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-1-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.

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.

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 

SUBJECTS BY TYPE OF GEOGRAPHIC AREA AND TABLE NUMBER

Subjects covered in this guide are shown on the left side, and types of geographic areas are shown 

at the top. Table numbers shown in bold indicate that either all or part of the table is presented for 

the American Indian and Alaska Native population in American Indian and Alaska Native areas, or 

for the Native Hawaiian and Other Pacific Islander population in Hawaiian home lands. See CPH-1-A, 

Summary Population and Housing Characteristics, Selected Appendixes (<www.census.gov/prod 

/cen2010/cph-1-a.pdf>) for a description of area classifications (Appendix A) and for definitions 

and explanations of subject characteristics (Appendix B).

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-1-A, Summary Population and Housing Characteristics, Selected Appendixes 

at <www.census.gov/prod/cen2010/cph-1-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.

I-4 How to Use This Census Report

U.S. Census Bureau, 2010 Census

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. This symbol appears 

only in the 2010 Census CPH-2, Population and Housing Unit Counts, report series.

•	 (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.

•	 Micro Area is micropolitan statistical area.

•	 OTSA is Oklahoma tribal statistical area.

•	 SDTSA is state designated tribal statistical area.

•	 TDSA is tribal designated statistical area.

•	 UT is unorganized territory.

GRAPHICS

USER NOTES

User notes include corrections, errata, and related explanatory information. They also provide information 

about unique characteristics of the report and changes or corrections made too late to be reflected in 

the text or tables themselves. However, sometimes this information becomes available too late to be 

reflected even in the user notes. Therefore, updates are available in the Notes and Errata document at 

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

 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.
