Who funds it, year by year
2018 → 2023: the base held at 1 funder, grant income fell $16k → $2k.
1 of 3 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 53% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of TRINIDAD MUSEUM SOCIETY’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
TRINIDAD MUSEUM SOCIETY leans on a few funders — its largest provides 53% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
53% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund TRINIDAD MUSEUM SOCIETY.
Largest funder’s share by year: 2018 100% · 2021 83% · 2022 100% · 2023 100% — broadly stable.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Where its funders are
53% of TRINIDAD MUSEUM SOCIETY's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $14k that is directly attributable, 100% of it comes from funders outside California, across 2 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $16k arriving through sponsors registered in 1 state is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
