New York Historical Society

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.

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 26% · 2018 3% · 2019 3% · 2020 3% · 2021 8% · 2022 12% · 2023 8% · 2024 2% · 2025 9%. Grants only. Government contracts and fees sit inside program revenue.

Surplus & reserves

Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 9 reported years ran a deficit.

Who funds it, year by year

2017 → 2023: the base broadened from 124 funders to 191 funders, grant income rose $5.8M → $20M.

34 of 436 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 31% 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 New York Historical Society’s funders (the co-funder graph). Top 30 of 436 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

New York Historical Society has a broad base — no single funder exceeds 9% of grant income, and it takes 11 funders to reach half.

34% 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 New York Historical Society.

Largest funder’s share by year: 2017 20% · 2018 11% · 2019 25% · 2020 13% · 2021 15% · 2022 11% · 2023 12% — 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

46% of New York Historical Society's funders are still giving 3 years after their first grant; 59% give in more than one year at all.

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. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.

Where its funders are

66% of New York Historical Society's grant income comes from New York funders.

Funder states come from each funder’s own filing. $36M arriving through sponsors registered in 18 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.
