The U.S. government estimates the total population at 16.9 million (midyear 2020 estimate). According to Latinobarometro’s 2018 public opinion survey, approximately 92 percent of Ecuadorian respondents have a specific religious affiliation or belief: 74.8 percent identify as Catholic; 15.2 percent as evangelical; and 1.2 percent as Jehovah’s Witnesses. Approximately 1.4 percent identify as members of other specific religious groups, including Seventh-day Adventists, The Church of Jesus Christ of Latter-day Saints (Church of Jesus Christ), Jews, and other evangelical and nonevangelical Protestants. Of the remaining respondents, 0.8 identify as atheists, while 6.1 percent have no religion.

Some groups, particularly those in the Amazon region, combine indigenous beliefs with Catholicism or evangelical Protestantism. Pentecostals draw much of their membership from indigenous persons in the highland provinces. There are Jehovah’s Witnesses throughout the country, with the highest concentrations in coastal areas. Buddhist, Church of Jesus Christ, Jewish, and Muslim populations are primarily concentrated in large urban areas, particularly Quito, Guayaquil, and Cuenca. Other religious groups include Anglicans, Baha’is, Episcopalians, the Family Federation for World Peace and Unification (Unification Church), Greek Orthodox-affiliated Orthodox Church of Ecuador and Latin America, Hindus, followers of Inti (the traditional Inca sun god), and practitioners of Santeria (primarily resident Cubans). Estimates of the number of followers of these groups are not available.
