Some aspects of Jewish religious life and culture are widespread among American Jews. But other religious expressions – such as regular attendance at synagogue services and belief in God as described in the Bible – are much less common, according to a new survey.

In fact, based on these more traditional measures of religious observance, Jews in the U.S. are far less religious than U.S. Christians and Americans overall.

For example, 12% of U.S. Jewish adults say they attend religious services weekly or more often, compared with 27% of the general public and 38% of U.S. Christians. And 21% of Jewish adults say religion is very important in their lives, compared with 41% of U.S. adults overall and 57% of Christians.
