In Niamey, the capital, French is seen as essential for work, studies and administrative procedures. Two-thirds of residents believe that the use of French is becoming more common in the country. French became the administrative language of Rwanda in 1916. The Genocide against the Tutsi in 1994 and the victory of the Rwandan Patriotic Front were followed by a period of linguistic upheaval, with the return of refugees from Anglophone countries setting the stage for the officialisation of English in 1996 and the gradual usurpation of French as the language of education, culminating in the decision in October 2008 to make English the main language of education at higher levels, effectively relegating French to the status of third language. Nevertheless, a survey of students in Kigali found that French was known by a majority of them. French is the sole official language of Senegal. French was commonly spoken by 9.4% of Senegalese in 2002, mainly as a second language, with just 0.6% speaking it natively.

French is the main language of education in all regions of Senegal except for Kaffrine, where Arabic remains dominant, with significant Arabic-educated minorities in Kaolack (15.9% to 33.0% for French), Louga (15.8% to 22.7%) and Diourbel (15.0% to 17.2%). This phenomenon is explained by the impact of Quranic schools or Daara in those regions. French is the sole official language of Togo.
