The Table of Diversity Element African (Af) is in the eighth column, Ethnicity, on the Table of Diversity.

African is an umbrella term describing people who live in, are from, or have descendants from Africa.

"Although the precise number is unknown, there are several thousand different societies or ethnic groups in Africa. They are identified by their recognition of a common culture, language, religion, and history.

In their attempts to comprehend such a huge heterogeneous continent, scholars have often tried to divide it into culture areas that represent important geographical and ecological circumstances. Those areas reflect differences in the cultural adaptation of traditional societies to varying natural habitats. The principal regions are northern, western, west-central, eastern, and Central and Southern African; Madagascar is also included."
