The U.S. government estimates the population at 101.8 million (midyear 2019 estimate). Most experts and media sources state that approximately 90 percent of the population is Sunni Muslim and approximately 10 percent is Christian (estimates range from 5 to 15 percent). Approximately 90 percent of Christians belong to the Coptic Orthodox Church, according to Christian leaders.

Other Christian communities together constitute less than 2 percent of the population and include Anglican/Episcopalian and other Protestant denominations, Armenian Apostolic, Catholic (Armenian, Chaldean, Melkite, Maronite, Latin, and Syrian), and Orthodox (Greek and Syrian) Churches. The Protestant community includes Apostolic Grace, Apostolic, Assemblies of God, Baptists, Brethren, Christian Model Church (Al-Mithaal Al-Masihi), Church of Christ, Faith (Al-Eyman), Gospel Missionary (Al-Kiraaza bil Ingil), Grace (An-Ni’ma), Independent Apostolic, Message Church of Holland (Ar-Risaala), Open Brethren, Pentecostal, Presbyterian, Revival of Holiness (Nahdat al-Qadaasa), and Seventh-day Adventist. Jehovah’s Witnesses account for 1,000-1,500 persons, according to media estimates, and there are also an estimated 150 members of The Church of Jesus Christ of Latter-day Saints (Church of Jesus Christ), the vast majority of whom are expatriates. Christians reside throughout the country, although the percentage of Christians is higher in Upper Egypt and in some sections of Cairo and Alexandria, according to religious and civil society groups.

Scholars estimate that Shia Muslims comprise approximately 1 percent of the population. Baha’i representatives estimate the size of the community to be between 1,000 and 2,000. There are very small numbers of Dawoodi Bohra Muslims, Ahmadi Muslims, and expatriate members of various groups.

According to a local Jewish nongovernmental organization (NGO), there are six to 10 Jews. There are no reliable estimates of the number of atheists.

The U.S. government estimates the total population at 81.6 million (midyear 2019 estimate). According to the government, 99 percent of the population is Muslim, approximately 77.5 percent of which is Hanafi Sunni. Representatives of other religious groups estimate their members represent 0.2 percent of the population, while the most recent public opinion surveys published in January by Turkish research firm KONDA suggest approximately 3 percent of the population self-identifies as atheist and 2 percent as nonbelievers.

Leaders of Alevi foundations estimate Alevis comprise 25 to 31 percent of the population; Pew Research Center reporting indicates 5 percent of Muslims state they are Alevis. The Shia Jafari community estimates its members make up 4 percent of the population.

Non-Muslim religious groups are mostly concentrated in Istanbul and other large cities, as well as in the southeast. Exact figures are not available; however, these groups self-report approximately 90,000 Armenian Apostolic Orthodox Christians (including migrants from Armenia); 25,000 Roman Catholics (including migrants from Africa and the Philippines); and 16,000 Jews. There are also approximately 25,000 Syrian Orthodox Christians (also known as Syriacs); 15,000 Russian Orthodox Christians (mostly immigrants from Russia who hold residence permits); and 10,000 Baha’is.

Estimates of other groups include fewer than 1,000 Yezidis; 5,000 Jehovah’s Witnesses; 7,000-10,000 members of Protestant denominations; fewer than 3,000 Chaldean Christians; and up to 2,500 Greek Orthodox Christians. There also are small, undetermined numbers of Bulgarian Orthodox, Nestorian, Georgian Orthodox, Ukrainian Orthodox, Syriac Catholic, Armenian Catholic, and Maronite Christians. The Church of Jesus Christ of Latter-day Saints (Church of Jesus Christ) estimates its membership at 300 individuals.
