Census of Population and Housing, 1980 [United States]: Summary Tape File 1D

Summary Tape File (STF) 1 consists of four sets of computer-readable data files containing detailed tabulations of the nation's population and housing characteristics produced from the 1980 Census. This series is comprised of STF 1A, STF 1B, STF 1C, and STF 1D. All files in the STF 1 series are identical, containing 321 substantive data variables organized in the form of 59 "tables," as well as standard geographic identification variables. All of the data items contained in the STF 1 files were tabulated from the "complete count" or "100-percent" questions included on the 1980 Census questionnaire. All four groups of files within the STF 1 series have identical record formats and technical characteristics and differ only in the types of geographical areas for which the summarized data items are presented. STF 1D provides summaries for state or state equivalent, congressional district (as constituted for the 98th Congress), county or county equivalent, places of 10,000 or more people, and minor civil divisions (MCD) or census county divisions (CCD). Housing items tabulated include occupancy/vacancy status, tenure, contract rent, value, condominium status, number of rooms, and plumbing facilities. Population items include demographic information such as age, sex, race, marital status, Spanish origin, household relationship, and household type. Selected aggregates, means, and medians are also provided. See the related collection, CENSUS OF POPULATION AND HOUSING, 1980 [UNITED STATES]: SUMMARY TAPE FILE 1H (ICPSR 8401).
