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: 2024 99%. Grants only. Government contracts and fees sit inside program revenue.
99% of MOUNT VERNON PUBLIC LIBRARY’s revenue is contributions — more reliant on donations than three-quarters of its peers (48% for the typical peer).

the vertical line marks half of all grant income — 1 funder to its left
86% 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 MOUNT VERNON PUBLIC LIBRARY.
Largest funder’s share by year: 2019 79% · 2020 100% · 2021 100% — growing more concentrated.
