Does the money reach high-need areas?
Each grant placed by the hardship in its grantee’s ZIP, against the area’s typical level.
Its human-services grants (FY17–25, $15.7M) land where the poverty rate runs at 8%, against an area that typically sits at 8%. 33% of those dollars go to grantees based in above-average-need neighborhoods. Its grants skew toward lower-need ZIPs.

How this is measured
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 12 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.
