The organization over time
Each line starts at 100 in 2019, so what you read is the shape rather than the size: 150 means half as much again as 2019, 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 $380M to $310M (−18%).

the vertical line marks half of all grant income — 4 funders to its left
38% 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 HILLWOOD ESTATE MUSEUM & GARDENS.
Largest funder’s share by year: 2017 53% · 2018 43% · 2019 67% · 2020 45% · 2021 26% · 2022 36% · 2023 25% — diversifying over time.
