Details of Africans (Negro people in sub-Saharan Africa)

Africans generally refer to Negro people in sub-Saharan Africa. Their languages are divided into four categories: Khoisan, Niger-Congo, Bantu and Nile-Sahara. Because people in sub-Saharan Africa are mostly black, Africans often refer to black people. Sometimes Africans include Arabs in North Africa and Caucasians in South Africa.
