The U.S. government estimates the total population at 15.4 million (July 2013 estimate). A 2012 survey by the Ecuadorian National Institute of Statistics and Census indicates 80 percent of the population is Roman Catholic, 11 percent is evangelical Christian, and 6 percent belongs to other religious groups including Islam, Hinduism, and indigenous and African faiths. Smaller religious groups include The Church of Jesus Christ of Latter-day Saints (Mormons), Jehovah’s Witnesses, Buddhists, Jews, spiritualists, Anglicans, Episcopalians, Bahais, Lutherans, members of the Eastern Orthodox Church, Presbyterians, members of the Unification Church, and followers of Inti (the traditional Inca sun god). Some groups combine indigenous beliefs with Catholicism. Pentecostals draw much of their membership from indigenous people in the highland provinces. Hundreds of evangelical churches exist, many of which are not affiliated with a particular denomination. These groups include Avant Ministries, the Christian and Missionary Alliance, and Hoy Cristo Jesus Bendice (Today Jesus Christ Blesses). There are also practitioners of Santeria, primarily resident Cubans.
