HHS Data Inventory Archive (Through June 2026)
HISTORICAL ARCHIVE (Updated through June 2026): This page contains previous versions of the HHS Data Inventory preserved for historical reference. As of September 2026, HHS modernized the inventory to support routine, dataset-level updates using the DCAT-US v3.0 metadata standard. Because the inventory methodology has evolved, record counts here are not directly comparable to current releases.
To access active data assets, view the primary machine-readable feed at tech.hhs.gov/data.json or search the web interface at Catalog.Data.gov.
The U.S. Department of Health and Human Services (HHS) publishes the HHS Data Inventory—a comprehensive metadata catalog of public and non-public data assets across the Department—in accordance with the Foundations for Evidence-Based Policymaking Act of 2018 (Evidence Act, Pub. L. 115-435). This inventory enhances information discovery, data usability, and government transparency by providing public visibility into data assets from all HHS Divisions.
