Census 2010 Summary File 1 [name of state¹ or United States]/prepared by the U.S. Census Bureau, 2011.



¹This includes the District of Columbia and Puerto Rico.

Summary statistics.

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

There are 177 population tables (identified with a " P" ) and 58 housing tables (identified with an " H" ) shown down to the block level; 82 population tables (identified with a " PCT" ) and 4 housing tables (identified with an HCT) shown down to the census tract level; and 10 population tables (identified with a PCO) shown down to the county level, for a total of 331 tables. There are 14 population tables and 4 housing tables shown down to the block level and 5 population tables shown down to the census tract level that are repeated by the major race and Hispanic or Latino groups.².

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 Subject Locator chapter.



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 2012 as part of the urban/rural update file, a national update file will be released in late 2011 that provides all SF 1 data without the urban and rural components.

User updates inform data users about corrections, errata, and related explanatory information. However, sometimes this information becomes available too late to be reflected in the product or related documentation. User updates are available on the U.S. Census Bureaus Internet site at www.census.gov

2010 Census Summary File 2 (SF 2). Files containing cross-tabulations of information on age, sex, household relationship, household type, household size, family type, family size, group quarters population, occupancy status, tenure, etc., for many race and Hispanic or Latino groups and American Indian and Alaska Native tribes. The file for each state includes data down to the census tract level, if there are 100 or more people of the specified population group in a given geographic area. Other tabulations are available only down to the county level (planned release: December 2011-April 2012). SF 2 will be updated with national-level data (planned release: May 2012) and urban/rural data (planned release: January 2013). Files and reference maps will be made available through American FactFinder.
