A recent Gallup poll found that citizens of Utah attend church more frequently than residents of any other state, with 51 percent of the state's citizens attending church regularly. Church attendance is highest in the South.
This same Gallup poll found that the lowest level of church attendance was found in New England states. States such as Vermont, New Hampshire, Maine and Massachusetts had church attendance rates of 17 percent, 20 percent, 20 percent, and 22 percent, respectively. Levels of church attendance were generally lower in the Northern states, with Washington and Connecticut also having smaller percentages of people attending church on a weekly basis. The states with the highest levels of church attendance were, in order, Utah, Mississippi, Alabama, Louisiana, Arkansas, South Carolina, Tennessee, Kentucky, North Carolina, Georgia, Texas and Oklahoma.
This Gallup poll was conducted in 2014, and it includes over 177,000 respondents. The fact that the southern states are traditionally regarded as Bible Belt states was reflected greatly in the results of the poll. The South also has extremely large Protestant and black populations, which tend to be more observant in terms of religion. Utah's number-one ranking has much to do its large population of Mormons, who practice their faith very devoutly.
