are “for sale only,” and vacant units that have been sold but 

not yet occupied, and then multiplying by 100. This measure is rounded to the nearest tenth. 

Rental Vacancy Rate—The rental vacancy rate is the proportion of the rental inventory that is vacant “for 

rent.” It is computed by dividing the number of vacant units “for rent” by the sum of the renter-occupied 

units, vacant units that are “for rent,” and vacant units that have been rented but not yet occupied, and 

then multiplying by 100. This measure is rounded to the nearest tenth. 

Available Housing Vacancy Rate—The available housing vacancy rate is the proportion of the housing 

inventory that is vacant-for-sale only and vacant-for-rent. It is computed by dividing the sum of vacant-forsale-only housing units and vacant-for-rent housing units, by the sum of occupied units, vacant-for-saleonly housing units, vacant-sold-not-occupied housing units, vacant-for-rent housing units, and vacantrented-not-occupied housing units, and then multiplying by 100. This measure is rounded to the nearest 

tenth. 

Comparability—Data on vacancy status have been collected since 1940. Since 1990, we have used the 

category “For seasonal, recreational, or occasional use.” In earlier censuses, separate categories were used 

to collect data on these types of vacant units. Also, in 1970 and 1980, housing characteristics generally 

were presented only for year-round units. Beginning in 1990 and continuing into Census 2000, housing 

characteristics are shown for all housing units. Census 2000 used a single vacancy status category for 

units that were either “Rented or sold, not occupied.” In 2010, we used two separate categories “Rented, 

not occupied” and “Sold, not occupied.” This change provided consistency with the American Community 

Survey and the Housing Vacancy Survey. These revised categories were incorporated in the calculations of 

the homeowner vacancy, rental vacancy, and the available housing vacancy rates. 

DERIVED MEASURES

Census data products include various derived measures, such as medians, means, and percentages, as 

well as certain rates and ratios. Derived measures that round to less than 0.1 are not shown but indicated 

as zero. 

Area Measurement and Density 

The 2010 Census summary file geographic header record provides the size, in square meters, of 

geographic entities for which the U.S. Census Bureau tabulates and disseminates data. Land area is shown 

in Field Name AREALAND (starting position 199) and water area in Field Name AREAWATR (starting position 

213). To convert square meters to square kilometers, divide by 1,000,000; to convert square kilometers to 

square miles, divide by 2.589988; to convert square meters to square miles, divide by 2,589,988. 

Population density (average number of people per square mile) is calculated by dividing the number of 

people in a specified geographic area by its land area in square miles. 

Housing unit density (average number of housing units per square mile) is calculated by dividing the 

number of housing units in a specified geographic area by its land area in square miles.

Average

See “Mean.”

Interpolation

Interpolation is frequently used to calculate medians or quartiles and to approximate standard errors 

from tables based on interval data. Different kinds of interpolation may be used to estimate the value 

of a function between two known values, depending on the form of the distribution. The most common 

distributional assumption is that the data are linear, resulting in linear interpolation. 
B-24 Definitions of Subject Characteristics

U.S. Census Bureau, 2010 Census Summary File 1

Mean

This measure represents an arithmetic average of a set of values. It is derived by dividing the sum (or 

aggregate) of a group of numerical items by the total number of items in that group. For example, average 

family size is obtained by dividing the number of people in families by the total number of families 

(or family householders). (Additional information on means and aggregates is included in the separate 

explanations of many of the population and housing subjects.) 

Median

This measure represents the middle value (if n is odd) or the average of the two middle values (if n is 

even) in an ordered list of n data values. The median divides the total frequency distribution into two 

equal parts: one-half of the cases falling below the median and one-half above the median. Each median is 

calculated using a standard distribution. The standard distribution for the calculation of median age is:

Age [116]

Under 1 year

1 year

2 years

3 years

4 years

5 years

.

.

.

112 years

113 years

114 years

115 years and over

(For more information, see “Interpolation.”) 

Jam values will be assigned whenever the median falls in an open-ended interval. For example, if the 

median age value fell in the open-ended category 115 years and over, the value displayed would be 115+. 

The presentation of jam values will vary between products and types of media. 

For data products displayed in American FactFinder, publications, or in display table format, medians 

that fall in the upper-most category of an open-ended distribution will be shown with a plus symbol (+) 

appended, and medians that fall in the lowest category of an open-ended distribution will be shown with a 

minus symbol (–) appended. For other data products and data files that are downloaded by users (i.e., FTP 

files), plus and minus signs will not be appended. 

