IPUMS is a service of the Minnesota Population Center that provides integrated census and survey data from around the world. IPUMS maintains nine different data products including IPUMS USA and IPUMS CPS, widely used in social science research. Researchers typically create custom extracts using the IPUMS webiste or API (beta), but the extracts are subject to licenses that restrict or prohibit redistribution. Additionally, the underlying data products are subject to change over time, so there is no guarantee that a future replicator will obtain the same extract using the original author’s query.
IPUMS USA: Full Count data may not be redistributed. Sample data may be published to meet journal requirements.
IPUMS CPS: Subsets of data may be published to meet journal requirements.
IPUMS International: Redistribution is prohibited.
