IPUMS Data Updates: USA, NHGIS, and ATUS

Posted: 2/26/2026 (CSDE Awards)

IPUMS announces the release of the latest ACS 5-year summary file data from IPUMS NHGIS, a new tool to help researchers understand linking counts between the ATUS and CPS, and even more geography variables from IPUMS USA.

IPUMS USA has added geography variables, including a new consistent PUMA variable, CPUMA1020, which creates consistent geographic boundaries across 2010 and 2020 PUMA definitions, spanning the 2012–2024 samples. Users can also find new Migration and Place-of-Work variables based on 2023 metropolitan statistical area (MSA) definitions.

IPUMS NHGIS has added the 2020-2024 5-Year Summary File from the American Community Survey (ACS). Nearly 1,200 new summary tables are now available for geographic areas as small as block groups. NHGIS also extended its time series tables to include 2020-2024 ACS 5-year data and added new 2024 GIS boundary files.

IPUMS ATUS has released ATUS-CPS Linking Counts, an interactive tool for exploring the number of ATUS respondents who can be linked to specific months of the CPS. Check out our latest blog post for an introduction of how to use this tool to take advantage of the research potential of the ATUS-CPS linkage
