The village, village division, and natal group are the most basic social units in Kanbi society. In leading Kanbi villages, the Kanbi are descendants of one man (a founding ancestor); in some villages, a minority lineage that predates the founding ancestor may also exist. In large villages, the descendants of a common ancestor build a compound ( chok or khadaki ) together. In wealthy villages, all members of the compound are agnatically related. At one time, these compounds may have served as home to several generations. By 1972, they housed little more than joint families of two generations' depth. Secession (and lineal segmentation) may take place; however, this is a rare occurrence. Compounds of this sort are not usually found in smaller Kanbi villages. The bhayat (small division consisting of four or five generations) also figures prominently in Kanbi social structure. It is the closest group of mutual cooperation outside the family. Patrilineal descent is the Kanbi norm.
