What these numbers do not say

Private-funder figures come from 990 and 990-PF filings as released by the IRS; filings lag reality by one to two years, and organizations below the e-file thresholds are not represented.
A funder appearing here funded this cause historically. It is not a statement that they are accepting applications.
Filings include corrections: voided checks, returned grants and corpus-distribution adjustments appear as negative amounts and are counted as filed. They are a fraction of a percent of the total.
Cause matching is keyword-based against grant purpose text and recipient names; it undercounts grants described in other words.
