Swahili, also called Kiswahili, is a Bantu language of the Niger-Congo family that developed along the East African coast through centuries of contact between Bantu-speaking communities and Arabic-speaking traders, absorbing a substantial layer of Arabic vocabulary in the process. It functions today as a lingua franca across Tanzania, Kenya, Uganda and neighboring countries and as an official language of the African Union, and, unusually for a Bantu language, is the primary language of a very large population who use it as a learned second rather than first language, which is the source of the wide disagreement over its total speaker numbers.

Facts

Disputed

Speaker Count

16,000,000 1

Sources diverge sharply on what is being counted. Ethnologues figure of roughly 16 million counts first-language speakers only; other widely cited estimates put total speakers, overwhelmingly second-language users of Swahili as an East African lingua franca, at well over 100 million, with some estimates as high as 200 million. There is no real dispute that Swahili has vastly more second-language than first-language speakers, only over how to weight that population in a single headline number.
