The U.S. government estimates the total population at 210.3 million (midyear 2019 estimate). According to a 2016 Datafolha survey, 50 percent of the population identifies as Catholic, compared with 60 percent in 2014. During the same period, the proportion of atheists increased from 6 percent to 14 percent, and the proportion of evangelical Christians increased from 24 percent to 31 percent. According to the 2010 census, 65 percent of the population is Catholic, 22 percent Protestant, 8 percent irreligious (including atheists, agnostics, and deists), and 2 percent Spiritist. Adherents of other Christian groups, including Jehovah’s Witnesses, the Church of Jesus Christ, Seventh-day Adventists, as well as followers of non-Christian religions, including Buddhists, Jews, Muslims, Hindus, and Afro-Brazilian and syncretic religious groups such as Candomble and Umbanda, make up a combined 3 percent of the population. According to the census, there are 588,797 practitioners of Candomble, Umbanda, and other Afro-Brazilian religions, and some Christians also practice Candomble and Umbanda. According to a nonrepresentative 2017 survey of 1,000 persons older than age 18 by researchers at the University of Sao Paulo, 44 percent of Brazilians consider themselves followers of more than one religion.

According to the 2010 census, approximately 35,200 Muslims live in the country, while the Federation of Muslim Associations of Brazil estimates the number to be 1.2 to 1.5 million. The largest communities reside in Sao Paulo, Rio de Janeiro, Curitiba, and Foz do Iguazu, as well as in smaller cities in the states of Parana and Rio Grande do Sul.

According to the Jewish Confederation of Brazil, there are approximately 125,000 Jews. The two largest concentrations are 65,000 in Sao Paulo State and 29,000 in Rio de Janeiro State.

The U.S. government estimates the total population at 48.6 million (midyear 2019 estimate). The Roman Catholic Church estimates 75 percent of the population is Catholic. According to a 2017 survey by the NGO Latinobarometer, 73 percent of the population is Catholic, 14 percent Protestant, and 11 percent atheist or agnostic.

The Colombian Confederation of Jewish Communities (CJCC) estimates there are approximately 5,500 Jews. There is also a small population of adherents to animism and various syncretic beliefs.

Some religious groups are concentrated in certain geographical regions. Most of those who blend Catholicism with elements of African animism are Afro-Colombians and reside on the Pacific coast. Most Jews reside in major cities (approximately 70 percent in Bogota), most Muslims on the Caribbean coast, and most adherents of indigenous animistic religions in remote rural areas. A small Taoist community is located in a mountainous region of Santander Department.

The U.S. government estimates the total population at 7.2 million (midyear 2019 estimate). According to SAR government statistics, there are more than one million followers of Taoism and approximately one million followers of Buddhism; 500,000 Protestants; 389,000 Roman Catholics (The Catholic Diocese of Hong Kong recognizes the pope and maintains links to the Vatican.); 100,000 Hindus; and 12,000 Sikhs. According to the World Jewish Congress, approximately 2,500 Jews live in Hong Kong.

SAR government statistics estimate there are approximately 300,000 Muslims. Small communities of Baha’is and Zoroastrians also reside in the SAR. Confucianism is widespread, and in some cases, elements of Confucianism are practiced in conjunction with other belief systems. The Falun Gong estimates there are approximately 500 Falun Gong practitioners.

There are dozens of Protestant denominations, including Anglican, Baptist, Christian and Missionary Alliance, the Church of Christ in China, Lutheran, Methodist, Pentecostal, and Seventh-day Adventists.

The U.S. government estimates the total population at 208.7 million (midyear 2019 estimate). While there are no official indicators of religious affiliation in the country, most analysts say it is roughly evenly divided between Muslims and Christians, while approximately 2 percent belong to other or no religious groups. Many individuals syncretize indigenous animism with Islam or Christianity.

