Africa has a third of the world’s languages.

With more than 2,000 distinct languages, Africa has a third of the world’s languages with less than a seventh of the world’s population. By comparison, Europe, which has about an eighth of the world’s population, has only about 300 languages.

Africa’s linguistic diversity can even be found among individual Africans. For instance, a study of 100 inhabitants in a city in western Uganda found that the average speaker knows 4.34 actual languages.

So why is this anyway? To help explain diversity, linguists borrow tools from evolutionary biologists:  linguists explore the relationships between distinct languages in the same way evolutionary biologists explore family relationships and speciation of living things. Given the parallels in these two fields, it’s no coincidence that Africa, the place of highest genetic diversity, contains rich linguistic diversity as well.

The origins of high genetic diversity

“Pretty much every study that’s ever been done involving looking at genetic variation in Africans compared to non-Africans always shows more diversity in Africans,” University of Pennsylvania geneticist Sarah Tishkoff tells the Monitor.

Population genetics theory predicts that the highest level of diversity exists at the source of the population’s origin. For humans, that is Africa.

African languages are grouped into four main “families”:

  • Afro-Asiatic
  • Nilo-Saharan
  • Khoisan
  • Niger-Congo

The majority of countries have retained the official language of the colonizer. Very few of the continent’s indigenous languages have an official status.

The Afro-Asiatic Family

There are 353 languages in this family, totaling 340 million speakers. However, the Afro-Asiatic languages are not exclusively African. This language family also extends to the Arabian Peninsula and covers only the northern part of West Africa.

Berbere, the original language of the inhabitants of North Africa, is part of this language group as well as Arabic, which is the language with the most speakers in Africa.

The Nilo-Saharan Family

The Nilo-Saharan family consists of 197 languages with 35 million speakers. These languages cover some of the upper part of the Nile basin and highlands in East Africa.

There are twelve groups of languages that compose this language family. But, only two are located in West Africa: the Songhai (Mali, Niger, Burkina, and Benin) and Kanuri (Niger, Nigeria, Cameroon and Chad).

The Khoisan Family

This language family is the smallest African language family. It is made up of 22 languages and 360,000 speakers.

These languages are located in Namibia and extend to Angola, Botswana and South Africa. Historically, the Khoisan languages were spoken in southern and eastern Africa. They were slowly replaced by many of the Bantu languages and then European languages.

The Niger-Congo Family

The Niger-Congo family has nearly 1500 languages, making it the largest language family in the world. It makes up 71% of African languages and 22% of the world’s languages.

It covers most of the West African countries and the vast majority of the population of the region. The Bantu languages are in this family, which cover almost all of sub-equatorial Africa. Kiswhalili (aka Swahili) also belongs to this language group.

Many experts believe that the original home of the Bantu languages is located south of the Benue (along the Cameroon and Nigeria border). 4000 years ago, the Bantus began a long relocation to Central Africa, driven by the aridity of the climate and the development of agriculture.

This colonization took nearly three millennia. Bantus reached the southern continent in the sixteenth century.

The many similarities between the Bantu languages ​​and their remarkable geographic expansion in a specific language area are often distinguished from the rest of the Niger-Congo family.


Africa is an extremely diverse continent. Anyone looking to travel or expand their global business there should fully research the specific country or region they are interested in to understand the languages and cultures that exist.

This vast continent presents many opportunities for African companies, as well as global companies looking to expand into the African marketplace.
