Washington Post The Catholic church (blue) and Southern Baptists (red) dominate the map below, which marks the religion with the largest number of adherents in every American county. Blanketed red, the Bible Belt is alive and well. Evangelicals in orange can lay claim to a smattering of Midwestern and Western counties, while Mormonism (gray) is, unsurprisingly, the largest religion in every Utah county and in chunks of Utah’s neighboring states.
Islam is the largest non-Christian religion in the nation, claiming 20 states scattered mostly throughout the Midwest and South…with the greatest increases being recorded AFTER 9/11.
