The U.S. Department of Health and Human Services organization across 16 Operating and Staff Divisions, plus the proposed 2025 reorganization umbrella offices (flagged). Offices proposed in current reorganizations are flagged. Click any office for its description and Federal Register source. The budget, workforce, and spending tabs cover 14 Operating and Staff Divisions, with the deepest account detail for the Indian Health Service.
Where every number comes from, how the public datasets were fit together, and what this does and does not claim.
Three views of the U.S. Department of Health and Human Services, by Operating Division and by appropriation account or activity, across fiscal years: the money appropriated (budget authority), the workforce that money supports (full-time-equivalent staff, or FTE), and, across the federal government (recreated from USAspending records, with the deepest detail for the Indian Health Service), the money actually committed to recipients (obligations). These are different measures.
Budget authority and workforce come from each Operating Division's annual Congressional Justification of Estimates for Appropriations, the detailed budget each agency sends to Congress, together with the President's Budget. Earlier years are taken from the most recent Justification that restates them, so a single, consistent structure is used per Operating Division. Actual spending comes from USAspending.gov: account-level balances and the account spending breakdown, plus the underlying grant and contract award records. Where a Justification did not publish a staffing number, workforce is estimated from the U.S. Office of Personnel Management's federal employment data.
Every figure is tied to three things: the office that administers it, the appropriation account it flows through, and the fiscal year. That shared backbone lets budget, people, and spending line up for the same office and the same year. Because budget authority, obligations, and FTE (people) measure different things and are shown side by side.
FTE, full-time-equivalent, measures funded work rather than a count of people: one full-year position is one FTE, while a part-time or partial-year position is one person but less than one FTE. Where a Justification published FTE, that number is used as printed. Where it did not, FTE is estimated from federal employment (head count) using a workforce ratio. That estimate carries some error and is not exact, but it is reliable enough to show scale and direction, and estimated values are flagged rather than presented as reported figures.
Account codes are the Treasury account symbols used in the President's Budget. Federal programs are identified by their Assistance Listing numbers (formerly the Catalog of Federal Domestic Assistance), published on SAM.gov. Spending records distinguish grants and other assistance from contracts, and carry recipient-type codes that, used only in aggregate and without naming any recipient, indicate how much funding reaches tribal entities. Agency organization and the proposed reorganizations are drawn from the official Statements of Organization published in the Federal Register.
Budget authority is the appropriated program level, not total budgetary resources. The President's Budget year is a request (proposed), not enacted law. There is not yet a House, Senate, conference, and enacted comparison, because that record is still being collected. Year coverage varies by Operating Division, as noted on each view. Actual spending detail beyond the Indian Health Service is pending additional award-level data. The proposed consolidation of the Administration for Community Living (ACL) into the Administration for Children, Families, and Communities (ACFC) is judicially enjoined (New York v. Kennedy, No. 1:25-cv-00196 (D.R.I.), preliminary injunction July 1, 2025; stay denied); ACL remains a current Operating Division and Congress continues to fund it. This is a research reconstruction built from public federal sources, not an official agency publication.
