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 2022 to 2023, from $46M to $110M (+141%).
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 97% · 2018 98% · 2020 98% · 2021 99% · 2022 99% · 2023 99% · 2024 100% · 2025 99%. Grants only. Government contracts and fees sit inside program revenue.
99% of HARBOR DEVELOPMENTAL DISABILITIES FOUNDATION’s revenue is contributions — more reliant on donations than three-quarters of its peers (17% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 8 reported years ran a deficit.

the vertical line marks half of all grant income — 1 funder to its left
96% 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 HARBOR DEVELOPMENTAL DISABILITIES FOUNDATION.
Largest funder’s share by year: 2017 100% · 2018 100% · 2019 100% · 2020 100% · 2021 100% · 2022 99% · 2023 100% — broadly stable.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $15k 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.
