Gallup: “Slightly more than half of Utah residents say they attend religious services every week, more than any other state in the union. Residents in the four Southern states of Mississippi, Alabama, Louisiana and Arkansas are the next most likely to be frequent church attendees, with 45% to 47% reporting weekly attendance. At the other end of the spectrum is Vermont, where 17% of residents say they attend religious services every week.”
“In his recent National Prayer Breakfast speech in Washington, D.C., President Barack Obama noted, ‘The United States is one of the most religious countries in the world — far more religious than most Western developed countries.’ This is certainly true as far as the nation’s average religiosity is concerned, but the fact remains that within the U.S. there are stark geographic differences in religiosity. In some states of the union — Utah and Southern states — roughly half of residents report attending religious services weekly, while in others — mostly in the Northeast and the West — a fourth or less of residents attend weekly.”
