Mormons on the Rise

The number of Mormons are on the rise in the U.S. and the number of mainline Protestants and Catholics is falling. That's according to the 2012 Religious Congregations and Membership Study. In the largest county in the U.S. Catholics fell 7% and Mormons rose by 55%. In fact, the Church of Jesus Christ of Latter-day Saints is the fastest-growing religious group in the U.S. While 8 of 10 Americans call themselves Christians, only half have an affiliation with a local church.
