Most and Least Religious States

How religious are Americans? It depends, according to a Gallup analysis of religious fervor by state and region. Gallup identifies the "very religious" as those who say religion is important to them and they attend religious services weekly or almost weekly. By state, the percentage of the population that is "very religious" ranges from a low of 16 percent in Vermont to a high of 59 percent in Mississippi. These are the states in which at least half the population is "very religious" or "not religious."
