*New* IPUMS Data Updates: New Boundary Files, Variables, and Crosswalks Across Multiple Projects

IPUMS has announced a series of data updates across its projects. IPUMS NHGIS has released a new version of its GIS boundary files for 1970 census blocks, with wide-ranging improvements to the block definitions for 10 metro areas, including New York, Los Angeles, Chicago, Philadelphia, Detroit, and San Francisco. IPUMS DHS and IHGIS now offer variables and crosswalks that link IHGIS census tables to IPUMS DHS records for geographic units finer than the second administrative level, though downloading them requires GPS authorization from the DHS Program.

IPUMS Time Use has added guidance on the recommended weight for each variable-sample combination in IPUMS ATUS, explained in a recent blog post on the “Weights Tab.” The October ATUS webinar, “Using American Time Use Survey (ATUS) to Study Americans’ Social Lives: Opportunities & Limitations,” hosted by the Maryland Population Research Center, is now available on the IPUMS tutorials page. IPUMS USA has updated several socioeconomic status variables (ERSCOR50, ERSCOR90, EDSCOR50, EDSCOR90, NPBOSS50, and NPBOSS90) for all ACS samples, and PLACENHG is now available for the 1940 full count file. IPUMS CPS now includes variables from the Displaced Worker and Job Tenure supplements fielded in January 2026.
