MACKINAC ISLAND MEDICAL CENTER

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 27% · 2018 26% · 2019 59% · 2020 61% · 2021 37% · 2022 42% · 2023 48% · 2024 47%. Grants only. Government contracts and fees sit inside program revenue.

Surplus & reserves

Operating surplus or deficit each year, and months of liquidity in hand. 1 of the last 8 reported years ran a deficit.

Who funds it, year by year

2017 → 2023: the base broadened from 2 funders to 4 funders, grant income rose $100k → $321k.

1 of 6 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: $979k from one payer (the payer shares this organization's board, largest Mackinac Island Community Foundation). These are real filings, and they are not money MACKINAC ISLAND MEDICAL CENTER raised.

From the IRS filings of MACKINAC ISLAND MEDICAL CENTER’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

MACKINAC ISLAND MEDICAL CENTER leans on a few funders — its largest provides 92% of grant income and the top three 100%; half comes from just 1 funder.

92% 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 MACKINAC ISLAND MEDICAL CENTER.

Largest funder’s share by year: 2017 100% · 2018 100% · 2019 98% · 2020 100% · 2021 100% · 2022 78% · 2023 78% — 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.

Where its funders are

93% of MACKINAC ISLAND MEDICAL CENTER's grant income comes from Michigan funders.

Funder states come from each funder’s own filing. $59 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.
