What it costs to build a Jewish life.

Ḥeshbon is a data project on how Jewish life is paid for. Each season takes a single domain and stays with it, measuring what the community assumes against tax filings, benchmarking panels and price data. Season 1 covered Jewish education. Season 2, on household affordability, is live. Season 3, on communal giving, has its first pieces up. Season 4 prices a life in Israel.

Household Affordability

Season 1 measured institutions. Season 2 measures households, looking past what a school charges to what a family actually pays across all of it.

A school can hold tuition flat and still price a family out, because tuition is only one line. Camp, dues, food and housing are the rest, and Season 2 adds them up.

Financial Risk · 3 min readWhite paper

Which Jewish day schools are actually in financial trouble?

Almost every private school spends more than tuition brings in, which is what fundraising exists to cover. The question is who still runs short once the appeal is in. Comparison schools do in 37% of years and Orthodox day schools in 65%, and those Orthodox schools carry 0.7 months of reserve against a comparison median of 6.4.

Growth stops saving most schools money at about 150 students. Does it stop saving these?

For a typical independent school, growing past about 150 students stops lowering the cost per child. Jewish day schools appear to keep saving well beyond that, which turns enrollment growth into a cost strategy available almost nowhere else.

Day school tuition rises about 4% a year. Does it track inflation?

Five schools hold nearly 40% of the endowment. Does that buy their families more aid?

Five schools hold about 40% of all reported endowment wealth, which looks like the core problem. Their tax filings show tuition aid running at nearly the same level everywhere. What separates schools is whether they have any cushion at all.

Leadership Pay · 3 min read

Revenue at these schools grew about 8% a year. Did executive pay follow?

Nonprofit pay theory says compensation rises with size and growth, so the fastest-growing schools should pay the most. Orthodox and Chareidi schools grew revenue by roughly 8% a year while executive pay rose about 1%, which is a real cut once inflation is counted.

Boards benchmark head-of-school pay against tuition. Does tuition predict the pay?

Across 134 identified heads of school, what a school charges predicts almost nothing about what it pays its head. Revenue predicts a great deal, correlating with pay at r = 0.60 against 0.15 for tuition. Boards are anchoring on the number that is easy to look up rather than the one that matters.

Federation and Charitable Giving

Where communal money comes from. Who decides where it goes. And how much has moved away from federated campaigns.

The premise. Seasons 1 and 2 end in the same place: philanthropy closes the gap. Season 3 looks at the philanthropy. The campaign, the family foundation, the donor-advised fund. Allocation decisions are in the record. This reads them.

Aliyah and Living in Israel

The other seasons price Jewish life where the reader already is. Season 4 follows the family that leaves, and asks what it costs to arrive and to stay.

The premise. A move to Israel resets every line at once: salary, housing, schooling, health cover and the support a new arrival receives for a limited window. Season 4 prices the first years of a life there, and sets them against the life that was left behind.

Season 2 · Household Affordability

How Season 2 gets built

Season 1 read what institutions report. Season 2 rebuilds the same number from the household side, priced from public data rather than survey recall.

The basket

One representative family, priced line by line across school, camp, dues, food and housing, with a published source behind every line.

Several communities

The same basket repriced across several communities, so the differences reflect where a family lives rather than one school's rate card.

Against income

Each total is set against household income, to show what share of a year participation actually takes.

Who exits

Enrollment records trace where families leave, then test whether price predicts the exit.

Season 2 is in development. These describe the method; the figures follow once the household data is assembled.
