The U.S. government estimates the total population at 87.3 million (midyear 2019 estimate). The Pew Research Center estimates 95.8 percent of the population is Christian, 1.5 percent Muslim, and 1.8 percent report no religious affiliation (2010 estimate). Of Christians, 48.1 percent are Protestant, including evangelical Christians and the Church of Jesus Christ on Earth through the Prophet Simon Kimbangu (Kimbanguist), and 47.3 percent Catholic. Other Christian groups include the Jehovah’s Witnesses, The Church of Jesus Christ of Latter-day Saints, and the Greek Orthodox Church. There are small communities of Hindus, Jews, Buddhists, Baha’is, and followers of indigenous religious beliefs. Muslim leaders estimate their community to comprise approximately 5 percent of the population.

A significant portion of the population combines traditional beliefs and practices with Christianity or other religious beliefs.

Illegal armed groups operating in the provinces of North Kivu and Ituri in the eastern part of the country occasionally targeted church leaders. Local media reported that on June 5, armed militia members kidnapped Father Luc Adelar Alecho, a priest and the administrator of the Catholic parish of Marie Reine de Jiba, in Ituri Province’s Welendu Ptisi Sector. The reports stated that the militants reproached him for his homilies urging his congregation to reject armed groups before letting him go.

Some religious leaders reported continued tensions between Christian and Muslim communities in the north. Local leaders expressed concerns that the nomadic Muslim Mbororo herder population was part of an “Islamic invasion” of the country. Sporadic violence between local communities and the Mbororo in Upper and Lower Uele Provinces throughout the year resulted in several deaths. In addition to religious differences, observers stated there were also economic and political concerns linked to the conflict and for that reason it was difficult to categorize these acts as solely based on religious belief.

In April ISIS claimed responsibility for attacks against a government military base that were carried out by the Allied Democratic Forces (ADF), an armed group long-operating in North Kivu Province that proclaimed allegiance to ISIS in 2017 and was publicly recognized by ISIS as an affiliate in late 2018. In conjunction with the April claim of responsibility, ISIS announced the establishment of a new wilayat (province), ISIS–Central Africa. According to civil society sources in the eastern part of the country, these statements highlighted ADF’s desire to promote a strict brand of Islam in the overwhelmingly Christian region of the Great Lakes. Local Christian and Muslim leaders, with vocal support from the government, condemned ADF’s actions.

Leaders of the Jehovah’s Witnesses reported generally positive relations with individuals from other religious groups but noted that 27 cases of assault on or suspected killings of Jehovah’s Witnesses dating from as early as 2015 continued to languish in the court system or were never sent to court for criminal prosecution after the arrests of suspects. They also reported five assaults during the year that they stated were due to their religious beliefs in rural areas of Kwilu, South Kivu, and Sankuru Provinces.

Muslim leaders said that Christian groups sometimes failed to include them in intercommunal dialogues.

During the year, the Anglican Church reported that it was attempting to leave the Church of Christ in Congo, (ECC) a union of more than 70 Protestant denominations, in order to have the ability to act more independently.

The U.S. government estimates the total population at 42.2 million (midyear 2019 estimate). According to the most recent census, conducted in 2014, 82 percent of the population is Christian. The largest Christian group is Roman Catholic with 39 percent; 32 percent is Anglican, and 11 percent Pentecostal Christian. According to official government estimates, Muslims constitute 14 percent of the population. The UMSC estimates Muslims (primarily Sunni) are closer to 20 percent of the population. Other religious groups, which collectively constitute less than 5 percent of the population, include Seventh-day Adventists, adherents of indigenous beliefs, Baptists, Orthodox Christians, Hindus, Jews, and those with no religious affiliation.

According to the Indian Association in Uganda, the largest non-African ethnic population is of Indian origin or descent, most of whom are Hindu. The Jewish community of approximately 2,000 members is mainly concentrated in Mbale Town, in the eastern region of the country. Generally, religious groups are dispersed evenly across the country, although there are concentrations of Muslims in eastern and northern parts of the country.

On October 23, media reported Ivan Samuel Ssebadduka, who referred to himself as a monotheistic Christian, petitioned the Constitutional Court seeking to prevent all Muslims from using the name Allah when referring to God. The case was ongoing at year’s end.
