Integrated Public Use Microdata Series (IPUMS) 1850 - 1990

This data collection contains information relating to the historical censuses of the United States that make up the Integrated Public Use Microdata Series (IPUMS) disseminated through the Minnesota Population Center at the University of Minnesota. Drawn from original census enumeration forms, the data collections in this series include samples of the American population taken from the censuses of 1850 to 1990 (excluding 1890 and 1930). Data files comprise both individual and household records and include information on a broad range of population characteristics, including fertility, nuptiality, life-course transitions, immigration, internal migration, labor-force participation, occupational structure, education, ethnicity, and household composition. Also available is IPUMS-International, a preliminary database describing 48 million persons in six countries: Colombia, France, Kenya, Mexico, United States, and Vietnam. Information about the IPUMS-International samples and variables, and other supporting documentation, are available on the IPUMS website, but researchers must apply for access to the data.
