Chapter Contents
The decennial census yields a wealth of data, which have virtually unlimited applications. A comprehensive data program offers census information on the Internet, in electronic media (CDROM/ DVD), and in print. A complete list of Census 2000 data products, with their release status, is available at http://www.census.gov/population/www/censusdata/c2kproducts.html.
Detailed results of Census 2000 are contained in a series of five files called summary files. These can be accessed through the Internet and on CD-ROM or DVD. In addition, three series of reports derived from these files are available in print and in Portable Document Format (PDF) on the Internet.

Census 2000 data are available at several locations on the Census Buraus Web site. The Census 2000 Gateway page provides links to Census 2000 data, information, and reference materials. It is accessed from the Census Bureau's home page (www.census.gov) or at http://www.itl.nist.gov/fipspubs/index.htm. Links from the Gateway page include American FactFinder®; State and County QuickFacts; other prepared Census 2000 tables, including rankings and comparisons; reference materials; user updates; and Census in the Schools.
American Factfinder (factfinder.census.gov) is the most comprehensive source of Census 2000 data, providing all summary file tables for all levels of census geography. Quick tables (single geography tables) and geographic comparison tables (data for more than one geographic area) are also available on American FactFinder
Most Census 2000 tabulations are also available on CD-ROM and/or DVD. Viewing software is included on the DVDs and most CDs. These may be ordered by phone through the Census Bureau's Customer Services Center on 301-763-4636, or via e-commerce by selecting Catalog from the Census Bureau's home page. For more information on the products and ordering options, access the Census Catalogs product order form at https://catalog.mso.census.gov.

The first Census 2000 data files released are the information required for local redistricting. The data include tabulations of 63 race categories, cross-tabulated by Hispanic or Latino and not Hispanic or Latino for the total population and the population 18 years old and over. These tabulations are presented for areas as small as blocks, census tracts, and voting districts. They are available through the Internet (American FactFinder) and as a CD-ROM series (state files). In American FactFinder (factfinder.census.gov), all redistricting data tables are available by selecting Data Sets on the FactFinder main page. FactFinder also has one quick table and one geographic comparison table based on this file.
This file presents counts and basic cross-tabulations of information collected from all people and housing units. This information includes age, sex, race, Hispanic or Latino origin, household relationship, and whether the residence is owned or rented. Data are available down to the block level for many tabulations, but only to the census-tract level for others. Summaries are included for other geographic areas, such as ZIP Code® Tabulation Areas(ZCTAs™) and Congressional Districts (106th Congress). There are individual state files and two national files in this series. The final national file provides the first available urban and rural data. The complete Summary File 1 is available on the Internet (American FactFinder) and on CD-ROM/DVD.
Additional tables derived from this summary file are also available on the Census Bureau's Internet site. These can be located through the Census 2000 Gateway page at http://www.census.gov/main/www/cen2000.html. Related products include a demographic profile that provides a snapshot of the geographic area, quick tables, geographic comparison tables, and two printed report series, Summary Population and Housing Characteristics (PHC-1) and Population and Housing Unit Counts (PHC-3).

This file presents data similar to the information included in Summary File 1, but the tables in this file are iterated for a selected list of race and Hispanic or Latino categories and for American Indian and Alaska Native tribes. These data are shown down to the census tract level for up to 250 race and ethnic categories that meet a specified minimum population size threshold of 100 in a geographic area. The complete SF 2 is available on the Internet (American FactFinder) and on CD-ROM/DVD. American FactFinder also offers various quick tables and geographic comparison tables derived from SF 2.
This file is the first release of the information collected on a sample basis. It includes data on income, educational attainment, poverty status, home value, and population totals for foreign born and ancestry groups. Data are provided down to the block group level for many tabulations but only down to the census tract for others. SF 3 also includes data by ZCTAs and Congressional Districts (106th Congress).
Data for each state and a national file are available on the American Factfinder and on CD-ROM/DVD. Related products include a three-page demographic profile available on the Internet, various quick tables and geographic comparison tables available through American Factfinder, and a printed report series, Summary Social, Economic, and Housing Characteristics (PHC-2).

This file includes tabulations of the population and housing data collected from a sample of the population. Just as in Summary File 2, the tables in SF 4 are iterated for a selected list of race and Hispanic or Latino origin groups and for American Indian and Alaska Native tribes. Tables are also iterated for 86 ancestry groups. SF 4 is available on the Internet (American FactFinder) and on CD-ROM/DVD. American FactFinder also offers various quick tables and geographic comparison tables derived from Summary File 4.
Microdata products allow users to prepare their own customized tabulations and cross tabulations of most population and housing subjects, using specially prepared microdata files. These files are the actual responses to census questionnaires, but with names or addresses removed and the geography sufficiently broad to protect confidentiality. Microdata are available on CD-ROM/DVD and may be available for query via the Internet.
There are two PUMS files: a 1-percent sample for developing tabulations for metropolitan areas and a 5-percent sample that provides tabulations for state and substate areas. Both files are available on CD-ROM/DVD.
Tabulations can be prepared online using the full database of individual responses, subject to restrictions and filters required to protect the confidentiality of individual responses. The Internet availability of this function is subject to policy decisions on access and confidentiality.
There are three series of printed reports with one report per state and a national summary volume. These reports are sold through the U.S. Government Printing Office. Much of the information in these series is available earlier in other data products. For release and ordering information, see the Census Catalog (a href="https://catalog.mso.census.gov/" target="_blank" class="doc_ExternalLink">https://catalog.mso.census.gov/).
Profiles and other data tables are generally available on the Internet. Printed copies of the profiles are offered as a print-on-demand product. Contact the Customer Services Center (301-763-4636) for pricing and availability.
