The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 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 2024 to 2025, from $149M to $129M (−13%).
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: 2020 2% · 2021 2%. Grants only. Government contracts and fees sit inside program revenue.
0% of Children's Orthopaedic Surgery Foundatio’s revenue is contributions — more earned-revenue than three-quarters of its peers (7% for the typical peer).

Who funds it, year by year
2017 → 2020: the base held at 1 funder, grant income rose $23k → $38k.
1 of 2 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 96% 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: $132k from one payer (the payer shares this organization's board, largest Children's Sports Medicine Foundation Inc). These are real filings, and they are not money Children's Orthopaedic Surgery Foundatio raised.

How concentrated its funding is
Children's Orthopaedic Surgery Foundatio leans on a few funders — its largest provides 96% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
100% 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 Children's Orthopaedic Surgery Foundatio.
Largest funder’s share by year: 2017 100% · 2019 100% · 2020 100% — broadly stable.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration.

Where its funders are
96% of Children's Orthopaedic Surgery Foundatio'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 $76k that is directly attributable, 100% of it comes from funders outside Massachusetts, across 1 state.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.7M 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.
