While American and Israeli Jews live in widely divergent geographies and settings, Yom Kippur fasting rates may be significantly the same. An almost identical majority of Jews in America and Israel may fast on Yom Kippur.
American Jews were asked whether they fast on Yom Kippur and 59 percent reported that they did on the 2000-1 National Jewish Population Survey with an estimated sampling error of 2%.
Asking a person before Yom Kippur whether they fast or asking a person after Yom Kippur if they fasted are two very different things. Intention versus actual performance.
Its not out of the realm of possibility that some Israelis who meant to fast, didn’t and the actual fasting percentage is even lower than the average 62.6% and could be as low as 57% while the American rate could be as high as 61%. Unfortunately, the time periods are not identical and its not clear whether Israel is trending toward more observance and the U.S. to less among its Jews on Yom Kippur.
