An annual survey of American Jews says a bare majority of 51 percent reported membership in a synagogue, though 70 percent identified with a particular branch of Judaism.
The American Jewish Committee poll of 1,008 Jews showed 31 percent thought of themselves as Conservative, 30 percent Reform, 7 percent Orthodox and 2 percent Reconstructionist.
Asked to choose the quality most important to their Jewish identity, 41 percent said "being part of the Jewish people" and 21 percent, "commitment to social justice." Only 13 percent chose "religious observance."
On whether anti-Semitism or intermarriage is the greater threat to Jewish life in the United States, two-thirds chose the former. Respondents also expressed concern over anti-Semitism on American college campuses and in Europe.
The survey, concluded Jan. 5, had a sampling error of plus or minus 3 percentage points.
