Section I. Religious Demography
The U.S. government estimates the total population at 113,000 (midyear 2021). According to the 2015 census, approximately 57 percent of the population is Roman Catholic and 31 percent belongs to the Kiribati Uniting Church (until 2016 known as the Kiribati Protestant Church). Members who did not accept the name change continue as the KPC. The KPC estimates a membership of 10,000, or approximately 8 percent of the population. According to the census, 5 percent of the population belongs to the Church of Jesus Christ of Latter-day Saints (Church of Jesus Christ), but the Church states its membership exceeds 12 percent. Groups that together constitute less than 5 percent of the population include the Baha’i Faith (2 percent), Seventh-day Adventist Church (2 percent), Jehovah’s Witnesses, Assemblies of God, and Muslims. Persons with no religious affiliation account for less than 1 percent of the population. Members of the Catholic Church are concentrated in the northern islands, while Protestants constitute the majority in the southern islands.
