Funders are ordered by how much of their overall giving goes to social science work in Washington, D.C., not by dollar totals alone — a foundation that concentrates its giving here is usually a better prospect than a larger one for which this is a rounding error. 14 of the funders counted here are donor-advised fund sponsors, which grant on behalf of individual donors and accept no applications; they are marked and ranked last.

About This Data

A grant appears here when a funder reported it on its IRS Form 990 and the recipient organization is classified under the NTEE group covering social science work, with an address in Washington, D.C.. Grants are counted from the 2025 filing year backward.

Some 990 grant schedules list a recipient by name and address without an EIN, and those grants cannot be matched to a classification — so the totals above represent identifiable social science funding in Washington, D.C., not every dollar that reached the sector. Figures are a floor, not a ceiling.
