INTRODUCTION

Data from the 2010 Census for the United States and Puerto Rico are presented in two printed report series 

and a single report for American Indians and Alaska Natives by tribe:

1. CPH-1, Summary Population and Housing Characteristics

2. CPH-2, Population and Housing Unit Counts

3. CPH-3, Characteristics of American Indians and Alaska Natives by Tribe 

The data from the 2010 Census were derived from a limited number of basic questions asked of the entire 

population and about every housing unit. Appendix D (see Selected Appendixes report at <www.census

.gov/prod/cen2010/cph-2-a.pdf>) presents a facsimile of the questionnaire pages used to collect the data 

included in this report. Note that the “long form” data included in previous censuses are not included in 

the 2010 Census. 

The CPH-1, Summary Population and Housing Characteristics, report series provides data based on age, 

Hispanic or Latino origin, household relationship, race, sex, tenure (owner- or renter-occupied), and 

vacancy characteristics. Land area measurements and population density also are provided. This series is 

similar to the Census 2000 PHC-1 series. 

The CPH-2, Population and Housing Unit Counts, report series provides 2010 Census and historical comparisons of the population and housing unit counts. It also provides area measurements and density. The 

user notes section documents geographic changes over the past decade. This series is similar to the 

Census 2000 PHC-3 series. 

In each series, there is one report for each state, the District of Columbia, and Puerto Rico, plus a United 

States summary report. Many tables in the United States summary reports include data for Puerto Rico. 

The CPH-3, Characteristics of American Indians and Alaska Natives by Tribe, report provides population 

and housing information for selected American Indian and Alaska Native tribes. This report is similar to the 

Census 2000 PHC-5 report. This is a single report covering the entire United States.

HOW TO FIND GEOGRAPHIC AREAS AND SUBJECT MATTER DATA

This report includes a table finding guide to assist the user in locating those statistical tables that contain 

the desired data. The table finding guide lists alphabetically, by geographic area, the subjects shown in 

this report. To determine which tables in this report show data for a particular topic, find the subject in the 

left-hand column of the table finding guide and then look across the columns using the headings at the top 

for the desired type of geographic area. Figure I-1 is an example of a table finding guide. 

The table finding guide does not include cross-classification of subject-matter items. Additional information to locate data within specific reports is provided in the headnote at the top of the table finding guide 

and in the footnotes at the bottom of the guide.

Table Finding Guide

SUBJECTS BY TYPE OF GEOGRAPHIC AREA AND TABLE NUMBER

The types of geographic areas covered in this report are shown on the side, and subjects are shown at the top. See CPH-2-A, Population and 

Housing Unit Counts, Selected Appendixes (<www.census.gov/prod/cen2010/cph-2-a.pdf>), for a description of area classifications (Appendix A) 

and for definitions and explanations of subject characteristics (Appendix B).

HOW TO USE THE STATISTICAL TABLES

Parts of a Statistical Table

The census data included in printed reports are arranged in tables. Each table includes four major parts: (1) 

heading, (2) boxhead, (3) stub, and (4) data field. A typical census report table is illustrated in Figure I-2.

The heading consists of the table number, title, and headnote. The table number indicates the position of 

the table within the report, while the title is a brief statement indicating the subjects and time reference 

of the data presented in the table. The headnote is enclosed in brackets and is located under the title. It 

contains statements that qualify, explain, or provide information pertaining to the entire table. 
How to Use This Census Report I-3

U.S. Census Bureau, 2010 Census

The boxhead is under the heading. This portion of the table, which contains the individual column heads 

or captions, describes the data in each vertical column. In the boxhead of many tables, a spanner appears 

across and above two or more column heads or across two or more lower spanners. The purpose of a 

spanner is to classify or qualify items below it or separate the table into identifiable blocks in terms of 

major aspects of the data. 

The stub is located at the left edge of the table. It includes a listing of line or row captions or descriptions. 

At the top of the stub is the stubhead. The stubhead is considered to be an extension of the table title and 

usually shows generic geographic area designations and restrictions.

I-4 How to Use This Census Report

U.S. Census Bureau, 2010 Census

In the stub, several features are used to help the user better understand the contents of the table. Usually, 

a block of data lines is preceded by a sidehead. The sidehead, similar to a spanner, describes and classifies 

the stub entries following it. The use of indentation in a stub indicates the relationship of one data line to 

another. Indented data lines represent subcategories that, in most instances, sum to a total. Occasionally 

in tables, it is desirable to show one or more single-line subcategories that do not sum to the total. 

The data field is that part of the statistical table that contains the data. It extends from the bottom of the 

boxhead to the bottom of the table and from the right of the stub to the right edge of the page. 

