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 96% · 2018 97% · 2019 96% · 2020 95% · 2021 99% · 2022 99% · 2023 98% · 2024 98% · 2025 97%. Grants only. Government contracts and fees sit inside program revenue.
98% of ANN ARBOR DISTRICT LIBRARY’s revenue is contributions — more reliant on donations than three-quarters of its peers (23% for the typical peer).

From the IRS filings of ANN ARBOR DISTRICT LIBRARY’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.

the vertical line marks half of all grant income — 2 funders to its left
55% 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 ANN ARBOR DISTRICT LIBRARY.
Largest funder’s share by year: 2017 79% · 2018 79% · 2019 77% · 2020 56% · 2021 92% · 2022 98% · 2023 99% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $51k arriving through sponsors registered in 2 statesis 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. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
