Demographics
Main article: Demographics of the Democratic Republic of the Congo
The population was estimated at 56.6 million in 2003, growing quicky from 46.7 million in 1997. As many as 250 ethnic groups have been distinguished and named. The most numerous people are the Kongo, Luba, and Mongo. Although 700 local languages and dialects are spoken, the linguistic variety is bridged both by the use of French and the intermediary languages Kikongo, Tshiluba, Swahili, and Ligala.
About 80% of the Congolese population are Christian, predominantly Roman Catholic. Most of the non-Christians adhere to either traditional religions or syncretic sects. Traditional religions embody such concepts as monotheism, animism, vitalism, spirit and ancestor worship, witchcraft, and sorcery and vary widely among ethnic groups; none is formalized. The syncretic sects often merge Christianity with traditional beliefs and rituals. The most popular of these sects, Kimbanguism, was seen as a threat to the colonial regime and was banned by the Belgians. Kimbanguism, officially "the church of Christ on Earth by the prophet Simon Kimbangu," now has about 3 million members, primarily among the Bakongo of Bas-Congo and Kinshasa.
