IPUMS

These projects from the Minnesota Population Center facilitate comparative over-time and cross-country analyses by bringing a consistent format and documentation to U.S. and international microdata, including censuses and health surveys. All IPUMS data are free; users simply need to register for access. Global data projects include IPUMS-International (national censuses), IPUMS-DHS (Demographic and Health Surveys), and IPUMS-PMA (Performance Monitoring and Accountability survey data from ten Family-Planning-2020 pledging countries). They have other data sets as well.
