Geocorr 2022: Now With 2020 (and 2010) PUMAs

We’ve added several new geography types to the Geocorr 2022 application. The new 2020-vintage PUMAs (public use microsample area), released just a few weeks ago, are now available. By request, we’ve also restored the 2010-vintage PUMAs to facilitate crosswalks.

Because the new PUMAs are based on the 2020 census but were released in 2022, we’re interchangeably calling them 2020 and 2022 PUMAs. (This is the same way we handled the 2010/2012 PUMAs.)

For more information about PUMAs, please refer to our “All about PUMAs” page (now due for a revision!) or the Census Bureau’s PUMA reference.
