Nearly every known religion is practiced in the United States, which was founded on the basis of religious freedom. About 83 percent of Americans identify themselves as Christians, according to an ABC poll, while 13 percent replied that they had no religion at all. Another poll in 2012 reported similar findings. It also found that Judaism is the second most-identified religious affiliation, at about 1.7 percent of the population. Only 0.6 percent of respondents identified as Muslim.
