The fastest-growing major denomination in the study was the Church of Jesus Christ of Latter-day Saints. The Assemblies of God, a Pentecostal denomination, followed closely behind. The Mormon church grew about 19% to 4.2 million members, while the Assemblies of God grew nearly as quickly to 2.6 million.
The study was conducted by the Glenmary Research Center in Nashville, a Catholic research and social service organization that coordinates the study with analysts from several faiths. The U.S. Census Bureau does not collect information on religion.
