The Most & Least Religious US States

Updated Tuesday, Feb. 4 at 9:20 a.m. ET.

States across the South and Utah once again keep their high ranking on an annual list of the most religious U.S. states. Vermont leads the pack of least religious states.

The polling organization Gallup surveyed 174,699 adults across the nation between Jan. 2 and Dec. 29, 2013, asking whether religion is an important part of their daily lives and whether they regularly attend religious services. The results were largely unchanged from years past: Mississippi was the most religious state with 61 percent of its residents labeled as "very religious," while in Vermont, the least religious state, just 22 percent of people were classified as "very religious."
