Dollar for dollar, its grants (FY20–25) land where the poverty rate runs at 10%, against an area that typically sits at 12%. 23% of its dollars go to grantees based in above-average-need neighborhoods. Its grants skew toward lower-need ZIPs.

10 grantees tracked through their own filings, 2017–2025.
Each grant beside the grantee’s revenue from every source, year by year.
How this is measured
Counted here: distinct organizations funded across 2017 to 2025, not grant rows in a single year, so this will not match the grant count on the cover. 10 of the 14 grantees resolved in that span have returns of their own we could reconcile.
Each grantee is resolved to its own IRS returns. Association, dated; never a causal claim.
Where the money sits, by cause and then by grantee
