Census 2000 Summary File 1 [name of state¹ or United States]/prepared by the U.S. Census Bureau, 2001.


¹This includes the District of Columbia and Puerto Rico.

Summary statistics.

Summary File 1 (SF 1) contains the 100-percent data, which is the information compiled from the questions asked of all people and about every housing unit. Population items include sex, age, race, Hispanic or Latino, household relationship, and group quarters. Housing items include occupancy status, vacancy status, and tenure (owner occupied or renter occupied).

There is a total of 171 population tables (identified with a "P") and 56 housing tables (identified with an "H" shown down to the block level, and 59 population tables shown down to the census tract level (identified with a "PCT") for a total of 286 tables. There are 14 population tables and 4 housing tables shown down to the block level, and 4 population tables shown down to the census tract level that are repeated by major race and Hispanic or Latino groups².

SF 1 includes population and housing characteristics for the total population, population totals for an extensive list of race (American Indian and Alaska Native tribes, Asian, and Native Hawaiian and Other Pacific Islander) and Hispanic or Latino groups, and population and housing characteristics for a limited list of race and Hispanic or Latino groups. Population and housing items may be cross tabulated. Selected aggregates and medians also are provided. A complete listing of subjects in this file is found in the section, "Subject Locator."





²These selected tables are repeated by the following: 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. One matrix, PCT12, is also repeated by Black or African American alone, not Hispanic or Latino; American Indian and Alaska Native alone, not Hispanic or Latino; Asian alone, not Hispanic or Latino; Native Hawaiian and Other Pacific Islander alone, not Hispanic or Latino; Some other race alone, not Hispanic or Latino; and Two or more races, not Hispanic or Latino.

Summary File 1 (SF 1) 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. Because urban and rural areas will not be available until 2002 as part of the final national file, an advance national file will be released in late 2001 that provide all SF 1 data without the urban and rural components.

This abstract lists the most frequently accessed geographic levels. The "Summary Level Sequence Chart" section outlines the hierarchical and inventory geographic summaries in their entirety. Three summary level sequence charts are provided: for the state files, for the advance national file, and for the final national file.

The section on User Updates informs data users about corrections, errata, and related explanatory information. These updates provide information about unique characteristics, changes, or corrections. However, sometimes this information becomes available too late to be reflected in the tables (matrices) or related documentation. User updates are available on the Census Bureau's Internet site at www.census.gov. Users also can register to receive user updates by e-mail by contacting Customer Services Center, Marketing Services Office, U.S. Census Bureau on 301-763-INFO (4636) (webmaster@census.gov).
