והמשכילים יזהירו כזהר הרקיע ומצדיקי הרבים ככוכבים לעולם ועד
Ve-ha-maskilim yazhiru ke-zohar ha-rakia, u-matzdikei ha-rabim ka-kokhavim le-olam va-ed: "The wise shall shine like the brightness of the firmament, and those who lead the many to righteousness like the stars, for ever and ever" (Daniel 12:3). Scroll down through the sky. The first stars rise over Jerusalem and Yavneh; the sky fills over Babylonia, al-Andalus, and the Rhineland, gathers into constellations over Safed, Krakow, and Vilna, and ends thick with light over Jerusalem, Bnei Brak, and New York.
Each star is a sage, and its size is its magnitude: the great lights of the tradition largest, then the major figures, then everyone else, each brightened a little by the number of relationships the census records. Sages appear under the names most people know them by, with the formal name beneath on the card. Hover or tap a star and its ties appear: a teacher and a student, a father and a son, a contemporary or a major influence named in a biography, each line labeled. The sages lie along one luminous band, like the Milky Way: six fields of sky side by side, one for each region, thick with light where the sources name many scholars and thin where they fall silent. As you scroll, the stars near the middle of your screen open out into a constellation with their names; above and below, they fold back into the band. Hover or tap a star to read who the person was and whom they learned from. As you scroll through an age, its constellation forms first out of small connecting stars and takes its name (the Menorah of the Tannaim, the Crown of the Geonim, the Scales of Mussar); the great lights of the age then fly onto it, the rest follow, and on the last stretch they all return to their lines in the band. Through the Acharonim the sky runs in order of time; after 1740 it proceeds movement by movement, early Chassidus and its later courts, the Mitnagdim, German Orthodoxy, Mussar, the Sephardi world, Religious Zionism, and the yeshivot of Israel and America, each with a constellation of its own. At the end, every star takes its place in one spiral galaxy that begins with Hillel and Shammai.
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 galaxy, Hillel and Shammai at its heart, each generation a step further out, each school of thought an arm, are drawn on a page of their own: open One Milky Way.
Drawn from the Great Yeshivas Global Historical Enrollment Census (v72), sheets 06 (Rabbi Biographies), 09 (Rabbi Deep Pass), 11 (Family Connections), and 15 (Core Biography Expansion). Only figures with recorded life dates and a biography are drawn; the remaining census rows join as their research passes are completed. Where a census row gives only a century, the star is placed at its midpoint and marked as approximate.
Hebrew names follow the census as recorded, generally in the Koren style, with familiar places in English. Where a sage is best known by an acronym or the title of a work, it appears in parentheses.

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.
