IPUMS-International currently disseminates census microdata from 82 countries around the world. It’s an impressive collection. But it still only covers about half the world’s countries. Under the TerraPop project, we are working to assemble a truly comprehensive global collection of population data.
The team at IPUMS-USA is excited to announce the release of the 2015 American Community Survey (ACS) microdata file. IPUMS USA now contains 16 years of yearly ACS microdata for analysis. For researchers, ACS data is the most frequently used IPUMS data.
IPUMS CPS has added a new variable to unlock longitudinal information in CPS data called CPSIDP. The identifier, the result of a major initiative from the Minnesota Population Center, uniquely identifies individuals who are in the CPS and is assigned to the individual in each of the (up to) eight times over sixteen months that the individual is in the survey.
