Pew Research Center: A Portrait of American Orthodox Jews

"Indeed, in a few ways, Orthodox Jews more closely resemble white evangelical Protestants than they resemble other U.S. Jews. For example, similarly large majorities of Orthodox Jews (83%) and white evangelicals (86%) say that religion is very important in their lives, while only about one-fifth of other Jewish Americans (20%) say the same. Roughly three-quarters of both Orthodox Jews (74%) and white evangelicals (75%) report that they attend religious services at least once a month. "
