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: 5% of grant dollars ($475k). The need read here covers only this US portion; the 95% that went abroad ($9.8M) is mapped below.
Dollar for dollar, its grants (FY21–25) land where the poverty rate runs at 11%, against an area that typically sits at 7%. 99% of its dollars go to grantees based in above-average-need neighborhoods. Most of its grants land in higher-need ZIPs.
How this is measured
Beyond the US: 95% of all-years giving ($9.8M)

Where the work is directed
The same grants placed two ways: where each recipient sits, and where its stated purpose sends the money.
About 6% of Cockayne’s grant dollars are earmarked for a different county than the recipient’s own address.
How this is measured

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.

Co-funders
Grantmakers whose grantees overlap with this funder’s far more than size alone predicts. Closer means stronger alignment; arcs show where they also fund each other. Here they form a tightly interlocked group: most of these funders back each other's grantees too.

How do I get to Cockayne?
Find your warmest path to Cockayne 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.
