Are there different sects of Judaism?
Jewish religious movements
Jewish religious movements, sometimes called "denominations" or "branches", include different groups which have developed among Jews from ancient times. Today, the main division is between the Orthodox, Conservative, Reconstructionist, and Reform movements, with several smaller movements alongside them. This denominational structure is mainly present in the United States, while in Israel, the fault lines are between the Orthodox and the non-religious.
American Jews
The survey found that of the 4.3 million strongly connected Jews, 46% belong to a synagogue. Among those households who belong to a synagogue, 38% are members of Reform synagogues, 33% Conservative, 22% Orthodox, 2% Reconstructionist, and 5% other types. Traditionally, Sephardic and Mizrahis do not have different branches (Orthodox, Conservative, Reform, etc.) but usually remain observant and religious. The survey discovered that Jews in the Northeast and Midwest are generally more observant than Jews in the South or West. Reflecting a trend also observed among other religious groups, Jews in the Northwestern United States are typically the least observant.
