Bimbia, the place where Isubu is spoken, consists of three villages, namely Bona Ngombe, Bona Bile and Dikolo. These three villages are said to have been quite big in former times, but today consist only of a few houses each.
The population in Bimbia is rather mixed. Next to the Isubu people, immigrants from different places came to stay there. Some of them have become skillful fishermen, while others engage in farming. The farmers created a place called “Mbofi” or “Chop farm” which is located up the hill further inland.
