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.
100% of YIMBY ACTION’s revenue is contributions — more reliant on donations than three-quarters of its peers (61% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 1 of the last 8 reported years ran a deficit.

Left out of every figure on this page: $2.1M from one payer (the payer shares this organization's board, largest Yes In My Back Yard). These are real filings, and they are not money YIMBY ACTION raised.
From the IRS filings of YIMBY ACTION’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
YIMBY ACTION leans on a few funders — its largest provides 41% of grant income and the top three 92%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
99% 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 YIMBY ACTION.
Largest funder’s share by year: 2019 100% · 2020 54% · 2021 83% · 2022 86% · 2023 44% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration.
