INTRODUCTION

Data from Census 2000 are presented in three printed report series:

1. PHC-1, Summary Population and Housing Characteristics

2. PHC-2, Summary Social, Economic, and Housing Characteristics

3. PHC-3, Population and Housing Unit Counts

The data from Census 2000 were derived from a limited number of basic questions asked of the

entire population and about every housing unit (referred to as the 100-percent questions, found

on the ‘‘short form’’), and from additional questions asked of a sample of the population and

housing units (referred to as the sample questions, found on the ‘‘long form’’).

The PHC-1, Summary Population and Housing Characteristics, report series provides data based

on the 100-percent questions. The subjects are 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 1990 census

CPH-1 series.

The PHC-2, Summary Social, Economic, and Housing Characteristics, report series provides

sample data based on both the 100-percent and the sample questions. Sample subjects include

place of birth; residence in 1995; language; educational attainment and school enrollment; veteran status; disability status; employment status; journey to work; work status, earnings, income,

and poverty status in 1999; physical housing characteristics; units in structure; fuel and equipment characteristics; owner and renter household characteristics, such as year owner moved into

unit; home value; contract and gross rent; and mortgage and rental cost characteristics. This

series is similar to the 1990 census CPH-5 series.

The PHC-3, Population and Housing Unit Counts, report series provides Census 2000 and historical comparisons of the 100-percent population and housing unit counts. It provides land and

water area measurements, and population density. The user notes section documents geographic

changes over the past decade. This series is similar to the 1990 census CPH-2 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.

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 lefthand 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 crossclassifications of subjectmatter 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.

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.

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.

Figure I–1.

I–2 How to Use This Census Report

U.S. Census Bureau, Census 2000
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.

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 PHC-3-A, Population and Housing Unit Counts, Selected Appendixes,

Appendix A. 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 Census

2000 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.

Figure I–2.

How to Use This Census Report I–3

U.S. Census Bureau, Census 2000
• The superscript prefix ‘‘r’’ indicates that the count has been revised since the publication of the

1990 census reports, or that the area was erroneously omitted or not shown in the correct geographic relationship in the 1990 census reports. This symbol appears only in the Census 2000

PHC-3, Population and Housing Unit Counts, report series.

• A dagger ‘‘†’’ next to the name of a geographic area indicates that there has been a geographic

change (for example, an annexation or detachment, a new incorporation, or a name change)

since the information was published for the 1990 census for that area. This symbol appears

only in the Census 2000 PHC-3, Population and Housing Unit Counts, report series. The geographic change information for the entities in a state is shown in the ‘‘User Notes’’ section of the

Census 2000 PHC-3 report for that state.

• A plus sign ‘‘+’’ is appended to the lower bound of the highest interval when the median falls in

the upper interval of an open-ended distribution. A minus sign ‘‘-’’ is appended to the upper

bound of the lowest interval when the median falls in the lowest interval of an open-ended

distribution. For more information on medians, see the section on ‘‘Derived Measures’’ in

Appendix B.

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

Census 2000 PHC-3, Population and Housing Unit Counts, report series.

• (U) means the place or place part is composed entirely of urban land area. The (U) appears only

in the Census 2000 PHC-3, Population and Housing Unit Counts, report series.

• (R) means the place or place part is composed entirely of rural land area. The (R) appears only in

the Census 2000 PHC-3, Population and Housing Unit Counts, report series.

• (U/R) means the place or place part is composed of both urban land area and rural land area.

The (U/R) appears only in the Census 2000 PHC-3, Population and Housing Unit Counts, report

series.

The following geographic abbreviations and terms 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.

• CMSA is consolidated metropolitan statistical area.

• MA is metropolitan area.

• MSA is metropolitan statistical area.

• OTSA is Oklahoma tribal statistical area.

• PMSA is primary metropolitan statistical area.

• SDAISA is state designated American Indian statistical area.

• TDSA is tribal designated statistical area.

• UT is unorganized territory.

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 Census 2000 in this report is as of April 1, 2000; the boundaries used for all

geographic entities are as of January 1, 2000. 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 Census 2000 data as a result of certified Count Question Review changes are available from

the Census Bureau’s Internet site at: www.census.gov/prod/cen2000/notes/errata.pdf.

HISTORICAL NOTES

The area of the District of Columbia was part of the original territory of the United States. The District of Columbia was formed from territory ceded by Maryland and Virginia in 1788, and was

established in accordance with Acts of Congress passed in 1790 and 1791. Its boundary, a square

ten miles on a side with vertices at the cardinal points to resemble a diamond, was established on

March 30, 1791, and included all of the territory within present-day Arlington County, Virginia,

and part of Alexandria city, Virginia. The portion south of the Potomac River was retroceded to Virginia in 1846.

Census data for the District of Columbia are available beginning with the 1800 census. The population shown for the District of Columbia from 1800 to 1840 does not include the portion of Virginia legally included in the district at the time of those censuses. The population of the District of

Columbia as legally existent in those censuses is: 43,712 in 1840; 39,834 in 1830; 33,039 in

1820; 24,023 in 1810; and 14,093 in 1800. Congress abolished the original county (Washington

County) and incorporated places (Georgetown and Washington cities) in the District of Columbia in

1871, but later reestablished the city of Washington. The Census Bureau continued to recognize

the boundaries of the previously existing areas for the 1880 and 1890 censuses. Congress has

treated the District of Columbia as coextensive with Washington city since 1895.

GEOGRAPHIC NOTES

The Census Bureau treats the District of Columbia as equivalent to a state for data presentation

purposes. Because the District of Columbia is not subdivided into any county or county subdivision entities, the Census Bureau treats the entire District of Columbia as statistically equivalent to

a county and Washington city as statistically equivalent to a county subdivision. It treats Washington city as a legally incorporated place geographically coextensive with the District of Columbia.

1 The District of Columbia is statistically equivalent to a state and also treated as statistically

 equivalent to a county. Washington city is not divided into any subdivisions and thus serves as

 the statistical equivalent of a legal county subdivision. The boundaries and name for the county

 subdivision are the same as the city and not shown on the map.

Note: All legal boundaries and names are as of January 1, 2000. Where state, county, and/or county

subdivision boundaries coincide, the map shows the boundary symbol for the highest level of these geographic

entities. The county boundary is always shown. Where a county subdivision boundary coincides with a place

boundary, the map does not show the place 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.

Metropolitan area boundaries are those defined by the Federal Office of Management and Budget on June 30, 1999.

The use of ’(PART)’ indicates that the geography is either discontiguous, extends beyond the map page, or in the

case of central cities, the central city extends beyond the MSA/CMSA boundary. All other boundaries and names

are as of January 1, 2000.
