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. 3 of the last 9 reported years ran a deficit.

Who funds it, year by year
2019 → 2023: the base narrowed from 2 funders to 1 funder, grant income rose $25k → $80k.
From the IRS filings of MASSACHUSETTS MEDICAL SOCIETY’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
MASSACHUSETTS MEDICAL SOCIETY leans on a few funders — its largest provides 53% 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 MASSACHUSETTS MEDICAL SOCIETY.
Largest funder’s share by year: 2019 80% · 2020 100% · 2023 100% — growing more concentrated.
“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.
Where its funders are
MASSACHUSETTS MEDICAL SOCIETY draws 97% of its grant income from funders outside Massachusetts, across 3 states in all.
