The organization over time
Each line starts at 100 in 2021, so what you read is the shape rather than the size: 150 means half as much again as 2021, 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 $70k to $48k (−31%).
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.
82% of Rock River Coalition Inc’s revenue is contributions — about as donation-reliant as the typical peer (88% for the typical peer).

Who funds it, year by year
2020 → 2023: the base held at 4 funders, grant income rose $18k → $20k.
2 of 7 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 3% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of Rock River Coalition Inc’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.
How concentrated its funding is
Rock River Coalition Inc leans on a few funders — its largest provides 33% of grant income and the top three 70%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
50% 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 Rock River Coalition Inc.
Largest funder’s share by year: 2020 56% · 2021 99% · 2022 62% · 2023 42% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. 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.
Where its funders are
66% of Rock River Coalition Inc's grant income comes from Wisconsin funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $6k arriving through sponsors registered in 2 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. 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.
