The country has an area of 905,000 square miles and a population of 68.7 million. The population is approximately 50 percent Roman Catholic, 20 percent mainline Protestant, 9 percent Kimbanguist, and 9 percent Muslim. Other religious groups represented in much smaller numbers include Jehovah's Witnesses, the Church of Jesus Christ of Latter-day Saints (Mormons), and Orthodox Christians. The remainder generally practices indigenous religious beliefs.
Most religious groups are scattered throughout the country and are widely represented in cities and large towns. Muslims are mainly concentrated in the provinces of Maniema, Orientale, and Kinshasa. Members of the ethnically based spiritual and political movement Bundu dia Kongo (BDK) reside predominantly in Bas-Congo Province; BDK has never attempted to gain official recognition as a religious association.
