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 2020 to 2021, from $66M to $79M (+19%).
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 2% · 2018 2% · 2019 0% · 2021 2% · 2022 0% · 2023 1% · 2024 10% · 2025 4%. Grants only. Government contracts and fees sit inside program revenue.

Who funds it, year by year
2017 → 2023: the base broadened from 32 funders to 36 funders, grant income rose $408k → $11M.
11 of 89 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 8% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $2.9M from 4 payers (the payer shares this organization's board, largest Tulsa Community Foundation). These are real filings, and they are not money THE PHILBROOK MUSEUM OF ART INC raised.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.7M arriving through sponsors registered in 9 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.
