The poll shows 60 percent of Utahns identify themselves as members of The Church of Jesus Christ of Latter-day Saints, followed by its northern neighbor, Idaho, at 24 percent. The rest of the top Mormon states fail to break into double-digit percentages with Wyoming at 9 percent; Nevada and Montana, 5 percent; Arizona, Hawaii and Alaska, 4 percent; and Washington, Colorado and Oregon, 3 percent. Other than Utah, Idaho, and Wyoming, all other U.S. states have a population of 5% or fewer Mormons.
