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.
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.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 9 reported years ran a deficit.

From the IRS filings of Barstow Humane Society’s funders (the co-funder graph). Top 6 of 8 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
Barstow Humane Society leans on a few funders — its largest provides 36% of grant income and the top three 95%; 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 Barstow Humane Society.
Largest funder’s share by year: 2017 100% · 2018 99% · 2019 67% · 2020 64% · 2021 44% · 2022 47% · 2023 72% — 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.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $89k arriving through sponsors registered in 2 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.
