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 2022 to 2023, from $146k to $298k (+103%).

the vertical line marks half of all grant income — 2 funders to its left
70% 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 FRIENDS OF ORINDA NATURE AREA.
Largest funder’s share by year: 2019 56% · 2020 98% · 2021 97% · 2022 66% · 2023 66% — 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
55% of FRIENDS OF ORINDA NATURE AREA'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 $30k that is directly attributable, 67% of it comes from funders outside California, across 2 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $37k arriving through sponsors registered in 3 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.
