The organization over time
Each line starts at 100 in 2024, so what you read is the shape rather than the size: 150 means half as much again as 2024, 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 at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $81k to $184k (+128%).
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.
100% of Arizona Mining Reform Coalition’s revenue is contributions — more reliant on donations than three-quarters of its peers (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 0 of the last 2 reported years ran a deficit.

From the IRS filings of Arizona Mining Reform Coalition’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
Arizona Mining Reform Coalition leans on a few funders — its largest provides 59% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
59% 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 Arizona Mining Reform Coalition.
Largest funder’s share by year: 2022 73% · 2023 88% — growing more concentrated.
“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
59% of Arizona Mining Reform Coalition's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $62k that is directly attributable, 100% of it comes from funders outside Arizona, across 1 state.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $90k arriving through sponsors registered in 1 state 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.
