A decennial census of U.S. religions in America was released Tuesday by the Association of Statisticians of American Religious Bodies (ASARB). The results show a dramatic increase in the number of Latter-day Saints, or Mormons, and Muslims, a modest increase in the number of evangelical Protestants, and a drop in the number of Catholics and mainline Protestants.
Muslims saw the greatest growth rate among the five main religious groups studied. Their numbers increased by 66.7 percent in the 2010 census from a decade earlier. Latter-day Saints saw the next highest growth at 45.5 percent, followed by evangelical Protestants at only 1.7 percent. The number of Catholics decreased by five percent and the number of mainline Protestants decreased by 12.8 percent.
