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 $73M to $88M (+21%).
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: 2022 7%. Grants only. Government contracts and fees sit inside program revenue.
2% of AMERICAN OSTEOPATHIC ASSOCIATION’s revenue is contributions — about as donation-reliant as the typical peer (7% for the typical peer).
Surplus & reserves

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

Who funds it, year by year
2017 → 2023: the base narrowed from 6 funders to 3 funders, grant income fell $135k → $50k.
1 of 13 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 0% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $2.3M from 3 payers (the payer shares this organization's board, largest At Still Osteopathic Foundation and Research Institute). These are real filings, and they are not money AMERICAN OSTEOPATHIC ASSOCIATION raised.
From the IRS filings of AMERICAN OSTEOPATHIC ASSOCIATION’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
AMERICAN OSTEOPATHIC ASSOCIATION has a broad base — no single funder exceeds 22% 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
89% 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 AMERICAN OSTEOPATHIC ASSOCIATION.
Largest funder’s share by year: 2017 83% · 2018 62% · 2019 82% · 2020 38% · 2021 100% · 2022 100% · 2023 50% — 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
27% of AMERICAN OSTEOPATHIC ASSOCIATION's funders are still giving 3 years after their first grant; 46% 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
AMERICAN OSTEOPATHIC ASSOCIATION draws 76% of its grant income from funders outside Illinois, across 10 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $32 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. 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.
Against its field
AMERICAN OSTEOPATHIC ASSOCIATION holds deeper cash reserves than three-quarters of the 2,843 health nonprofits its size.
