Census IPUMS Research

Integrated Public Use Microdata Series (IPUMS) is the world's largest individual-level population database. IPUMS consists of microdata samples from United States and international census records, as well as data from U.S. and international surveys. IPUMS data includes name, age, gender, place of birth, income, race or ethnicity, marital status, education, and employment. This is a Census copy of the IPUMS data for use in the FSRDC.
