The organization over time
Each line starts at 100 in 2019, so what you read is the shape rather than the size: 150 means half as much again as 2019, 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 $3.2M to $3.1M (−3%).
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: 2021 12% · 2023 40%. Grants only. Government contracts and fees sit inside program revenue.
65% of MID AMERICA TRANSPORTATION AND AVIATION MUSEUM’s revenue is contributions — about as donation-reliant as the typical peer (78% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 7 reported years ran a deficit.

Leadership and staff
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
2018 → 2023: the base broadened from 1 funder to 2 funders, grant income fell $25k → $18k.
1 of 3 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 10% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of MID AMERICA TRANSPORTATION AND AVIATION MUSEUM’s funders (the co-funder graph). Association, not causation.

How concentrated its funding is
MID AMERICA TRANSPORTATION AND AVIATION MUSEUM leans on a few funders — its largest provides 86% 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
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. 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 MID AMERICA TRANSPORTATION AND AVIATION MUSEUM.
Largest funder’s share by year: 2018 100% · 2021 100% · 2022 91% · 2023 94% — 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
100% of MID AMERICA TRANSPORTATION AND AVIATION MUSEUM's grant income comes from Iowa funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $10k 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.
