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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2023 to 2024, from $9.6M to $15M (+61%).
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 76% · 2018 76% · 2019 80% · 2020 82% · 2021 81% · 2022 81% · 2023 88% · 2024 91%. Grants only. Government contracts and fees sit inside program revenue.

How concentrated its funding is
NATIONAL MARINE SANCTUARY FOUNDATION leans on a few funders — its largest provides 43% of grant income and the top three 63%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
63% 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 NATIONAL MARINE SANCTUARY FOUNDATION.
Largest funder’s share by year: 2017 17% · 2018 35% · 2019 43% · 2020 37% · 2021 28% · 2022 61% · 2023 73% — 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
38% of NATIONAL MARINE SANCTUARY FOUNDATION's funders are still giving 3 years after their first grant; 47% 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
NATIONAL MARINE SANCTUARY FOUNDATION draws 100% of its grant income from funders outside Maryland, across 18 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.1M arriving through sponsors registered in 9 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.
