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 2022 to 2023, from $1.8M to $1.6M (−10%).
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 3% · 2021 13% · 2024 5% · 2025 8% · 2026 7%. Grants only. Government contracts and fees sit inside program revenue.
74% of THE PHELPS MANSION MUSEUM’s revenue is contributions — more donation-reliant than the typical peer (64% for the typical peer).
Surplus & reserves

Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 3 funders, grant income rose $22k → $26k.
1 of 7 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 42% 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 THE PHELPS MANSION 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.

THE PHELPS MANSION MUSEUM leans on a few funders — its largest provides 42% of grant income and the top three 87%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
42% 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 THE PHELPS MANSION MUSEUM.
Largest funder’s share by year: 2017 100% · 2020 100% · 2021 100% · 2022 99% · 2023 57% — 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 THE PHELPS MANSION MUSEUM's grant income comes from New York funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $63k 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.
