From the grants private foundations list in their IRS tax filings (Form 990-PF, tax years 2019 to 2025), as of Oct 31, 2026. Grants to individuals are left out. A grant counts for the county of the organization that received it, wherever the foundation is based. The typical grant is the middle one. Program areas come from each organization's IRS category and the stated purpose of the grant, so those figures are estimates. A foundation can ask to be left off this page by emailing contact@grantassembly.com.
