Language provides the most convenient means of categorising the Adamawa's ethnic groups. The greatest number of peoples speak various Southern Bantoid languages. These Bantoid peoples primarily occupy the province's western third, in the Faro and Deo and the Mayo-Banyo divisions. The Ndoro are the northernmost, living on the Nigerian border on the upper Mayo Deo. To their south lie the Nyem-Nyem, called Suga by the Mbum, in the northern third of Mayo-Banyo division and along the west bank of the Meng River. The Vute live south of them on the Nigerian border and in a second population centre on the southwestern bank of the Mbarkaou Reservoir. The Mambila inhabit the southwestern border, and the Konja lie inland from them along the Banyo-Bankim road. The Tikar are at the province's southwestern corner, with territories extending into the neighbouring provinces.
