The organization over time
Each line starts at 100 in 2022, so what you read is the shape rather than the size: 150 means half as much again as 2022, 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: 2024 38%. Grants only. Government contracts and fees sit inside program revenue.
98% of PORTER CO MUSEUM CORPORATION’s revenue is contributions — more reliant on donations than three-quarters of its peers (64% for the typical peer).

Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 2 funders, grant income rose $12k → $48k.
4 of 5 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 57% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

the vertical line marks half of all grant income — 1 funder to its left
57% 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 PORTER CO MUSEUM CORPORATION.
Largest funder’s share by year: 2017 100% · 2018 88% · 2019 56% · 2020 63% · 2021 82% · 2022 83% · 2023 75% — 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
57% of PORTER CO MUSEUM CORPORATION'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 $196k that is directly attributable, 100% of it comes from Indiana funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $255k arriving through sponsors registered in 4 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.
