Summary level and other technical concepts pertaining to summary files are briefly described in our guide, Census Summary Files: Technical Issues.

  • Public Law (P.L.) 94-171
    Also called the Redistricting file, it was the first file published from the 1980 Census and was used for congressional reapportionment. Data is based on the short form and focuses on age, sex, race, and Hispanic origin.
  • Public Use Microdata
    Public Use Microdata are records drawn from the responses to the long-form questionnaire. There are two files: one a sample of 1% of households and the other a 5% sample. For general description of microdata refer to Census Microdata Overview. Although it references 2000 Census, the concepts, though not the links to sources, are the same. The sources for all 1980 data are listed on this page. The 1980 samples are split in to the following groupings:
    • A Sample
      5% or 1% with states, counties, groups of counties, and large cities
    • B Sample
      1% only with some states, SMSAs, selected counties, and selected places
    • C Sample
      1% only with divisions, some States, selected places of 100,000 or more population, selected urban areas, and an urban/rural breakdown
    • D Sample
      1% only using a unique geography that groups counties based on the labor market
  • Maps and Spatial Data
    • Spatial Data
      Spatial Files were developed for 1980 boundaries sometime after the release of the 1980 Census.
    • Maps
      Columbia's holdings for 1980 maps are described on the Government Documents 1980 Decennial Census Information web page.
