The organization over time
Each line starts at 100 in 2024, so what you read is the shape rather than the size: 150 means half as much again as 2024, 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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2025 to 2026, from $275k to $292k (+6%).

Who funds it, year by year
2018 → 2023: the base broadened from 1 funder to 2 funders, grant income fell $5k → $1k.
1 of 3 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 0% 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 WEST NASSAU HISTORICAL SOCIETY INC’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.

WEST NASSAU HISTORICAL SOCIETY INC leans on a few funders — its largest provides 63% 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
63% 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 WEST NASSAU HISTORICAL SOCIETY INC.
Largest funder’s share by year: 2018 100% · 2023 99% — 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
63% of WEST NASSAU HISTORICAL SOCIETY INC's grant income comes from Florida funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $16 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.
