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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2020 to 2021, from $31M to $43M (+40%).
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: 2020 11%. Grants only. Government contracts and fees sit inside program revenue.
89% of CENTER FOR BIOLOGICAL DIVERSITY INC’s revenue is contributions — more reliant on donations than three-quarters of its peers (67% for the typical peer).

From the IRS filings of CENTER FOR BIOLOGICAL DIVERSITY INC’s funders (the co-funder graph). Top 30 of 449 funders by total. 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
CENTER FOR BIOLOGICAL DIVERSITY INC has a broad base — no single funder exceeds 19% of grant income, and it takes 6 funders to reach half.
the vertical line marks half of all grant income — 6 funders to its left
62% 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 CENTER FOR BIOLOGICAL DIVERSITY INC.
Largest funder’s share by year: 2017 65% · 2018 29% · 2019 26% · 2020 23% · 2021 23% · 2022 17% · 2023 15% — 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.
How long its funders stay
51% of CENTER FOR BIOLOGICAL DIVERSITY INC's funders are still giving 3 years after their first grant; 59% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
55% of CENTER FOR BIOLOGICAL DIVERSITY INC'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 $43M that is directly attributable, 97% of it comes from funders outside Arizona, across 41 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $52M arriving through sponsors registered in 28 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.
