With 610 million records, spanning over 100 countries, IPUMS International is the world's largest collection of publicly available individual-level census data. The data are anonymized samples from population censuses taken from around the world since 1960. Most census data samples contain basic demographic information, along with additional information on religion, occupation, industry, income, work status, education, type of housing, disability status, and household characteristics. In addition, supplemental information is available for some countries that includes fertility data, migration data, mortality data, and GIS boundary files. IPUMS International research topics include: the impact of internal displacement on receiving communities, migration and social inequality in Europe, the link between climate change and reproductive health, and the relationship between single motherhood and educational outcomes for children in Vietnam.
