The organization over time
Each line starts at 100 in 2021, so what you read is the shape rather than the size: 150 means half as much again as 2021, 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.

Government-grant reliance: 2025 34%. Grants only. Government contracts and fees sit inside program revenue.

Who funds it, year by year

How concentrated its funding is
JEFFCO OPEN SPACE FOUNDATION INC leans on a few funders — its largest provides 60% of grant income and the top three 86%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
75% 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 JEFFCO OPEN SPACE FOUNDATION INC.
Largest funder’s share by year: 2019 100% · 2020 100% · 2021 100% · 2022 100% · 2023 59% — 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
60% of JEFFCO OPEN SPACE FOUNDATION 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 $77k that is directly attributable, 100% of it comes from funders outside Colorado, across 6 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $113k arriving through sponsors registered in 2 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.
