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 2019 to 2020, from $1.4M to $992k (−29%).
How it's funded, over time

Government-grant reliance: 2020 25% · 2021 14%. Grants only. Government contracts and fees sit inside program revenue.

99% 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 FRIENDS OF QUARRY HILL NATURE CENTER INC.
Largest funder’s share by year: 2017 43% · 2018 53% · 2019 64% · 2020 57% · 2021 86% · 2022 52% · 2023 50% — growing more concentrated.

Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year.

Where its funders are
56% of FRIENDS OF QUARRY HILL NATURE CENTER 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.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $421k arriving through sponsors registered in 5 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.
