The organization over time
Each line starts at 100 in 2019, so what you read is the shape rather than the size: 150 means half as much again as 2019, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2020 to 2021, from $358k to $442k (+24%).
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: 2019 31% · 2020 38% · 2021 38% · 2022 31% · 2023 22% · 2024 21% · 2025 24%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 0 of the last 7 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 2 funders, grant income rose $1k → $10k.
2 of 6 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 30% 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 CLARK COUNTY HISTORICAL 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
CLARK COUNTY HISTORICAL SOCIETY leans on a few funders — its largest provides 31% of grant income and the top three 70%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
68% 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 CLARK COUNTY HISTORICAL SOCIETY.
Largest funder’s share by year: 2017 100% · 2018 100% · 2019 100% · 2020 100% · 2021 40% · 2022 80% · 2023 79% — 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
99% of CLARK COUNTY HISTORICAL SOCIETY's grant income comes from Washington funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $16k 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.
