IPUMS Archive


Welcome to the archival versions of the Integrated Public Use Microdata Series (IPUMS) at ICPSR. This page provides links to older versions of the IPUMS website.  Each archived version of the site includes data, documentation, a functioning extract system, and all data extract requests made up to that point.

These sites are intended for users who want to replicate their own or others' research results using the same versions of the datasets and documentation that were available when the research was originally conducted.

Please do not use these sites for ongoing research. The data or documentation may have changed.
