Religion
What state is the only one with a majority Catholid population/
United States
The First Amendment of the U.S. Constitution guarantees the free exercise of religion and forbids Congress from passing laws respecting its establishment. Christianity is by far the most common religion practiced in the U.S., but other religions are followed, too. In a 2013 survey, 56% of Americans said that religion played a "very important role in their lives", a far higher figure than that of any other wealthy nation. In a 2009 Gallup poll 42% of Americans said that they attended church weekly or almost weekly; the figures ranged from a low of 23% in Vermont to a high of 63% in Mississippi. According to a 2012 survey, 73% of adults identified themselves as Christian, down from 86.4% in 1990. Protestant denominations accounted for 48%, while Roman Catholicism, at 22%, was the largest individual denomination. The total reporting non-Christian religions in 2012 was 6%, up from 4% in 2007. Other religions include Judaism (1.7%), Buddhism (0.7%), Islam (0.6%), Hinduism (0.4%), and Unitarian Universalism (0.3%). The survey also reported that 19.6% of Americans described themselves as agnostic, atheist or simply having no religion, up from 8.2% in 1990. There are also Baha'i, Sikh, Jain, Shinto, Confucian, Taoist, Druid, Native American, Wiccan, humanist and deist communities. Protestantism is the largest group of religions in the United States, with Baptists being the largest Protestant sect, and the Southern Baptist Convention being the largest Protestant denomination in the U.S. Roman Catholicism in the U.S. has its origin in the Spanish and French colonization of the Americas, and later grew due to Irish, Italian, Polish, German and Hispanic immigration. Rhode Island is the only state where the majority of the population is Catholic. Lutheranism in the U.S. has its origin in immigration from Northern Europe. North and South Dakota are the only states in which a plurality of the population is Lutheran. Utah is the only state where Mormonism is the religion of the majority of the population. Mormonism is also relatively common in parts of Idaho, Nevada and Wyoming. The Bible Belt is an informal term for a region in the Southern United States in which socially conservative evangelical Protestantism is a significant part of the culture and Christian church attendance across the denominations is generally higher than the nation's average. By contrast, religion plays the least important role in New England and in the Western United States. As with other Western countries, the U.S. is becoming less religious. Irreligion is growing rapidly among Americans under 30. Polls show that overall American confidence in organized religion is declining, and that younger Americans in particular are becoming increasingly irreligious.
