Section I. Religious Demography
The U.S. government estimates the total population at 11 million (midyear 2021). The 2020 Pew-Templeton Global Religious Futures Project report estimated that Christians make up 60.5 percent of the population; followers of indigenous (animist) religions, 32.9 percent; and Muslims, 6.2 percent. Other religious groups with small populations include the Baha’i Faith, Buddhism, Hinduism, and Judaism. The country’s massive population displacement resulting from nearly a decade of conflict, as well as a large population of pastoralists who regularly migrate within and between countries, make it difficult to accurately estimate the overall population and its religious demography.
According to the South Sudan Council of Churches and the government Bureau of Religious Affairs, the principal Christian denominations are Roman Catholic, Episcopal, Presbyterian, Pentecostal, Sudan Interior, Presbyterian Evangelical, and African Inland Churches. Smaller congregations of Eritrean Orthodox, Ethiopian Orthodox, Coptic Orthodox, Greek Orthodox, The Church of Jesus Christ of Latter-day Saints, Seventh-day Adventists, and Jehovah’s Witnesses are also present. Adherents of indigenous religious traditions reside throughout the country and practice their indigenous religions alongside Christianity and Islam.
