The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 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 $34M to $50M (+47%).
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: 2018 4% · 2019 3% · 2020 5% · 2021 12% · 2022 22% · 2023 2% · 2024 5% · 2025 2%. Grants only. Government contracts and fees sit inside program revenue.
57% of JOSEPH & FLORENCE MANDEL JEWISH DAY SCHOOL’s revenue is contributions — more donation-reliant than the typical peer (23% for the typical peer).
Surplus & reserves

5 of 28 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.
Left out of every figure on this page: $31M from 14 payers (the payer shares this organization's board, largest Jack Joseph and Morton Mandel Supporting Foundation). These are real filings, and they are not money JOSEPH & FLORENCE MANDEL JEWISH DAY SCHOOL raised.
From the IRS filings of JOSEPH & FLORENCE MANDEL JEWISH DAY SCHOOL’s funders (the co-funder graph). Association, not causation.

the vertical line marks half of all grant income — 3 funders to its left
33% 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 JOSEPH & FLORENCE MANDEL JEWISH DAY SCHOOL.
Largest funder’s share by year: 2017 83% · 2018 62% · 2019 49% · 2020 35% · 2021 32% · 2022 22% · 2023 28% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration.

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.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $326k arriving through sponsors registered in 5 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.
