A profile includes four tables that provide various demographic, social, economic, and housing characteristics for the United States, states, counties, minor civil divisions in selected states, places, metropolitan areas, American Indian and Alaska Native areas, Hawaiian home lands and congressional districts (106th Congress). It includes 100-percent and sample data from Census 2000.
Summary File 1 (SF 1) contains 286 detailed tables focusing on age, sex, households, families, and housing units. These tables provide in-depth figures by race and Hispanic origin; some tables are repeated for each of nine race/Latino groups. Counts also are provided for over forty American Indian and Alaska Native tribes and for groups within race categories. The race categories include eighteen Asian groups and twelve Native Hawaiian and Other Pacific Islander groups. Counts of persons of Hispanic origin by country of origin (twenty-eight groups) are also shown.
Summary File 1 presents data for the United States, the 50 states, and the District of Columbia in a hierarchical sequence 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.
Geographic coverage for Puerto Rico is comparable to the 50 states. Data are presented in a hierarchical sequence down the block level for many tabulations, but only to the census tract level for others. Geographic areas include barrios, barrios-pueblo, subbarrios, places, census tracts, block groups, and blocks. Summaries also are included for other geographic areas such as ZIP Code Tabulation Areas (ZCTAs).
Summary File 1 detailed tables are identified according to geographic coverage:
Additional tables and maps have been derived from the detailed tables. For fast, easy access to all tables and maps in Summary File 1, go to the Data Sets page.
Summary File 2 (SF 2) contains 47 detailed tables focusing on age, sex, households, families, and occupied housing units for the total population. These tables are repeated for 249 detailed population groups based on the following criteria:
For a complete list of the 249 population groups, see Appendix H of the SF 2 Technical Documentation (PDF). Data from the 2000 census will be released over the next two years on a flow basis. These state-by-state news releases (including data for the District of Columbia and Puerto Rico) provide users these data on individual state web pages as they become available.
Summary File 3 consists of 813 detailed tables of Census 2000 social, economic and housing characteristics compiled from a sample of approximately 19 million housing units (about 1 in 6 households) that received the Census 2000 long-form questionnaire. Fifty-one tables are repeated for nine major race and Hispanic or Latino groups: 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.
Summary File 3 presents data for the United States, the 50 states, the District of Columbia and Puerto Rico in a hierarchical sequence down to the block group for many tabulations, but only to the census tract levels for others. Summaries are included for other geographic areas such as Zip Code Tabulation Areas (ZCTAsTM) and Congressional districts (106th Congress).
Summary File 3 includes 484 population tables and 329 housing tables that are identified according to geographic coverage:
Summary File 4 (SF4) contains the sample data, which is the information compiled from the questions asked of a sample of all people and housing units.
The sample data are presented in 213 population tables (matrices) and 110 housing tables, identified with "PCT" and "HCT", respectively. Each table is iterated for 336 population groups: the total population, 132 race groups, 78 American Indian and Alaska Native tribe categories (reflecting 39 individual tribes), 39 Hispanic or Latino groups, and 86 ancestry groups.
SF 4 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. Data are provided down to the census tract level.
The American Indian and Alaska Native Summary File (AIANSF) contains sample data, which is the information compiled from the questions asked of a sample of all people and housing units.
The sample data are presented in 213 population tables (matrices) and 110 housing tables, identified with "PCT" and "HCT," respectively. The tables are repeated or iterated for the total population, the total American Indian and Alaska Native population, the total American Indian population, the total Alaska Native population, and for 1,081 additional specified American Indian and Alaska Native tribes. For any of these iterations, tables will be shown only if the specific population threshold is met. The population for the specific iteration in a specific geographic area must be at least 100 people (based on a 100-percent count) of the specified population and include at least 50 unweighted sample cases. This threshold is based on respondents who reported only one tribe.
The AIANSF is released as one file providing data for the United States, regions, divisions, states (excluding Puerto Rico as a state equivalent), metropolitan areas, American Indian and Alaska Native areas, and Hawaiian home lands.
As a result of population changes between the 1990 and 2000 censuses, 8 states gained members and 10 states had fewer members in the House of Representatives. The regional patterns of change in congressional representation between 1990 and 2000 reflect the Nation’s continuing shift in population from the Northeast and Midwest to the South and West.
Based on the Census 2000 apportionment, each member of the U.S. House of Representatives represented an average population of 646,952.
