Updated September 24, 2026. Read from IRS Form 990-PF e-file data. Public domain (U.S. government work). Grants are as each foundation reported them to the IRS on its Form 990-PF. Grants to individuals are left out. A grant has a cause only where the recipient's name and city match one organization in the IRS Business Master File, and the cause is that organization's NTEE major group.
