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. Members of the Evangelical Lutheran Church 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. In the West, Buddhism is the largest non-Christian religion in 13 states. Judaism is the largest non-Christian religion in 15 states, mostly in the Northeast. Hinduism reigns in two—Delaware and Arizona. And the Baha’i claim South Carolina.
Brown and orange signify high diversity, while blue and blue-green signify those with very low religious diversity. Counties in many Western states and some New England states have high diversity, while there are pockets of low diversity throughout the middle of the country, Utah and the South.
The counties with the highest rate of religious participation, with red being the most and white the lowest. Utah, the Midwest and parts of the South reign supreme. Religious participation was lowest in California’s Alpine County (4.3 percent), Hawaii’s Kalawao County (3.3 percent) and Nevada’s Esmeralda County (3.1 percent). The latter two have incredibly small populations, so are easily distorted by the religious inaction of a few.
This table shows those counties with the highest number of congregations—defined as regular religious group meetings—per 10,000 people. The numbers were lowest in New York’s Bronx and Richmond counties, Michigan’s Macomb County and Nevada’s Clark County, where there were only four congregations per 10,000 people.
