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.

PRINCETON, NJ — 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.

These state-by-state results are based on more than 174,000 interviews conducted as part of Gallup Daily tracking in 2013, including more than 500 interviews conducted in each state and 442 in the District of Columbia.

Gallup classifies Americans as very religious if they say religion is an important part of their daily lives and that they attend religious services every week or almost every week. More than four in 10 Americans nationwide (41%) fit this classification in 2013. Twenty-nine percent of Americans were nonreligious, saying religion is not an important part of their daily lives and that they seldom or never attend religious services. The remaining 29% were moderately religious, saying religion is important in their lives but that they do not attend services regularly, or that religion is not important but that they still attend services.

Implications

The U.S. remains a religious nation — with about seven in 10 Americans classified as very or moderately religious — and the nation’s residents as a whole are about as religious now as they were in 2008. The religiousness of the nation’s residents, however, does vary substantially by state and region. The most religious areas continue to be the South, the state of Utah, and the Midwestern Plains states, while the least religious areas are mostly in New England, the Pacific Northwest, and other Western states.

These regional variations are quite stable and look generally the same now as they did six years ago. They reflect basic state cultures that are highly persistent, even as states experience demographic changes through births, deaths, and migration.
