The Atlas

והמשכילים יזהירו כזהר הרקיע

Ve-ha-maskilim yazhiru ke-zohar ha-rakia, "the wise shall shine like the brightness of the firmament" (Daniel 12:3)

The rest of Ḥeshbon counts what Jewish life costs now. The Atlas is for the other kind of question: where Jews have lived, how many of them there were, who taught whom, and where they went to pray, drawn rather than tabulated.

Eight plates to begin with. Each drawing below is the plate's own data, reduced to fit on this page; open any one and the full figure is waiting.

  1. 526 sages as stars, six fields of sky across, time running downward, and the 318 ties the census records drawn between them
    Plate I

    The Sky of Sages

    ומצדיקי הרבים ככוכבים לעולם ועד

    U-matzdikei ha-rabim ke-khokhavim le-olam va-ed, "and those who turn the many to righteousness, like the stars forever" (Daniel 12:3)

    A descent through a night sky, time running downward and six fields of sky side by side, one for each region. Each star is a sage, its size an editorial magnitude and its brightness the number of ties the census records. Choose a star and its lines appear: a teacher, a father, a contemporary named in a biography. Each age gathers into a constellation of its own and then returns to the band.

    One Milky Way

    הלל ושמאי קבלו מהם

    Hillel ve-Shammai kiblu mehem, "Hillel and Shammai received from them" (Avot 1:12)

    The same stars regathered into a single spiral you can turn. Hillel and Shammai sit at the core, each generation lies one step further out, each school of thought is an arm, and the arms rise above or fall below the plane by camp: the Chassidic courts above, the Lithuanian yeshivot and Mussar below, the Sephardi line near the plane. Every recorded tie pulls its two stars together, so the arms that learned from one another lean toward each other.

    Am Olam

    עם עולם

    Am Olam, "an eternal people"

    A world map that plays. Every community the sources can place, sized by how many Jews lived in it, from the first exile to this year. Press play and the map moves with the story: the massacres and the expulsions flare where they happened and leave a mark that stays, the migrations draw themselves where a source supports them, and the timeline underneath carries the whole four thousand years at once.

    Yeshiva Atlas

    מקום תורה

    Mekom Torah, "a place of Torah" (Avot 4:14)

    Where Torah was learned, drawn on vellum, from the guilds of the prophets to the kollelim of this year. Each dot is an institution with its own panel of observations and sources; a destroyed yeshiva burns and then leaves ash for forty years. Under the map the piece asks how large the yeshivot actually were, and answers that the great Lithuanian houses were, for their time, institutions of a few hundred.

    שארית ישראל

    She'erit Yisrael, "remnant of Israel," the name the first congregation took

    Where today's American congregations began. Press play and the years run from the first English colony in 1585: the colonies shade in and become states, the immigration routes enter from the right edge in the colors of their source, and a dot drops onto the map for each congregation in the year it claims for itself. Shearith Israel in New York is the first in 1654, and it stands alone in the city for 171 years.

    Congregations Today by Denomination

    מקום קבוע לתפילה

    Makom kavua li-tfila, "a fixed place for prayer"

    The same census held still. Every congregation listed as active today is one dot, and the dots regroup as you scroll: into slices by movement, into a timeline by founding year, onto the map, and then into columns by the kind of county around them, by how the county voted in 2024, by its median income and by its reported rate of violent crime. Pick one movement in the key and follow it through every view.

    Where American Jews Are

    ופרצת ימה וקדמה וצפנה ונגבה

    U-faratzta yama va-kedma ve-tzafona va-negba, "and you shall spread out to the west, the east, the north and the south" (Genesis 28:14)

    A spike for every county, standing on an oblique map of the country. Switch the map to community growth and the spikes split in two: gains rise above the ground and declines hang below it, measured against the growth of the state around them if you ask for that. Shade the counties by the 2024 vote, by income, by how rural they are or by five other measures, and the chart underneath sets where American Jews live against where all Americans live.

    Three Centuries in Three Minutes

    ואעשך לגוי גדול

    Ve-e'escha le-goy gadol, "and I will make of you a great nation" (Genesis 12:2)

    A film of the same country filling up. Twenty-three refugees land at New Amsterdam in 1654 and the map runs forward at about a year a second: towns until 1877, then states, then in 2024 the states break apart into counties. Pink lines bring arrivals in from the direction they came, violet rings mark the moves made inside the country, and the band along the foot names the law or the event of the moment. Under the film sit the counts it rests on and twelve documents, from the Newport congregation's letter to Washington to the front page of the morning after the Triangle fire.

The census behind the first two plates

Plates I and II read one file: the Great Yeshivas Global Historical Enrollment Census, sheets 06, 09, 11 and 15. Only figures with recorded life dates and a biography are drawn, and where a row gives a century rather than a year the star is placed at an approximate lifetime and marked as such. The two plates share the file, so a correction to it corrects both.

What the lines claim

A line is a relationship the census records, which is not the same as a relationship that happened. Teacher and student links in the rabbinic period rest on the tradition as it was written down later; the magnitudes and the placement of the schools are editorial, and sit in one table in the data so that they can be argued with.

Four files

Plates I, II and IV read the Great Yeshivas census; Plate III reads a second file of 4,254 places and 16,566 population figures, with its own 2,515 sources; Plates V and VI read a third, the U.S. Synagogue Census, version 83 of October 2026, whose 3,023 rows are mostly congregations that exist today. That last one undercounts the immigrant era badly, since thousands of synagogues of those years have since closed and never entered the file. Plates VII and VIII read a fourth: the county estimates of Comenetz and Sheskin for 2024, the American Jewish Year Book's own tables back to 1899, and the first national count of 1877. Each plate states its own limits at the foot, and the figures are only ever as good as the row behind them.

About the drawings on this page

Every figure above is drawn from the same files the plates read, reduced at build time so that the page stays light: the outlines are simplified, the smallest communities are left out of Plate III, and Plate IV counts places where the plate counts institutions. A figure here and the plate it points at can therefore differ in detail while resting on the same rows, and a correction upstream reaches both on the next build.

חשבון, an accounting

Evidence where anecdote has been doing the work: what a Jewish household or a Jewish institution actually pays, and who decides. Most of these datasets did not exist until a piece needed them. Each one is published alongside the work, with its sources and its limits, so you can check the arithmetic yourself.

The figures here are estimates built from public filings, published price pages and survey samples, and every piece states its own sources, sample sizes and limits in place. Tax filings run a year or more behind and get restated, posted prices change without notice, and a percentage describes the sample observed rather than the whole field. Several rest on small denominators or on voluntary reporting, noted where they appear. Where a number is our own arithmetic rather than a published one, the piece says so and shows the working.

Nothing here audits an individual institution or a person, and naming an organization is not a finding about its conduct. Ḥeshbon is independent of every body named on this site. None has reviewed, approved or funded the work, and where a ranking uses another organization's published figures as an input, that organization has not endorsed the result.

This is research rather than financial, tax, legal or immigration advice, and no one should decide about their own money on these pages alone. Israeli figures are current as of August 2026, at roughly three shekels to the dollar, and Israeli tax and benefit rules move faster than that. Corrections are made on the piece itself and noted there. If something here is wrong, write and it gets fixed.