Percentage

This measure is calculated by taking the number of items in a group possessing a characteristic of interest 

and dividing by the total number of items in that group, and then multiplying by 100. 

Rate

This is a measure of occurrences in a given period of time divided by the possible number of occurrences 

during that period. For example, the homeowner vacancy rate is calculated by dividing the number of 

vacant units “for sale only” by the sum of owner-occupied units, vacant units that are “for sale only,” and 

vacant units that have been sold but not yet occupied, and then multiplying by 100. Rates are sometimes 

presented as percentages.

2010 CENSUS MISSION AND SCOPE

Beginning with the Congressional Act of March 6, 1902, the U.S. Census Bureau was legally established as 

the “official” data collector for the United States of America. The Census Bureau routinely conducts multiple 

national, large-scale household surveys and censuses to provide the Administration; Congress; state, local, 

and tribal planners; the business community; trade associations; academicians; and other data users with 

a vast array of essential information. Most notable is the every 10-year (decennial) census of population 

and housing.

This section provides an overview of operations and systems in the 2010 Census of Population and 

Housing. To assist in understanding terms in the descriptions of many operations or to learn more 

about the 2010 Census, please refer to <www.2010census.gov> or the official 2010 Census glossary of 

acronyms, where detailed definitions of terms and acronyms can be found at <www.census.gov/dmd

/www/glossary.html>. Thumbnail descriptions are found in this section as well as the operational timeline 

for the operations and the contact information for the 12 regional offices.

The mission, upon which we define the requirements and build the systems, is “the 2010 Census will 

conduct a census of population and housing, and disseminate the data to the President, the States, and to 

the American people.” The scope of the 2010 Census is as follows: 

• The 2010 Census shall cover the 50 states, the District of Columbia, Puerto Rico, the U.S. Virgin 

Islands, the Commonwealth of the Northern Mariana Islands, Guam, the Pacific Island Area of American 

Samoa, and Federally Affiliated Americans overseas.

• The Census Day for the 2010 Census shall be April 1, 2010; have a boundary reference date of January 

1, 2010; and deliver apportionment counts to the President by December 31, 2010, and redistricting 

counts to the states by April 1, 2011. 

• The 2010 Census concludes upon delivery of all products and the subsequent headquarters closeout 

activities ending September 30, 2013.

The focus of this section is the 2010 Census. It does not include descriptions of the American Community 

Survey or the Master Address File/Topographically Integrated Geographic Encoding and Referencing

(MAF/TIGER®) database Enhancement Program. It should also be noted that from a strategy and

operational perspective, Puerto Rico is treated the same as the 50 States and the District of Columbia, with 

the exception of language (Spanish) and minor program modifications. 

SIX OPERATIONAL PLANNING CATEGORIES

The forty-four 2010 Census operations and operation groups are categorized into 1 of the 6 categories 

based on the similarity of their missions. High-level descriptions of the operational planning categories are: 

1. Provide Support—This category is concerned with supporting operations of the 2010 Census 

through the organization and operation of the census business processes that make the census 

mission possible. Activities include operational support, planning and management support, as 

well as infrastructure support and system design, development, and testing.

2. Establish Where to Count—This category is concerned with gathering and compiling the 

needed inputs to ensure the completeness of the geographic and address data that make up 

the framework for the census, as well as establishing the respondent data collection universe 

for the census itself. These activities provide the basis for the work done to collect respondent 

information.

3. Collect and Integrate Respondent Information—This category is concerned with the actual 

collection of census respondent information as derived through processing completed census 

forms delivered by the U.S. Postal Service or gathered through field enumeration activities.

4. Provide Census Results—This category is concerned with the refinement of collected census 

response data and dissemination of census results. Response data collected from census forms 

processing and field enumeration are refined and edited to produce an accurate count with 

complete data characteristics. These counts with characteristic data are then summarized, which 

removes personally identifiable information. A wide array of census products are then produced 

and disseminated.

5. Measure Census Coverage—This category includes coverage measurement operations that are 

separate from and independent of the census operations. They are designed to provide estimates 

of net coverage error and omissions and erroneous enumerations for persons in housing units and 

for the housing units themselves. These activities provide the needed inputs, which allow census 

coverage to be measured.

