Section I. Religious Demography
The U.S. government estimates the total population at 203.5 million (July 2018 estimate). A 2012 survey by the Pew Research Center’s Forum on Religion and Public Life estimated the population to be 49.3 percent Christian and 48.8 percent Muslim, while the remaining 2 percent belong to other or no religions. Many individuals combine indigenous beliefs and practices with Islam or Christianity. A 2010 Pew report found 38 percent of the Muslim population self-identified as Sunni and 12 percent 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 groups, including Tijaniyah and Qadiriyyah. There are also Izala (Salafist) minorities and small numbers of Ahmadi Muslims. Christian groups include evangelicals, Roman Catholics, Anglicans, Pentecostals, Baptists, Anabaptists, Methodists, Presbyterians, The Church of Jesus Christ of Latter-day Saints, and Jehovah’s Witnesses. Other groups include Jews, Baha’is, and individuals who do not follow any religion.
The Hausa-Fulani and Kanuri ethnic groups are most prevalent in the predominantly Muslim northern states. Significant numbers of Christians, including some Hausa-Fulani and Kanuri, also reside in the north. Christians and Muslims reside in approximately equal numbers in the central region and southwestern states, including Lagos, where the Yoruba ethnic group, whose members include both Muslims and Christians, predominates. In the southeastern states, where the Igbo ethnic group is dominant, Christian groups, including Catholics, Anglicans, and Methodists, constitute the majority. In the Niger Delta region, where the Ogoni and Ijaw ethnic groups predominate, Christians form a substantial majority, and a very small minority of the population is Muslim. Evangelical Christian denominations are growing rapidly in the central and southern regions. Ahmadi Muslims maintain a small presence in several cities, including Lagos and Abuja.
Section II. Status of Government Respect for Religious Freedom
Abuses by Foreign Forces and Nonstate Actors
Although the U.S.-designated terrorist organization Boko Haram split into two factions in 2016, one pledging allegiance to ISIS and calling itself ISIS-WA, headed by Abu Musab al Barnawi, and another headed by Abubakar Shekau and retaining the traditional Boko Haram name, Jama’atu Ahl as-Sunnah li-Da’awati wal-Jihad (JASDJ), most residents and government officials continued to refer to both groups collectively as Boko Haram.
Boko Haram and ISIS-WA attacked population centers and religious targets in Borno State. Boko Haram also conducted limited attacks in Adamawa, while ISIS-WA attacked targets in Yobe. While Boko Haram no longer controlled as much territory as it once did, the two insurgencies nevertheless maintained the ability to stage forces in rural areas and launch attacks against civilian targets across the Northeast.
Boko Haram continued to employ suicide bombings targeting the local civilian population, including places of worship. On January 3, a Boko Haram suicide bomber attacked a Gambaru mosque, killing 14 and injuring 15. According to international news, on April 22, two suicide bombers killed three in a Bama, Borno State mosque. On May 1, twin suicide bombings in Mubi, one in a mosque and another in a market, killed at least 27 and injured more than 60 persons. According to Christian news outlets, on June 12, Boko Haram burned 22 buildings, including part of a catechetical training center in Kaya, Adamawa state. On June 16, two Boko Haram suicide bombers attacked Damboa killing 31 persons returning from Ramadan celebrations on Eid al-Fitr. On July 23, a Boko Haram suicide bomber killed eight worshippers in a mosque in Mainari.
On September 8, ISIS-WA militants, in what was reported as an effort to spread its religious ideology, launched an attack lasting several hours on Gudumbali town in Guzamala LGA of Borno State, but security forces repelled them. According to estimates from the NGO Nigeria Watch, which did not appear to differentiate between Boko Haram and ISIS-WA, 1,911 persons, including Boko Haram members, died because of the group’s activities during the year, compared with 1,749 killed in 2017.
Approximately half of the students abducted by Boko Haram from the Chibok Government Girls Secondary School in 2014 remained in captivity. In January the army reported the rescue of one girl in Borno State. On February 19, ISIS-WA abducted 111 girls from the town of Dapchi, Yobe State. According to press reports, five of the girls died during the abduction, while 105 were released on March 22 for unknown reasons. Leah Sharibu remained with the insurgents, reportedly because she refused to convert to Islam from Christianity. All other abductees were Muslims. The CAN reported more than 900 churches were destroyed by Boko Haram in the Northeast since the insurgency began in 2010.
