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 25% · 2018 20% · 2019 29% · 2020 29% · 2021 30% · 2022 40% · 2023 22% · 2024 21% · 2025 28%. Grants only. Government contracts and fees sit inside program revenue.
90% of PRESERVATION LEAGUE OF NEW YORK STATE’s revenue is contributions — more reliant on donations than three-quarters of its peers (64% for the typical peer).

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $271k arriving through sponsors registered in 6 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.
