The population of DROC was estimated at 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 Lingala.

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. In 1969, it was the first independent African church admitted to the World Council of Churches.

Before independence, education was largely in the hands of religious groups. The primary school system was well-developed at independence; however, the secondary school system was limited, and higher education was almost nonexistent in most regions of the country. The principal objective of this system was to train low-level administrators and clerks. Since independence, efforts have been made to increase access to education, and secondary and higher education have been made available to many more Congolese. Despite the deterioration of the state-run educational system in recent years, about 80% of the males and 65% of females, ages 6-11, were enrolled in a mixture of state- and church-run primary schools in 1996. At higher levels of education, males greatly outnumber females. The elite continues to send their children abroad to be educated, primarily in Western Europe.
