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 10% · 2018 12% · 2019 15% · 2020 35% · 2021 20% · 2022 89% · 2023 23% · 2024 5%. Grants only. Government contracts and fees sit inside program revenue.
81% of THE THEATRE MUSEUM CORPORATION’s revenue is contributions — more reliant on donations than three-quarters of its peers (10% for the typical peer).

How concentrated its funding is

the vertical line marks half of all grant income — 1 funder to its left
100% 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 THEATRE MUSEUM CORPORATION.
Largest funder’s share by year: 2017 33% · 2018 66% · 2019 72% · 2020 76% · 2021 44% · 2022 44% · 2023 93% — growing more concentrated.

These figures are read directly from the CRA's published T3010 data: this organization’s own return for FY2024 (financials across 2017–2024), and the filings of 15 funders that report grants to it. “On record” means captured in the filings we have parsed — a funder that does not e-file, or whose grant detail is not itemized, will not appear. Filings run roughly 12–24 months behind. Trends on this page end at FY2023, the last fiscal year that has finished arriving; later years are shown and marked, and move no figure.
