The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2021 to 2022, from $2.3M to $3.1M (+37%).
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: 2017 2% · 2018 4% · 2019 4% · 2020 5% · 2021 10% · 2022 2% · 2023 4% · 2024 3%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 8 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 10 funders to 20 funders, grant income rose $487k → $1.3M.
12 of 60 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 16% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of DELAWARE RIVERKEEPER NETWORK’s funders (the co-funder graph). Top 30 of 60 funders by total. Association, not causation. 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.
How concentrated its funding is
DELAWARE RIVERKEEPER NETWORK has a broad base — no single funder exceeds 24% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
Largest funder’s share by year: 2017 47% · 2018 49% · 2019 38% · 2020 33% · 2021 26% · 2022 46% · 2023 40% — 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.
How long its funders stay
41% of DELAWARE RIVERKEEPER NETWORK's funders are still giving 3 years after their first grant; 53% give in more than one year at all.
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. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
59% of DELAWARE RIVERKEEPER NETWORK's grant income comes from Pennsylvania funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.6M arriving through sponsors registered in 7 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.
