What Mannheimer Foundation does
Program
To study and conduct research for the advancement of knowledge with respect to human behavioral, sociological and psychological patterns.
$7,999,279 spent
The program described on its FY2025 Form 990-PF.
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 2022 to 2023, from $21M to $23M (+9%).
Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2017 → 2021: the base narrowed from 2 funders to 1 funder, grant income fell $308k → $4k.
1 of 4 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 26% 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 MANNHEIMER FOUNDATION’s funders (the co-funder graph). 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
MANNHEIMER FOUNDATION leans on a few funders — its largest provides 63% of grant income and the top three 97%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
34% 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 MANNHEIMER FOUNDATION.
Largest funder’s share by year: 2017 94% · 2018 80% · 2019 81% · 2020 100% · 2021 100% — 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.
Where its funders are
MANNHEIMER FOUNDATION draws 100% of its grant income from funders outside New Jersey, across 3 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $337k arriving through sponsors registered in 1 state 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.

Federal grants vs contracts are distinguished; state line items keep their reported category. Matched by name + geography (the BMF), so coverage is partial and precision-first.
