|Title:||Census of Population and Housing, 1980 [United States]: Summary Tape File 1C|
|Primary Investigator(s):||United States Department of Commerce. Bureau of the Census|
|Abstract:||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. The series is comprised of STF 1A, STF 1B, STF 1C, and STF 1D. STF 1A, STF 1B, and STF 1D have 52 separate files, one for each state, Puerto Rico, and the District of Columbia. 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 all 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 1C contains summaries for the United States as a whole, regions, divisions, state or state equivalents, standard consolidated statistical areas (SCSAs), standard metropolitan statistical areas (SMSAs), urbanized areas, county or county equivalents, places of 10,000 or more people, minor civil divisions of 10,000 or more, and congressional districts. The number of data records in each file varies by state.|