Both geographic and subject-matter terms appear in tables. It is important to read the definitions of the 

terms used in the tables because census terms often are defined in special ways that reflect the manner in 

which the questions were asked and the data were tabulated. Definitions of geographic terms are provided 

in Appendix A of CPH-2-A, Population and Housing Unit Counts, Selected Appendixes (<www.census.gov

/prod/cen2010/cph-2-a.pdf>). Census tables often include derived measures such as medians, means, percentages, and ratios. These and other subject-matter terms are defined in Appendix B of the same report. 

Symbols and Geographic Abbreviations

The following symbols are used in the tables and explanations of subjects covered in 2010 Census reports:

• A dash ‘‘–’’ represents zero or a derived measure that rounds to less than 0.1. 

• (X) means not applicable. In the 1990 and earlier decennial census reports, three dots ‘‘. . . ’’ meant not 

applicable. 

• (NA) means not available. 

• The superscript prefix ‘‘r’’ indicates that a Census 2000 count has been revised since the publication 

of the Census 2000 reports as a result of certified Count Question Resolution (CQR) changes (see also 

<www.census.gov/prod/cen2000/notes/errata.pdf>). This symbol appears only in the 2010 Census 

CPH-2, Population and Housing Unit Counts, report series. 

• A minus sign ‘‘–’’ preceding a figure denotes decrease. The minus sign appears only in the 2010 Census 

CPH-2, Population and Housing Unit Counts, report series. 

The following are examples of geographic abbreviations and terms that may be used in the tables in this 

report:

• A ‘‘(part)’’ next to the name of a geographic area in a hierarchical presentation indicates that the geographic entity is located only partially in the superior geographic entity. For example, a ‘‘(part)’’ next to a 

place name in a county subdivision-place hierarchy indicates that the place is located in more than one 

county subdivision. (Places also may be ‘‘split’’ by county, congressional district, urban/rural, metropolitan area, voting district, and other geographic boundaries, depending on the presentation.) Other geographic entities also can be ‘‘split’’ by a higher-level entity. The exception is a tabulation block, which is 

unique within all geographic entities in census products. 

• ANVSA is Alaska Native village statistical area. 

• ANRC is Alaska Native Regional Corporation. 

• CCD is census county division. 

• CDP is census designated place. 

• CSA is combined statistical area. 

• NECTA is New England city and town area. 

• Metro Area is metropolitan statistical area.

GENERAL NOTES

User Note 1

The user should be aware that there are limitations to many of these data. Please refer to the text provided 

with this report for further explanation of the limitations of the data. The population and other data shown 

for the 2010 Census in this report are as of April 1, 2010; the boundaries used for all geographic entities 

are as of January 1, 2010. All boundaries are intended for Census Bureau statistical data collection and 

presentation only; their depiction and designation for statistical purposes do not constitute a determination of jurisdictional authority or entitlement. Corrections to the 2010 Census data as a result of certified 

Count Question Resolution (CQR) changes are available from the Census Bureau’s Internet site at 

<www.census.gov/prod/cen2010/notes/errata.pdf>.

User Note 2

Data comparability for county subdivisions is shown only when the county subdivision contains substantially the same territory as reported for Census 2000 (generally defined as at least 60 percent of the 

previous territory). There is no comparability provided for county subdivisions that have been extensively 

revised. Revised entities are noted by and within county. Changes to a geographic entity can be the result 

of legal change actions, statistical redefinition, correction of previous boundary or drafting errors, or new 

erroneous information.

Incorporated place and census designated place (CDP) comparability is provided for all places that retained 

their name or general area without regard to the amount of territorial change between censuses. Place 

comparability is not shown if the entity is new for the 2010 Census or is the result of a merger that created 

an entirely new entity, or if a 2010 Census geographic area shares no area with a Census 2000 area of the 

same name. American Indian area (including tribal subdivisions), Alaska Native area, and Hawaiian home 

land comparability follows the same rules as for place comparability.

User Note 3

When applicable, tables show the revised Census 2000 population and/or housing unit counts that 

resulted from the Count Question Resolution (CQR) program. These revised counts are accompanied by a 

prefix “r” symbol in the data tables.

Derived values (e.g., percent distribution, density, or change) that are calculated from Census 2000 population or housing unit counts only account for the aforementioned CQR revisions in certain cases. 

• Calculations include the corrected Census 2000 counts when a table:

o Shows population or housing unit change (or percent change) from 2000 to 2010.

o Shows population or housing unit change (or percent change) from 1990 to 2000, and also shows 

the 2000 population or housing unit count that it is derived from.

o Shows population or housing unit density or percent distribution in 2000, and also shows the 2000 

population or housing unit count that it is derived from.
III-2 User Notes

U.S. Census Bureau, 2010 Census

• Calculations do not include the corrected Census 2000 counts when a table:

o Shows population or housing unit change (or percent change) from 1990 to 2000, but does not 

show the 2000 population or housing unit count that it is derived from.

o Shows population or housing unit density or percent distribution in 2000, but does not show the 

2000 population or housing unit count that it is derived from. 

