The last 40 years have seen a rapid increase in population; hence, this population is relatively young. In some African states half or more of the population is under 25 years old.
Speakers of Bantu languages (part of the Niger-Congo family) are the majority in southern, central and east Africa proper. But there are also several Nilotic groups in East Africa, and a few remaining indigenous Khoisan ('San' or 'Bushmen') and Pygmy peoples in southern and central Africa, respectively. Bantu-speaking Africans also predominate in Gabon and Equatorial Guinea, and are found in parts of southern Cameroon and southern Somalia. In the Kalahari Desert of Southern Africa, the distinct people known as the Bushmen (also "San", closely related to, but distinct from "Hottentots") have long been present. The San are physically distinct from other Africans and are the indigenous people of southern Africa. Pygmies are the pre-Bantu indigenous peoples of central Africa.
The peoples of North Africa comprise two main groups; Berber and Arabic-speaking peoples in the west, and Egyptians in the east. The Arabs who arrived in the seventh century introduced the Arabic language and Islam to North Africa. The Semitic Phoenicians, the European Greeks, Romans and Vandals settled in North Africa as well. Berbers still make up the majority in Morocco, while they are a significant minority within Algeria. They are also present in Tunisia and Libya. The Tuareg and other often-nomadic peoples are the principal inhabitants of the Saharan interior of North Africa. Nubians are a Nilo-Saharan-speaking group (though many also speak Arabic), who developed an ancient civilisation in northeast Africa.
During the past century or so, small but economically important colonies of Lebanese and Chinese have also developed in the larger coastal cities of West and East Africa, respectively.
Some Ethiopian and Eritrean groups (like the Amhara and Tigrayans, collectively known as "Habesha") speak Semitic languages. The Oromo and Somali peoples speak Cushitic languages, but some Somali clans trace their founding to legendary Arab founders. Sudan and Mauritania are divided between a mostly Arabized north and a native African south (although the "Arabs" of Sudan clearly have a predominantly native African ancestry themselves). Some areas of East Africa, particularly the island of Zanzibar and the Kenyan island of Lamu, received Arab Muslim and Southwest Asian settlers and merchants throughout the Middle Ages and in antiquity.
Beginning in the sixteenth century, Europeans such as the Portuguese and Dutch began to establish trading posts and forts along the coasts of western and southern Africa. Eventually, a large number of Dutch augmented by French Huguenots and Germans settled in what is today South Africa. Their descendants, the Afrikaners and the Coloureds, are the largest European-descended groups in Africa today. In the nineteenth century, a second phase of colonisation brought a large number of French and British settlers to Africa. The Portuguese settled mainly in Angola, but also in Mozambique. The French settled in large numbers in Algeria where they became known collectively as pieds-noirs, and on a smaller scale in other areas of North and West Africa as well as in Madagascar. The British settled chiefly in South Africa as well as the colony of Rhodesia, and in the highlands of what is now Kenya. Germans settled in what is now Tanzania and Namibia, and there is still a population of German-speaking white Namibians. Smaller numbers of European soldiers, businessmen, and officials also established themselves in administrative centers such as Nairobi and Dakar. Decolonisation during the 1960s often resulted in the mass emigration of European-descended settlers out of Africa — especially from Algeria, Angola, Kenya and Rhodesia. However, in South Africa and Namibia, the white minority remained politically dominant after independence from Europe, and a significant population of Europeans remained in these two countries even after democracy was finally instituted at the end of the Cold War. South Africa has also become the preferred destination of white Anglo-Zimbabweans, and of migrants from all over southern Africa.
European colonisation also brought sizeable groups of Asians, particularly people from the Indian subcontinent, to British colonies. Large Indian communities are found in South Africa, and smaller ones are present in Kenya, Tanzania, and some other southern and east African countries. The large Indian community in Uganda was expelled by the dictator Idi Amin in 1972, though many have since returned. The islands in the Indian Ocean are also populated primarily by people of Asian origin, often mixed with Africans and Europeans. The Malagasy people of Madagascar are a Austronesian people, but those along the coast are generally mixed with Bantu, Arab, Indian and European origins. Malay and Indian ancestries are also important components in the group of people known in South Africa as Cape Coloureds (people with origins in two or more races and continents).
