U.S. Census Data for Social, Economic, and Health Research

IPUMS USA collects, preserves and harmonizes U.S. census microdata and provides easy access to this data with enhanced documentation. Data includes decennial censuses from 1790 to 2010 and American Community Surveys (ACS) from 2000 to the present. (Collection level DOI: 10.18128/C010)

IPUMS USA includes basic demographic data (e.g., age, race, sex, marital status, and relationship to the head of household), along with economic data (e.g., occupation, industry, income, work status, education, migration, place of work, type of housing, disability / veteran status, household appliances, and housing characteristics). Recent work using IPUMS USA has looked at sex-based income differentials, housing security based on geographic location, family formation patterns, employment outcomes for women and migrants, and intergenerational economic mobility. For additional papers published using IPUMS USA data, see the IPUMS bibliography.
