Americans continue to be geographically segregated by religion. Protestants dominate in the South, while Catholics are most common in the Northeast and mid-Atlantic, with some representation in the Midwest. Americans with no formal religious identity are most likely to be found in the West and in New England. Two smaller religious groups are also geographically concentrated: Mormons are a major population factor in Utah and Idaho, and Jews tend to be disproportionately located on the East Coast. CONT.
