Summary File 1 (SF1) contains summary statistics on population and housing subjects derived from questions on 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. 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, and Puerto Rico, plus 48 for the National File which contains summary levels not included in the state files (e.g. regions and divisions).
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 the codebook, other documentation files, and a Microsoft Access database shell.
