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 $11M to $13M (+20%).
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.

Who funds it, year by year

Left out of every figure on this page: $881k from 2 payers (the payer shares this organization's board, largest Bf Wirt Museum Fd). These are real filings, and they are not money MAHONING VALLEY HISTORICAL SOCIETY raised.

In-state vs out-of-state, by year
