The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2020 22% · 2021 16%. Grants only. Government contracts and fees sit inside program revenue.
17% of CLARKE HISTORICAL MUSEUM’s revenue is contributions — more earned-revenue than three-quarters of its peers (64% for the typical peer).
Surplus & reserves

Who funds it, year by year
2017 → 2023: the base broadened from 2 funders to 6 funders, grant income rose $14k → $63k.
2 of 7 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 24% 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 CLARKE HISTORICAL MUSEUM’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
CLARKE HISTORICAL MUSEUM leans on a few funders — its largest provides 47% of grant income and the top three 85%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
77% 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 CLARKE HISTORICAL MUSEUM.
Largest funder’s share by year: 2017 59% · 2018 84% · 2019 54% · 2020 66% · 2021 71% · 2022 68% · 2023 36% — diversifying over time.
“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
100% of CLARKE HISTORICAL MUSEUM's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $53k arriving through sponsors registered in 2 states 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.
