Abstract: 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. Each file provides different geographic coverage. STF3C is a National-level file containing summaries for the following levels: United States, census regions, census divisions, States, standard consolidated statistical areas (SCSAs), SMSAs, urbanized areas (UAs), counties, places of 10,000 or more, MCDs of 10,000 or more in eleven selected states, and Congressional districts. Each file has a logical record length of 12,096 characters with six physical record segments of 2,016 characters each. The number of data records in each file varies by state. NOTE TO USERS: ICPSR has all of the revised data for STF3A and STF3C files from the Census Bureau. In the event of any further corrections by the Census Bureau, ICPSR will announce the availability of corrected files in the ICPSR Bulletin. The Census Bureau's machine-readable data dictionary for STF3 is also available on the same tape as CENSPAC 3.2 (ICPSR #7789), the software package designed specifically by the Census Bureau for use with the 1980 Census data files. A description of CENSPAC is located in the Instructional Packages section of the Guide.
