The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 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: 2021 11% · 2022 17% · 2023 12% · 2024 7% · 2025 5%. Grants only. Government contracts and fees sit inside program revenue.
10% of JOHN WINTHROP NURSERY SCHOOL CORPORATION’s revenue is contributions — about as donation-reliant as the typical peer (48% for the typical peer).

From the IRS filings of JOHN WINTHROP NURSERY SCHOOL CORPORATION’s funders (the co-funder graph). Association, not causation.

How concentrated its funding is
JOHN WINTHROP NURSERY SCHOOL CORPORATION leans on a few funders — its largest provides 83% of grant income and the top three 95%; 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 JOHN WINTHROP NURSERY SCHOOL CORPORATION.
Largest funder’s share by year: 2017 93% · 2020 98% · 2021 99% · 2022 62% · 2023 67% — 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
95% of JOHN WINTHROP NURSERY SCHOOL 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 $8k that is directly attributable, 100% of it comes from Massachusetts funders.
Funder states come from each funder’s own filing. $163k arriving through sponsors registered in 3 states 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.
