Version V2

This data collection contains summary statistics on population and housing subjects derived from the responses to the 2010 Census questionnaire. 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). The summary statistics are presented in 331 tables, which are tabulated for multiple levels of observation (called "summary levels" in the Census Bureau's nomenclature), including, but not limited to, regions, divisions, states, metropolitan statistical areas, micropolitan statistical areas, counties, county subdivisions, places, congressional districts, American Indian and Alaska Native area and Hawaiian home lands, ZIP Code tabulation areas, census tracts, block groups, and blocks. There are 177 population tables and 58 housing tables shown down to the block level; 82 population tables and 4 housing tables shown down to the census tract level; and 10 population tables shown down to the county level. Some of the summary areas are iterated for "geographic components" or portions of geographic areas, e.g., the principal city of a metropolitan statistical area. With one variable per table cell and additional variables with geographic information, the collection comprises 2,544 data files, 48 per state, the District of Columbia, Puerto Rico, and the National File.

The Census Bureau released SF1 in three stages: initial release, National Update, and Urban/Rural Update. The National Update added summary levels for the United States, regions, divisions, and geographic areas that cross state lines such as Combined Statistical Areas. The Urban/Rural Update added urban and rural population and housing unit counts, summary levels for urban areas and the urban/rural components of census tracts and block groups, geographic components involving urbanized areas and urban clusters, and two new tables (household type by relationship for the population 65 years and over and a new tabulation of the total population by race). This data collection comprises the intial release and National Update. The Urban/Rural update is available as ICPSR 34746.

SF1 is supplied in 54 ZIP archives. There is an archive for each state, the District of Columbia, Puerto Rico, and the National File. The last archive contains a Microsoft Access database shell and additional documentation files besides the codebook.

2013-07-15 ICPSR changed the study title: "With National Update" was added to the title. In addition, the codebook was replaced with the latest version issued by the Census Bureau on September 2012. The codebook is now available as a separate file and is no longer included in the last ZIP archive.