• When a table shows component parts of a revised 2000 population or housing unit count (e.g., classified by urban/rural or by size of place), the component parts may not sum to the total population 

or housing unit count, because the component parts were not revised during the 2000 CQR program. 

Therefore, any derived values (e.g., percent distribution or number of places by population size) for the 

component parts cannot account for the revised Census 2000 counts either.

HISTORICAL NOTES

The area of Delaware was part of the original territory of the United States. Included in the grant to 

William Penn, the Three Lower Counties (Delaware) were annexed as part of the grant establishing the 

Province of Pennsylvania in 1683. The counties were granted a separate charter providing semiautonomy 

in 1701, with generally the same boundary as the present state. In 1776, Delaware declared itself a 

separate government. Delaware ratified the U.S. Constitution on December 7, 1787; it was the first of the 

original 13 states to join the Union.

GEOGRAPHIC NOTES

Delaware is divided into three counties. The 27 county subdivisions in the state are census county divisions (CCDs), which are statistical subdivisions delineated for presentation of decennial census data. There 

are 57 incorporated places and 19 CDPs in Delaware. Incorporated places in the state are legally described 

as cities, towns, and villages. The Census Bureau treats all incorporated places and CDPs as dependent 

within CCDs.

GEOGRAPHIC CHANGE NOTES

The Geographic Change Notes listed below document high-level geographic entities—American Indian 

areas, Alaska Native areas, and Hawaiian home lands; counties and their equivalents; county subdivisions; and places—that are different from the information reported in Census 2000. The notes identify 

geographic entities whose name, legal description, and/or boundary have changed, entities that no longer 

exist, newly established entities (both legal and statistical), and changes in geographic relationships, such 

as places that exist in one county and have expanded into or withdrawn from another county (the notes 

do not identify the other county(ies) in which the entity exists; this can be determined from Table 9 of 

this publication), places that have been removed from comparable 2000 county subdivisions, and places 

that have become independent of or dependent within one or more county subdivisions. The changes are 

reported by and within county; counties without changes are not shown in the listing. Changes to American Indian areas, Alaska Native areas, and Hawaiian home lands appear after the list of counties; areas 

with no changes are not shown. A few of the reported changes in name, legal status, or legal relationship 

may be incorrect; if so, the correct version is shown in any Correction Notes section above. Some changes 

are the result of legal actions that took place prior to Census 2000 but were not reported in that census.

For the 2010 Census, the notes reflect any boundary change that affects a geographic entity, regardless 

of whether it is the result of legal action, redefinition of a statistical entity, correction of a previous drafting error, or new erroneous information. Between Census 2000 and the 2010 Census, the Census Bureau 

invested in improving the coordinate accuracy of its geographic database. As a result, the geographic 

positions of boundaries may be different between the two censuses even though little or no change actually occurred to the boundaries. In compiling the Geographic Change Notes, the Census Bureau inspected 

the many corrections to determine if a change actually affected significant land area or population. For 

example, the county-level text ‘‘all MCDs [minor civil divisions] revised’’ may reflect a legal redistricting 
User Notes III-3

U.S. Census Bureau, 2010 Census

of all county subdivisions in the county, a major or minor relocation of county subdivision boundaries due 

to more accurate mapping or more accurate boundary information, or a combination of these that, in one 

way or another, affect every county subdivision in a county. Boundary corrections that resulted in incorporated places gaining or losing territory are shown as annexations or detachments even if no legal action 

occurred between 2000 and 2010. Most places shown with a detachment resulted from such corrections. 

In states whose legal entities rarely undergo a legal boundary change, such as the New England states, 

most of the entities reported to have annexed, detached, exchanged, gained, or lost territory did so as the 

result of mapping changes, not legal actions. The extent and location of the boundary changes affecting 

any particular entity can be determined by comparing the TIGER/Line® Shapefiles, Cartographic Boundary 

Files, or a comparable set of maps for the 2000 and 2010 censuses.

Note: All legal and statistical area boundaries and names are as of January 1, 2010. Where international, state, county, independent city, and/or county subdivision boundaries

coincide, the map shows the boundary symbol for the highest level of these geographic entities. The county and independent city boundaries are always shown. Where a county

subdivision boundary symbol coincides with a place boundary, the map does not show the place boundary symbol. Where American Indian Reservation (Federal), American Indian

Reservation (State), State Designated Tribal Statistical Area, and/or Tribal Designated Statistical Area boundaries coincide with a county subdivision boundary, the map does not

show the county subdivision boundary symbol. Any geographic entity name may include ’(pt)’ if some portion of the entity extends beyond the limits of the map area displayed on

the page, or if multiple discontiguous pieces of the entity have been discretely labeled on the page. A geographic entity name may include ’(pts)’ if many discontiguous pieces

exist for that entity that cannot be discretely labeled. The boundaries shown on this map are for Census Bureau statistical data collection and tabulation purposes only; their

depiction and designation for statistical purposes does not constitute a determination of jurisdictional authority or rights of ownership or entitlement.
