What it funded, over time
Every grant placed by its stated purpose and the recipient’s mission, by year, FY2017 to 2025.
Where the money goes
Grants by size, and the largest recipients.

|---|---|
| HOUSTON METHODIST HOSPITAL FOUNDATION | $1,500 |
| MD ANDERSON CANCER CENTER | $1,082 |

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 (FY17–24, $33k) land where the poverty rate runs at 16%, against an area that typically sits at 11%. 100% of those dollars go to grantees based in above-average-need neighborhoods. Most of its grants land in higher-need ZIPs.

8 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. 8 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.
