Version V1

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 1A provides summaries for state or state equivalent, county or county equivalent, minor civil division/census county division (MCD/CCD), place or place segment within MCD/CCD or remainder of MCD/CCD, census tract or block numbering area (BNA) or untracted segment within place, place segment or remainder or MCD/CCD, and block group (BG) or BG segment or enumeration district (ED). This file contains 57 data files, one for each state, the District of Columbia, Puerto Rico, and the United States possessions, which include American Samoa, Guam, Northern Mariana Islands, the Trust Territory of the Pacific Islands, and the Virgin Islands. The information on the United States possessions is similar but not identical to the other data and is documented in a separate codebook. Puerto Rico is also documented by a separate codebook.
