Religiousness across the U.S. in 2013 remained similar to previous years. With 61% of its residents classified as very religious, Mississippi held on to its position as the most religious state, while Vermont, with 22% very religious residents, remained the least religious. The most religious states were in the South, except for Utah, while the least religious states were clustered in New England and the West.
Although there have been minor changes in the rank-order of the most religious and the least religious states between 2008 and 2013, the broad pattern has remained similar year after year. Ten of the 11 most religious states in 2013 are in the South. The exception is Utah, a majority of whose residents identify as Mormons -- the most religious of any major religious group in the country.
The 10 least religious states in 2013 are from two areas -- New England and the West -- plus the District of Columbia. The New England states of Vermont and New Hampshire continue to be the least religious states in the union.
