Census of population and housing, 1980 [United States]

Description

Summary Tape File 3 consists of four sets of computer-readable data file containing detailed tabulations of the nation's population and housing characteristics produced from the 1980 census. The files contain sample data inflated to represent the total United States population. The files also contain 100% counts and unweighted sample counts of persons and housing units. This series is comprised of STF3A, STF3B, STF3C, and STF3D. All four files have identical tables and format except for the omission of 100% counts for population and housing in STF3B. STF3A, STF3B, AND STF3D have 51 separate files, one for each state, and the District of Columbia. STF3C consists of one nation-wide datafile containing information about all states. All files in the STF3 series are identical, containing 321 substantive data variables organized in the form of 150 ''tables,'' as well as standard geographic identification variables. Population items tabulated for each person include demographic data and information on schooling, ethnicity, labor force status, children, and details about occupation and income. Housing items include data on size and condition of the housing unit as well as information on value, age, water, sewage and heating, vehicles, and monthly owner costs.
