US Department of Health and Human Services

Funds health research, public health initiatives, and social services through multiple operating divisions and programs.

HHS is the largest grant-making agency in the US, responsible for enhancing the health and well-being of all Americans through effective health and human services and advances in medicine, public health, and social services. Its direct grant footprint is concentrated in the Office of the Secretary staff divisions — primarily OASH (which administers Title X family planning, women's health, minority health, population affairs, teen pregnancy prevention, and research integrity programs) plus ONC and ASPR. The department's $94.7 billion FY2026 discretionary budget and nearly $2 trillion total budget include all component operating divisions and entitlement programs; these are not attributable to HHS-direct grants. The vast majority of HHS funding flows through independent operating divisions: NIH, CDC, FDA, CMS, HRSA, ACL, ACF, ARPA-H, SAMHSA, IHS, AHRQ, and two new FY2026 consolidations — Administration for a Healthy America (AHA) and Administration for Children, Families, and Communities (ACFC). Each OpDiv should be modeled as a child funder of us-hhs. HHS-OS-direct grants (~19 active NOFOs) are smaller in number but include the flagship Title X Family Planning Services program (~$257M over 5 years, up to 90 awards).
