A 2013 survey reported that 31% of Americans attend religious services at least weekly. It was conducted by the Public Religion Research Institute with a margin of error of 2.5.[2] In 2006, a world-wide online Harris Poll surveyed 2,010 U.S. adults[59] 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.[3]

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.[60] 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%), which the state with smallest percentage was Vermont (57%).[61]
