Demographics

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.[citation needed]

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).

Languages

By most estimates, Africa contains well over a thousand languages, some have estimated it to be over two thousand languages (most of African rather than European origin). Africa is the most polyglot continent in the world; it is not rare to find individuals there who fluently speak not only several African languages, but one or two European ones as well. There are four major language families native to Africa.

The Afro-Asiatic languages are a language family of about 240 languages and 285 million people widespread throughout East Africa, North Africa, the Sahel, and Southwest Asia.
The Nilo-Saharan language family consists of more than a hundred languages spoken by 30 million people. Nilo-Saharan languages are mainly spoken in Chad, Ethiopia, Kenya, Sudan, Uganda, and northern Tanzania.
The Niger-Congo language family covers much of Sub-Saharan Africa and is probably the largest language family in the world in terms of different languages. A substantial number of them are the Bantu languages spoken in much of sub-Saharan Africa.
The Khoisan languages number about 50 and are spoken in Southern Africa by approximately 120 000 people. Many of the Khoisan languages are endangered. The Khoi and San peoples are considered the original inhabitants of this part of Africa.
Following colonialism, nearly all African countries adopted official languages that originated outside the continent, although several countries nowadays also use various languages of native origin (such as Swahili) as their official language. In numerous countries, English and French are used for communication in the public sphere such as government, commerce, education and the media. Arabic, Portuguese, Afrikaans and Malagasy are other examples of originally non-African languages that are used by millions of Africans today, both in the public and private spheres.

Africa

Africa is the oldest inhabited territory on earth, with the human species originating from the continent. During the middle of the twentieth century, anthropologists discovered many fossils and evidence of human occupation perhaps as early as 7 million years ago. Fossil remains of several species of early apelike humans thought to have evolved into modern man, such as Australopithecus afarensis (radiometrically dated to c. 3.9-3.0 million years BC),[7] Paranthropus boisei (c. 2.3-1.4 million BC) and Homo ergaster (c. 600,000-1.9 million BC) have been discovered.

The Ishango bone, dated to about 25,000 years ago, shows tallies in mathematical notation. Throughout humanity's prehistory, Africa (like all other continents) had no nation states, and was instead inhabited by groups of hunter-gatherers such as the Khoi and San.
Although there are absolutely no records, theorists think that by 130,000 BC the bulk of Africa's populations inhabited the Sahara, which was at that time a fertile valley criss-crossed by rivers. Artful incisions in African ocher made around this time are the oldest images in the world. In 70,000 BC Africa suffered an extinction of 30% of its wildlife species.[citation needed] According to this theory, in 30,000 BC the world entered the last major ice age. As a result of this, the Sahara Desert reached up to the Ethiopian Highlands. Central Africa's mountain ranges were covered by ice flow. The River Nile, north of Khartoum, disappeared[citation needed].

At the end of the ice age guessed to have been around 10,500 BC, the Sahara had become a green fertile valley again, and its African populations returned from the interior and coastal highlands in Sub-Saharan Africa. However, the warming and drying climate meant that by 5000 BC the Sahara region was becoming increasingly drier. The population trekked out of the Sahara region towards the Nile Valley below the Second Cataract where they made permanent or semi-permanent settlements. A major climatic recession occurred, lessening the heavy and persistent rains in Central and Eastern Africa. Since then dry conditions have prevailed in Eastern Africa, especially in Ethiopia in the last 200 years.

The domestication of cattle in Africa precedes agriculture and seems to have existed alongside hunter-gathering cultures. It is speculated that by 6000 BC cattle were already domesticated in North Africa . In the Sahara-Nile complex, people domesticated many animals including the pack ass, and a small screw horned goat which was common from Algeria to Nubia.

Agriculturally, the first cases of domestication of plants for agricultural purposes occurred in the Sahel region circa 5000 BC, when sorghum and African rice began to be cultivated. Around this time, and in the same region, the small guinea fowl became domesticated.

According to the Oxford Atlas of World History, in the year 4000 BC the climate of the Sahara started to become drier at an exceedingly fast pace. This climate change caused lakes and rivers to shrink rather significantly and caused increasing desertification. This, in turn, decreased the amount of land conducive to settlements and helped to cause migrations of farming communities to the more tropical climate of West Africa.

By 3000 BC agriculture arose independently in both the tropical portions of West Africa, where African yams and oil palms were domesticated, and in Ethiopia, where coffee and teff became domesticated. No animals were independently domesticated in these regions, although domestication did spread there from the Sahel and Nile regions. Agricultural crops were also adopted from other regions around this time as pearl millet, cowpea, groundnut, cotton, watermelon and bottle gourds began to be grown agriculturally in both West Africa and the Sahel Region while finger millet, peas, lentil and flax took hold in Ethiopia.

The international phenomenon known as the Beaker culture began to affect western North Africa. Named for the distinctively shaped ceramics found in graves, the Beaker culture is associated with the emergence of a warrior mentality. North African rock art of this period depicts animals but also places a new emphasis on the human figure, equipped with weapons and adornments. People from the Great Lakes Region of Africa settled along the eastern shore of the Mediterranean Sea to become the proto-Canaanites who dominated the lowlands between the Jordan River, the Mediterranean and the Sinai Desert.

By the 1st millennium BC ironworking had been introduced in Northern Africa and quickly began spreading across the Sahara into the northern parts of sub-saharan Africa[17] and by 500 BC metalworking began to become commonplace in West Africa, possibly after being introduced by the Carthaginians. Ironworking was fully established by roughly 500 BC in areas of East and West Africa, though other regions didn't begin ironworking until the early centuries AD. Some copper objects from Egypt, North Africa, Nubia and Ethiopia have been excavated in West Africa dating from around 500 BC time period, suggesting that trade networks had been established by this time
