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. 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: 2017 66% · 2018 56% · 2019 40% · 2020 49% · 2021 57% · 2022 73% · 2023 44% · 2024 61% · 2025 63%. Grants only. Government contracts and fees sit inside program revenue.
95% of ARUNDEL RIVERS FEDERATION INC’s revenue is contributions — more donation-reliant than the typical peer (88% for the typical peer).

From the IRS filings of ARUNDEL RIVERS FEDERATION INC’s funders (the co-funder graph). Top 30 of 34 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
ARUNDEL RIVERS FEDERATION INC has a broad base — no single funder exceeds 22% 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
65% 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 ARUNDEL RIVERS FEDERATION INC.
Largest funder’s share by year: 2017 33% · 2018 32% · 2019 41% · 2020 44% · 2021 42% · 2022 34% · 2023 39% — growing more concentrated.
“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

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
66% of ARUNDEL RIVERS FEDERATION INC's grant income comes from Maryland funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $712k arriving through sponsors registered in 6 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.
