The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 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 2021 to 2022, from $5.4M to $5.0M (−7%).
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: 2017 30% · 2018 28% · 2019 34% · 2020 48% · 2021 43% · 2022 49% · 2023 39% · 2025 33%. Grants only. Government contracts and fees sit inside program revenue.
56% of NASSAU COUNTY MUSEUM OF ART’s revenue is contributions — about as donation-reliant as the typical peer (63% for the typical peer).

From the IRS filings of NASSAU COUNTY MUSEUM OF ART’s funders (the co-funder graph). Top 30 of 79 funders by total. 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
NASSAU COUNTY MUSEUM OF ART has a broad base — no single funder exceeds 31% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
30% 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 NASSAU COUNTY MUSEUM OF ART.
Largest funder’s share by year: 2017 83% · 2018 53% · 2019 27% · 2020 22% · 2021 29% · 2022 29% · 2023 15% — 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.
How long its funders stay

Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year.

Where its funders are
NASSAU COUNTY MUSEUM OF ART draws 58% of its grant income from funders outside New York, across 8 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $742k arriving through sponsors registered in 5 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.
