Does the money reach high-need areas?
Each grant placed by the hardship in its grantee’s ZIP, against the area’s typical level.
US giving: 65% of grant dollars ($1.3B). The need read here covers only this US portion; the 35% that went abroad ($683M) is mapped below.
Its human-services grants (FY22–25, $26.6M) land where the poverty rate runs at 10%, against an area that typically sits at 10%. 32% of those dollars go to grantees based in above-average-need neighborhoods. Its grants skew toward lower-need ZIPs.
How this is measured

398 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. 398 of the 766 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.

Warm introductions · Powered by PlinthPlus
How do I get to The Leona M and Harry B Helmsley Charitable Trust?
Find your warmest path to The Leona M and Harry B Helmsley Charitable Trust through trustees and officers whose names appear on both boards. Search for your organization and Plinth traces the shortest route it can evidence.
Each link is a name appearing on two organizations’ public IRS 990 filings, matched on that name and, where the filings support it, on location. A same-state match has geographic support, which is a second matching feature rather than confirmation that the two are one person; a cross-state one is the likeliest to be two people who share a name. Every hop shows its tier, low-confidence and distant paths are held back rather than guessed, and it is worth confirming the person before you use the introduction.
