Italy - Religions
In 1998, the overwhelming majority (85%) of native-born Italian citizens professed the Roman Catholic faith. Roman Catholicism, affirmed as the state religion under the Lateran Treaty of 1929, lost that distinction under a concordat with the Vatican ratified in 1985. However, the Catholic Church continues to hold a privileged status with the state. Jehovah's Witnesses form the second-largest denomination among native-born Italian citizens, with about 400,000 adherents. However, if immigrants are counted, the second-largest religion is Islam, with an estimated one million followers. About 100,000 people are Scientologists, 60,000 are Buddhists, 30,000 are Waldensians (a Calvinist sect), 30,000 are Jewish, and 20,000 are Mormons. The Orthodox and Protestant Churches have small communities. Hinduism is also represented.
