Salt Lake County Is Becoming Less Mormon — Utah County Is Headed In The Other Direction

New LDS Church data show a growing divide in the religious makeup of Utah’s two most populous counties, a demographic shift that has sweeping political and cultural ramifications. The 3 million-strong Beehive State, as a whole, remains roughly 62.8 percent Mormon. But Salt Lake County, home to the headquarters of the The Church of Jesus Christ of Latter-day Saints, continues to see its portion of residents on LDS membership rolls decline.
