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.
91% of NATURAL RESOURCES DEFENSE COUNCIL INC’s revenue is contributions — more donation-reliant than the typical peer (90% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 9 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 599 funders to 758 funders, grant income rose $43M → $78M.
101 of 1810 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 38% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $112M from 65 payers (the payer shares this organization's board, largest Foundation for the Carolinas); $20M from 3 payers (an institutional transfer, not a grant programme, largest Tansy Charitable Foundation). These are real filings, and they are not money NATURAL RESOURCES DEFENSE COUNCIL INC raised.

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
NATURAL RESOURCES DEFENSE COUNCIL INC has a broad base — no single funder exceeds 13% of grant income, and it takes 11 funders to reach half.
the vertical line marks half of all grant income — 11 funders to its left
48% 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 NATURAL RESOURCES DEFENSE COUNCIL INC.
Largest funder’s share by year: 2017 10% · 2018 11% · 2019 21% · 2020 10% · 2021 32% · 2022 9% · 2023 20% — 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.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $225M arriving through sponsors registered in 31 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.
