New Jersey is a very diverse state — both ethnically and religiously, with 3 percent of the population identifying as Muslim, according to the most recent religious landscape study by the Pew Research Center. That’s about the same number of Hindus and half as many Jews (6 percent).
Catholics (34 percent) are by far the largest denominational group, making up about half of all Christians. There are 13 percent evangelical Christians, 12 percent mainline Protestants, 6 percent historically black Protestant churches, 1 percent Mormon, 1 percent Jehovah’s Witnesses, and 1 percent Orthodox Christians.
About 18 percent of New Jerseyans say they are unaffiliated, including 2 percent who are atheists and 3 percent who are agnostics.
