The country has more than 200 African ethnic groups of which the majority are Bantu; the four largest tribes - Mongo, Luba, Kongo (all Bantu), and the Mangbetu-Azande (Hamitic) - make up about 45% of the population
Despite a wealth of fertile soil, hydroelectric power potential, and mineral resources, the Democratic Republic of the Congo (DRC) struggles with many socioeconomic problems, including high infant and maternal mortality rates, malnutrition, poor vaccination coverage, lack of access to improved water sources and sanitation, and frequent and early fertility. Ongoing conflict, mismanagement of resources, and a lack of investment have resulted in food insecurity; almost 30 percent of children under the age of 5 are malnourished. The overall coverage of basic public services – education, health, sanitation, and potable water – is very limited and piecemeal, with substantial regional and rural/urban disparities. Fertility remains high at almost 5 children per woman and is likely to remain high because of the low use of contraception and the cultural preference for larger families.
The DRC is a source and host country for refugees. Between 2012 and 2014, more than 119,000 Congolese refugees returned from the Republic of Congo to the relative stability of northwest DRC, but more than 540,000 Congolese refugees remained abroad as of year-end 2015. In addition, an estimated 3.9 million Congolese were internally displaced as of October 2017, the vast majority fleeing violence between rebel group and Congolese armed forces. Thousands of refugees have come to the DRC from neighboring countries, including Rwanda, the Central African Republic, and Burundi.
