Census Tract to PUMA Relationship File for 2020 Boundaries

1

Hello everyone,

I am trying to find a relationship file that links each census tract to its corresponding PUMA for the 2020 boundaries. I was able to find this file for the 2010 boundaries, but I haven’t been able to find an updated version for 2020.

Does anyone know if such a file exists or where I might be able to find it?

Also, does anyone know whether the 2017–2021 5-Year ACS data uses 2020 or 2010 census tract boundaries?

Thank you !

IPUMS USA provides PUMA maps, boundary files & composition information through the Geographic Tools & Resources page. There’s a link there to the 2020 PUMAs page, where we provide a tract-to-PUMA relationship file.

The Census Bureau’s Geography Boundaries by Year page describes which geographic definitions are used in each release of ACS data. The ACS summary tables have used 2020 census tract definitions since the 2020 5-year release.
