The organization over time
Each line starts at 100 in 2023, so what you read is the shape rather than the size: 150 means half as much again as 2023, 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 2023 to 2024, from $2.2M to $2.5M (+15%).
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: 2023 89% · 2024 41%. Grants only. Government contracts and fees sit inside program revenue.

Who funds it, year by year
Grant support over time, funder by funder — shade shows the grant size each year.
1 of 15 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 18% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of Arboretum San Antonio’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
Arboretum San Antonio has a broad base — no single funder exceeds 31% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
“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

Funder states come from each funder’s own filing. $200k 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.
