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 2019 to 2020, from $126M to $161M (+28%).
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: 2017 0% · 2018 1% · 2019 1% · 2020 0% · 2021 0% · 2022 0%. Grants only. Government contracts and fees sit inside program revenue.
40% of AMERICAN ACADEMY OF ORTHOPAEDIC SURGEONS’s revenue is contributions — more reliant on donations than three-quarters of its peers (7% for the typical peer).
Surplus & reserves

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

95% 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.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.3M arriving through sponsors registered in 4 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.
