Digo (Chidigo) is a Bantu language spoken primarily along the East African coast between Mombasa and Tanga by the Digo people of Kenya and Tanzania. The ethnic Digo population has been estimated at around 360,000 (Mwalonya et al. 2004), the majority of whom are presumably speakers of the language. All adult speakers of Digo are bilingual in Swahili, East Africa's lingua franca.
