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: 2023 14% · 2024 9%. Grants only. Government contracts and fees sit inside program revenue.
40% of EXPLORE CHILDREN'S MUSEUM OF SUN PRAIRIE INC’s revenue is contributions — about as donation-reliant as the typical peer (64% for the typical peer).

the vertical line marks half of all grant income — 3 funders to its left
69% 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 EXPLORE CHILDREN'S MUSEUM OF SUN PRAIRIE INC.
Largest funder’s share by year: 2021 76% · 2022 44% · 2023 49% — diversifying over time.

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 EXPLORE CHILDREN'S MUSEUM OF SUN PRAIRIE INC'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 $63k that is directly attributable, 67% of it comes from Wisconsin funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $83k 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.
