Christianity is by far the largest religion in the United States; more than three-quarters of Americans identify as Christians. A little more than half of us identify as Protestants, about 23 percent as Catholic and about 2 percent as Mormon.
Figuring out each state’s largest religion is easy; more than three-quarters of Americans identify as Christians. But, make it second-largest and the results get interesting.
In the Western U.S., Buddhists represent the largest non-Christian religious bloc in most states. In 20 states, mostly in the Midwest and South, Islam is the largest non-Christian faith tradition. And in 15 states, mostly in the Northeast, Judaism has the most followers after Christianity. Hindus come in second place in Arizona and Delaware, and there are more practitioners of the Baha’i faith in South Carolina than anyone else.
The Association of Statisticians of American Religious Bodies, which sponsors the U.S. Religious Census every 10 years, mapped out data on religious popularity. Knowing that Christianity was the leader in every state, ASARB highlighted each state’s second-most popular faith.
The data the ASARB release every 10 years are revealing: Adherents to any religious faith — that is, those who actually attend religious services — make up more than half the population in 28 states. Utah has the highest percentage of adherents, at 79 percent of the population, while just over a quarter of Mainers are adherents. North Dakota, Alabama and Louisiana are near the top of the list, while Oregon, Vermont, Alaska, Nevada and Washington sit near the bottom of the rankings.
