MASSACHUSETTS EYE & EAR INFIRMARY

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.

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 6% · 2018 6%. Grants only. Government contracts and fees sit inside program revenue.

Surplus & reserves

Operating surplus or deficit each year, and months of liquidity in hand. 0 of the last 2 reported years ran a deficit.

Who funds it, year by year

2017 → 2023: the base broadened from 28 funders to 42 funders, grant income rose $4.5M → $6.3M.

Left out of every figure on this page: $58M from 11 payers (the payer shares this organization's board, largest Foundation of the Massachusetts Eye and Ear Infirmary Inc). These are real filings, and they are not money MASSACHUSETTS EYE & EAR INFIRMARY raised.

From the IRS filings of MASSACHUSETTS EYE & EAR INFIRMARY’s funders (the co-funder graph). Top 30 of 102 funders by total. Association, not causation.

How concentrated its funding is

MASSACHUSETTS EYE & EAR INFIRMARY has a broad base — no single funder exceeds 14% of grant income, and it takes 5 funders to reach half.

62% 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 MASSACHUSETTS EYE & EAR INFIRMARY.

Largest funder’s share by year: 2017 31% · 2018 27% · 2019 40% · 2020 26% · 2021 24% · 2022 19% · 2023 20% — 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.

Funder states come from each funder’s own filing. $12M arriving through sponsors registered in 6 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.
