Full Breakdown
Yom Kippur Fasting and Prayer Patterns Among Israeli Jews
By Drooid · · How we work
Survey Overview and Key Findings
A recent survey conducted by the Israel Democracy Institute (IDI) reveals that 74 % of Israeli Jews fast on Yom Kippur, with 63 % observing a full fast and 11 % fasting partially. Overall prayer participation stands at 57 % of the Jewish population.
Demographic Breakdown of Fasting
Fasting rates vary markedly across religious affiliation and ethnicity. Among secular Jews, less than half (47 %) fast—28 % fully and 19 % partially—whereas 90 % of non-religious traditional Jews fast (77 % fully, 13 % partially). Haredi, religious, and religious-traditional Jews report 97 %–98 % full-day fasting. Ethnic differences are pronounced: 81 % of Mizrahi Jews fast fully compared with roughly 50.5 % of Ashkenazi Jews. Gender gaps are modest; 65 % of men and 61 % of women fast fully, with partial fasting reported by 13 % of women and 10 % of men. Age analysis indicates the gender gap exists mainly among adults 18–44, disappearing in older cohorts.
Prayer Service Attendance
Among those who attend Yom Kippur services, 51 % choose Orthodox congregations, while only 6 % attend Reform or Conservative services. Overall, 20 %–25 % of Haredi, religious, religious-traditional, and non-religious traditional Jews attend services, alongside 11 % of secular Jews. Men are slightly more likely than women to attend, especially in Orthodox settings (54 % of men vs. 48 % of women). Mizrahi Jews attend prayers at a higher rate (68 %) than Ashkenazi (?50 %) and mixed-background Jews (?51 %). For 18 % of Israeli Jews, Yom Kippur is the sole synagogue visit of the year; this figure rises to 37 % among non-religious traditional Jews.
Context and Observations
Thousands of Jews are expected to gather for selichot services at the Western Wall in Jerusalem ahead of Yom Kippur on September 15, 2026. The survey suggests that health considerations and personal principle, rather than age, primarily explain partial or non-fasting among older respondents.
Limitations and Future Monitoring
The IDI data reflects self-reported practices at a single point in time. Ongoing surveys will be needed to track shifts in fasting and prayer behavior across Israel’s diverse Jewish communities.
