The main population centres of Kako speakers are Batouri and Ndélélé in the East Region of Cameroon.
According to ALCAM (2012), each clan (in Kako mbó, equivalent to Beti mvog) has its own linguistic variety:[4] The Kakó Mbesámbó and Kakó Bera found in the arrondissement of Lomié and in Ngoïla (Haut-Nyong department, Eastern Region) arrived there during the French colonial era to extract rubber.
Kakó covers most of the Kadey department, notably most of fhe Batouri and Ndélélé communes and the north of Mbang (Doumé valley), while the south has Mpo speakers and Ketté commune has Gbaya speakers, who are also found in the east of Batouri and the south of Ndélélé.
Linguistic and documentary evidence support oral traditions claiming that the people speaking Kako, and thus the language, have migrated to their present positions from further east.
[3] A small group has migrated during last century in Gabon from Cameroon and has settled mainly around Batouri-Mbitam.
