Senegal is a multilingual country – Ethnologue lists 36 languages. Of those, Wolof is the most widely spoken.
French, which was inherited from the colonial era, is the official language of Senegal. It is used by the administration and understood by about 15–20% of all males and about 1–2% of all women. Senegal is a member State of the OIF (Organisation internationale de la Francophonie). A Senegalese, Abdou Diouf, has held the position of Executive Secretary of the OIC between 2003 and 2014.
Mande languages spoken include Soninke, and Mandinka. Jola (Diola) is a main language in the Casamance region. The Guinea Creole dialect, based on Portuguese is also spoken in that region. In 2008 Senegal, due to its historical connections to Portuguese colonisation in Casamance, was admitted as Associate Observer in the CPLP (Community of Portuguese Language Countries).
A report for the High Council of Francophonie in Paris stated in 1986 that in Senegal, 60,000 people spoke French as a first language and 700,000 spoke French as a second language. The total population of Senegal at the time was 6.5 million.
