Methodology notes
Lineage categories represent self-identification and genetic/historical studies. "Mizrahi/Sephardic" = Jewish communities of Middle Eastern and North African origin. "Ashkenazi" = communities of Central/Eastern European origin with Levantine-admixed ancestry. Observance figures are survey estimates; methodologies vary by country. All figures are approximations.
