United States Population and Housing Census 1980 - IPUMS

Censuses provide population numbers, household or family size and composition, and information on sex and age distribution. They often include other demographic, economic and health-related topics as well. The 1980 United States de jure census collected data by self-enumeration. A short form questionnaire was mailed to all households and a long form questionnaire was sent to half of housing units in places with a population under 2,500 and one-sixth of units in other areas. Subjects covered by the census include housing, household demographics, employment, education, migration, and fertility. The census day was April 1, 1980. A 5% sample of households that completed the long form questionnaire (11,343,120 individuals) is available through IPUMS International at the University of Minnesota. Dwellings are not identified in the microdata. The IPUMS sample for this census is notable because the variables have been harmonized with census data from other countries, allowing the data to be used together.
