How this is measured
How this is measured
1 grantees tracked through their own filings, 2019–2024.
Each grant beside the grantee’s revenue from every source, year by year.
How this is measured
Counted here: distinct organizations funded across 2019 to 2024, not grant rows in a single year, so this will not match the grant count on the cover.
Each grantee is resolved to its own IRS returns. Association, dated; never a causal claim.
Each grantee by its size and the funder’s share of it; top left is load-bearing
Grantee by grantee: a decade per organization, before and after funding
A decade per grantee: revenue shaded, grants as bars, all rows on one timeline.
How much its grantees rely on government
Each dot is one organization Mill Valley Historical Society funds: left to right is the share of its income from government, bottom to top the share from Mill Valley Historical Society. Bigger dots raise more.

How do I get to Mill Valley Historical Society?
Find your warmest path to Mill Valley Historical Society 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.
