IPUMS

World's largest individual-level population database

IPUMS, which originally stood for Integrated Public Use Microdata Series but no longer abbreviates anything, is the world's largest individual-level population database. IPUMS consists of microdata samples from United States (IPUMS-USA) and international (IPUMS-International) census records, as well as data from U.S. and international surveys. The records are converted into a consistent format and made available to researchers through a web-based data dissemination and analysis system.
