List of U.S. states and territories by religiosity

The degree of religiosity in the population of the United States can be compared to that in other countries and compared state-by-state, based on individual self-assessment and polling data.

Methodologies

The Gallup Poll assesses religiosity around the world, asking "Is religion important in your daily life?" and in the United States by state, asking the degree to which respondents consider themselves to be religious. The Pew Research Center and Public Religion Research Institute have conducted studies of reported frequency of attendance to religious service. The Harris Poll has conducted surveys of the percentage of people who believe in God.

A 2013 survey by the Public Religion Research Institute reported that 31% of Americans attend religious services at least weekly. In 2006, a world-wide online Harris Poll surveyed 2,010 U.S. adults and found that 26% of those surveyed attended religious services "every week or more often", 9% went "once or twice a month", 21% went "a few times a year", 3% went "once a year", 22% went "less than once a year", and 18% never attend religious services. A 2013 Harris Poll reported an 8% decline in a belief in God, since a prior 2009 poll.

According to a 2011 Gallup poll, the state with the greatest percentage of respondents identifying as "very religious" was Mississippi (59%), and the state with the smallest percentage were Vermont and New Hampshire (23%), while Florida (39%) and Minnesota (40%) were near the median. A 2014 Pew Research poll found that the states with the greatest percentage of respondents who stated that religion was "very important" or "somewhat important" to their lives were Alabama (90%) and Louisiana (90%), while the state with the smallest percentage was Vermont (57%).
