Yale is the most-Jewish Ivy, but Cornell has the most total Jews

Yale University’s undergrad student body is 27 percent Jewish (1,500 Jewish undergrads out of 5,477 total). Percentage-wise, it narrowly beats out its Ivy League rival Harvard University, which is 25 percent Jewish (1,675 out of 6,694 undergrads). But Cornell University and Columbia University both have more Jews in total — 3,000 and 1,800, respectively.
