IPUMS Series

A project of the Minnesota Population Center (MPC), the IPUMS is divided into three series - IPUMS-USA, IPUMS-International, and IPUMS-CPS. Each data series is accessible through a user-friendly web interface where you can search for variables and then create and download customized datasets (download requires free registration). The IPUMS-USA contains harmonized data on people from the decennial census and American Community Survey from 1850 to present. IPUMS-International contains harmonized data from 1960 to present on over 279 million people in 130 censuses from around the world. The IPUMS-CPS contains harmonized data from the Current Population Survey March File from 1962 to the present.