6. Analyze and Research the Census—This category includes 2010 Census assessments, 

evaluations, and experiments. Assessments are used to document final volumes and rates for 

individual operations or processes, using data from production files and activities; quality control 

files and activities; and information collected from debriefings and lessons learned. Evaluations 

analyze the outcomes of pre-specified census operations, such as the effectiveness of integrated 

communications. Experiments are studies that occur during the census to learn about new or 

different methodologies which inform the 2020 Census design.

1. Provide Support

The Provide Support operational planning category includes the operations that sustain the 2010 Census

Data Collection and Processing Procedures C-5

U.S. Census Bureau, 2010 Census Summary File 1

4. Provide Census Results

The Provide Census Results operational planning category is concerned with the refinement of the 

collected census response data and dissemination of census results. Response data collected from census 

forms processing and field enumeration are refined and edited to produce an accurate count with complete 

data characteristics. These counts with characteristic data are then summarized, which removes personally 

identifiable information. A wide array of census products are then produced and disseminated.

30. Geographic Boundary and Districting Operation—Determines and updates the geographic 

area boundaries for districting and tabulation. 

31. Response Processing Production Operation—Processes integrated response data provided 

by the DCI operation to unduplicate responses, ensure that complete information is collected, 

conduct statistical methods, and format data files used to produce census results.

32. Count Review Operation—Designed to enhance the accuracy of the census and provides the 

Federal-State Cooperative Program for Population Estimates (FSCPE) with the opportunity to review 

and provide feedback on count tabulations prior to the release of Public Law 94-171 data.

33. Data Products and Dissemination Production (DPD) Operation—Tabulates and disseminates 

2010 Census products, including apportionment counts and Public Law 94-171 redistricting data. 

The DPD produces many data products, including state and national summary files, tabulated 

informational files, and data comparison tables. The DPD is responsible for printed and electronic 

informational products that include population and housing unit tabulations, geographical maps, 

and a number of data products that specifically pertain to the island areas. 

The Data Access and Dissemination System (DADS) program is the primary provider of 

dissemination services via the Internet through the American FactFinder (AFF) system. This 

system was redesigned and enhanced for the 2010 Census and for dissemination of other Census 

Bureau data products. The DADS program is also the provider of tabulation services for the 

decennial census. Tabulation services refer to the activities related to aggregating data collected 

on individual responses to a survey or census into summarized statistical data suitable for public 

release. Dissemination services refer to the activities related to the internal staging and release 

of approved statistics for posting on the Internet. These services include the provision of interim 

results or output so that other areas of the Census Bureau can process and release data in different 

media and formats, (e.g. CD-ROM, DVD, File Transfer Protocol [FTP], Adobe Acrobat Portable 

Document Format [PDF] for printed publications). 

34. Archiving Operation—Provides 2010 Census records to the National Archives and Records 

Administration (NARA).

5. Measure Census Coverage

The Measure Census Coverage operational planning category includes coverage measurement operations 

that are separate from and independent of the census operations. They are designed to provide estimates 

of net coverage error and omissions and erroneous enumerations for persons in housing units and for the 

housing units themselves. These activities provide the needed inputs that allow census coverage to be 

measured. This planning category consists of the Census Coverage Measurement (CCM) program and the 

Demographic Analysis operation.

The focus of the CCM program is to measure the coverage error in the 2010 Census with the goal of 

improving future census operations. CCM produces estimates of net coverage error and estimates of 

the coverage error components for both housing units and persons living in housing units. Components 

of coverage error include omissions and erroneous enumerations (including duplicates). Measuring the 

coverage error of persons in group quarters and of group quarters facilities is not within the scope of the 
C-6 Data Collection and Processing Procedures

U.S. Census Bureau, 2010 Summary File 1

CCM program. The CCM is a sample survey and, as is typical, is conducted separately and independently 

of the census operations to ensure that the coverage error estimates are unbiased.

35. CCM Sample Design Operation—Designs and implements the sample to support the estimation 

of coverage errors in the 2010 Census for the United States and Puerto Rico, excluding remote 

Alaska. 

36. CCM Independent Listing Field Operation—Creates the list of CCM addresses by canvassing 

the selected sample block cluster areas using a paper instrument called the CCM Independent 

Listing Book (ILB).