A 2010 Pew report found 38 percent of the Muslim population self-identifies as Sunni, the vast majority of whom belong to the Maliki school of jurisprudence, though a sizable minority follows Shafi’i fiqh. The same study found 12 percent of Muslims in the country self-identify as Shia, with the remainder declining to answer or identifying as “something else” (5 percent) or “just a Muslim” (42 percent). Included among the Sunnis are several Sufi brotherhoods, including Tijaniyah, Qadiriyyah, and Mouride. There are also Izala (Salafist) minorities and small numbers of Ahmadi and Kalo Kato (Quraniyoon) Muslims. A 2011 Pew report found among Christians, roughly one quarter are Roman Catholic and three quarters Protestant, with small numbers of Orthodox or other Christian denominations. Among Protestant groups, the Anglican, Baptist, and Presbyterian churches maintain the largest populations, while evangelicals, Pentecostals, Anabaptists (EYN Church of the Brethren), Methodists, Seventh-day Adventists, New Apostolics, The Church of Jesus Christ of Latter-day Saints, and Jehovah’s Witnesses report tens of thousands of adherents each. Other communities include Baha’is, Jews (including significant numbers of Judaic-oriented groups), Hindus, Sikhs, Buddhists, animists, and individuals who do not follow any religion.

The Hausa, Fulani, and Kanuri ethnic groups are most prevalent in the predominantly Muslim North West and North East states. Significant numbers of Christians, including some Hausa, Fulani, and Kanuri, also reside in the North East and North West. Christians and Muslims reside in approximately equal numbers in the North Central and South West states, including Lagos, where the Yoruba ethnic group – whose members include both Muslims and Christians – predominates. In the South East and South states, where the Igbo ethnic group is dominant, Christian groups, including Catholics, Anglicans, and Methodists, constitute the majority. In the Niger Delta region, where ethnic groups include Ijaw, Igbo, Ogoni, Efik, Ibibio, and Uhrobo among others, Christians form a substantial majority; a small but growing minority of the population is Muslim. Evangelical Christian denominations are growing rapidly in the North Central and South East, South, and South West regions. Ahmadi Muslims maintain a small presence in several cities, including Lagos and Abuja. The Shia Muslim presence is heavily concentrated in the North West states of Kaduna, Katsina, Sokoto, Zamfara, and Kano.

The U.S. government estimates the total population at 107.5 million (midyear 2019 estimate). According to the 2015 census (the most recent) conducted by the Philippine Statistics Authority (PSA), 79.5 percent of the population is Roman Catholic and 9 percent belong to other Christian groups, including Seventh-day Adventists, United Church of Christ, United Methodists, Episcopal Church in the Philippines, Bible Baptist Church, other Protestant churches, Jehovah’s Witnesses, and The Church of Jesus Christ of Latter-day Saints. Other Christian groups include locally established churches such as the Iglesia ni Cristo (Church of Christ), Philippine Independent Church (Aglipayan), Members Church of God International, the Kingdom of Jesus Christ, and the Name Above Every Name. Approximately 6 percent of the population is Muslim, according to the PSA; the NCMF estimates that 10 to 11 percent of the population is Muslim. The NCMF attributes the higher estimate to a number of factors: the reluctance of Muslims to officially register with the civil registrar office or to participate in the formal survey, the community’s transience due to internal movement for work, and the government’s failure to survey Muslim areas and communities thoroughly. According to the PSA, approximately 4 percent of those surveyed in the 2015 census did not report a religious affiliation or belong to other groups, such as animism or indigenous syncretic faiths.

A majority of Muslims are members of various ethnic minority groups and reside in Mindanao and nearby islands in the south. Although most are practitioners of Sunni Islam, a small minority of Shia Muslims live in the provinces of Lanao del Sur and Zamboanga del Sur on Mindanao. An increasing number of Muslims are migrating to the urban centers of Manila, Baguio, Dumaguete, Cagayan de Oro, Iligan, Cotabato, and Davao, a trend that accelerated after the May-October 2017 siege of Marawi in which local residents fled to other provinces for their security.
