They still engaged in hunter and considered to be hunters by themselves and by the neighboring farmers. in the Souanke District in the western part of the Region, 664 Baka lived in 15 settlements. The data on birth place suggest that the Bake in the area originally had a close relationship with the Baka in Cameroon. Some Baka informants said that there were a totoal of 22 Baka settlements in Sembe District in the center of the region. In the Mokeko District in the eastern part, the author confirmed 25 settlements and another 11 settlements were counted by the local informants. The inhabitants of these settlements included all five linguistic groups. Several cases of fission and fusion of Baka settlements with farmer villages in Souanke demonstrate the social-economic relationships between the two groups..."