37. CCM Initial Housing Unit Matching and Follow-Up Operation—Determines the reasons for 

differences between the housing unit addresses in the CCM sample and the initial census address 

list using automated computer matching, clerical matching, and in-person follow-up techniques.

38. CCM Person Interview Field Operation—Collects person and housing unit information for 

selected housing units in each sample block cluster by performing in-person interviews using a 

computer-assisted data collection instrument.

39. CCM Person Matching and Follow-Up Operation—Determines the reasons for the differences 

between the persons in the CCM sample and the persons in the 2010 Census using automated 

computer matching, clerical matching, telephone and in-person follow-up techniques.

40. CCM Final Housing Unit Matching and Follow-Up Operation—Determines the reasons for 

the differences between the housing unit addresses in the CCM sample and the final 2010 Census 

address list using automated computer matching, clerical matching, and in-person follow-up 

techniques.

41. CCM Estimation Operation—Produces estimates of net coverage error and the components 

of coverage error for housing units and persons living in housing units in the United States and 

Puerto Rico, excluding remote Alaska.

42. Demographic Analysis Operation—Produces independent assessments of census coverage 

using population and housing unit benchmarks in support of the 2010 Census and the evaluation 

of 2010 Census results.

6. Analyze and Research the Census

The Analyze and Research the Census operational planning category includes 2010 Census assessments, 

evaluations, and experiments. Assessments are used to document final volumes and rates for individual 

operations or processes, using data from production files and activities; quality control files and activities; 

and information collected from debriefings and lessons learned. Evaluations analyze the outcomes of 

prespecified census operations, such as the effectiveness of integrated communications. Experiments are 

studies that occur during the census to learn about new or different methodologies, which inform the 

2020 Census design.

43. Evaluations, Experiments, and Assessments Operation—Includes all of the analyses of 

the design and operations of the 2010 Census, as well as experimental design changes that 

could inform the 2020 Census. Evaluations and assessments are performed and experiments are 

conducted to analyze the 2010 Census and to inform early research in the 2020 Census test cycle.

44. Count Question Resolution Operation—Conducts an administrative review to handle 

external challenges to official 2010 Census counts of housing units and group quarters and their 

associated population.

INTRODUCTION

There are three large format map types that support the 2010 Census Summary File 1 Data Release. Each 

of these map types are produced in Adobe’s portable document format (PDF). These georeferenced PDF 

files are available through the U.S. Census Bureau’s Web site. In addition to the maps, other geographic 

products include the TIGER/Line Shapefiles, Census Block Relationship files, Census Tract Relationship files, 

and other Geographic Entity information. 

MAP DESCRIPTIONS

2010 Census—Census Block Map

The 2010 Census Block Map Series, also referred to as the Geographic Unit (GU) block maps, is produced 

to support the 2010 Decennial Census data release. These maps display tabulation geography down to 

the census block level. The 2010 Census Block Maps are produced for the following entities: counties 

and statistically equivalent entities, minor civil divisions (MCDs), census county divisions (CCDs) and 

statistically equivalent entities, incorporated places, census designated places (CDPs), consolidated cities, 

sub-MCDs, federal American Indian reservations, state American Indian reservations, Oklahoma tribal 

statistical areas (OTSAs), Alaska Native village statistical areas (ANVSAs), tribal designated statistical areas 

(TDSAs), state designated tribal statistical areas (SDTSAs), tribal subdivisions, and Hawaiian home lands 

(HHLs).

These large-scale maps show the boundaries and numbers for all census blocks within an entity. In 

addition to state and county, these maps show the boundaries, names and codes for American Indian 

areas, Alaska Native areas, Hawaiian home lands, county subdivisions, places and census tracts. These 

maps also show and label base features, such as roads, railroads and hydrography. The intent of this series 

is to show each entity on the fewest number of map sheets possible and at the maximum practical scale, 

depending on the size and shape of the entity and the density of the census blocks it contains. Census 

block density affects the display of the census blocks numbers and feature identifiers. Each entity is 

covered by one or more parent map sheets at a single scale. Inset map sheets at larger scales were created 

as required to show the map content described above. An index map showing the sheet configuration is 

included for all entities requiring more than one parent map sheet. The map sheet size is 36 x 32 inches.

Each map is accompanied by a Census Block to Map Sheet relationship file. These semicolon-delimited 

text files include a record for each census block within the entity, consisting of the corresponding state, 

county, census tract, and census block codes for the block and a list of all map sheet numbers that the 

block appears on for that map. When the map entity is a federal American Indian reservation or a tribal 

subdivision, the Census Block to Map Sheet relationship file also includes the related tribal census tract 

and tribal block group for each census block.

U.S. Census Bureau, 2010 Census Summary File 1

2010 Census—Census Tract Reference Map

These county-based reference maps show and label the census tracts as delineated to support 2010 

Census data dissemination. These maps also show the boundaries and names of American Indian areas, 

Alaska Native areas, Hawaiian home lands, counties, county subdivisions, and places. Additionally, these 

maps display a base feature network including roads, railroads, and water bodies. These features are 

labeled as map scale permits. The map sheet configuration is optimized to keep the number of map sheets 

for each county to a minimum. Each county will be covered by one or more parent map sheets at a single 

scale. Inset map sheets at larger scales are created where there are clusters of census tracts that cannot 

be identified at the parent map scale. An index map showing the sheet configuration is created for all 

counties requiring more than one parent map sheet. The map sheet size is 36 by 32 inches. 2010

2010 Census—School District Reference Map 

These reference maps show and label the unified, secondary, and elementary school districts as delineated 

by the state participants of the School District Review Program. These county-based maps also show and 

label states, counties, and places. Additionally, these maps display a base feature network including roads 

and water bodies. Major highways and selected water bodies are labeled. Each county will be covered by 

one or more parent map sheets at a single scale. Inset map sheets at larger scales are created where there 

are clusters of school districts that cannot be identified at the parent map scale. An index map showing 

the sheet configuration is created for all counties requiring more than one parent map sheet. For states 

and state-equivalents, including the District of Columbia, Florida, Hawaii, Maryland, Nevada, and West 

Virginia, where school districts are coextensive with counties, a state-based map identifying the counties 

and corresponding school districts is produced. The map sheet size is 36 by 32 inches.

WHERE YOU ARE COUNTED IS IMPORTANT

For the 2010 Census, the U.S. Census Bureau is committed to counting every person. Just as important, 

however, is the Census Bureau’s commitment to counting every person in the correct place. The 

fundamental reason the decennial census is conducted is to fulfill the constitutional requirement 

(Article I, Section 2) to apportion the seats in the U.S. House of Representatives among the states. Thus, 

for a fair and equitable apportionment, it is crucial that people are counted in the right place during the 

2010 Census. 

THE CONCEPT OF USUAL RESIDENCE

Planners of the first U.S. decennial census in 1790 established the concept of “usual residence” as the 

main principle in determining where people were to be counted. This concept has been followed in all 

subsequent censuses and is the guiding principle for the 2010 Census. Usual residence is defined as the 

place where a person lives and sleeps most of the time. This place is not necessarily the same as the 

person’s voting residence or legal residence. 
G-2 Residence Rule & Residence Situations for the 2010 Census of the United States

U.S. Census Bureau, 2010 Census Summary File 1

Determining usual residence is easy for most people. Given our nation’s wide diversity in types of living 

arrangements, however, the usual residence for some people is not as apparent. A few examples are 

people experiencing homelessness, snowbirds, children in shared custody arrangements, college students, 

live-in employees, military personnel, and people who live in workers’ dormitories. 

Applying the usual residence concept to real living situations means that people will not always be 

counted at the place where they happen to be staying on Thursday, April 1, 2010 (Census Day). For 

example, people who are away from their usual residence while on vacation or on a business trip on 

Census Day should be counted at their usual residence. People who live at more than one residence during 

the week, month, or year should be counted at the place where they live most of the time. People without 

a usual residence, however, should be counted where they are staying on Census Day. 

THE RESIDENCE RULE

The residence rule is used to determine where people should be counted in the United States during the 

2010 Census. The rule says:

▪ Count people at their usual residence, which is the place where they live and sleep most of the time. 

▪ People in certain types of facilities or shelters (i.e., places where groups of people live together) on 

Census Day should be counted at the facility or shelter. 

▪ People who do not have a usual residence, or cannot determine a usual residence, should be counted 

where they are on Census Day.

This residence rule also is used to determine where people are counted in the 2010 Census of Puerto Rico.

The following sections describe how the residence rule applies for people in various living situations. 

PEOPLE AWAY FROM THEIR USUAL RESIDENCE ON CENSUS DAY
