Social organization involved groups of kin, reckoned variously matrilineally, patrilineally or bi-lineally. Certain other aspects of the Akan culture are determined patrilineally rather than matrilineally. Some societies reckon descent patrilineally for some purposes, and matrilineally for others.

Minangkabau have large corporate descent groups, but they traditionally reckon descent matrilineally. Minangkabau descendants use clan and tribal names passed down matrilineally. They live in longhouses containing several compartments occupied by matrilineally linked nuclear families. But certain rights, names or associations descend matrilineally. Females within a group are matrilineally related. Females which are matrilineally related groom each other more often than unrelated individuals. The females keep the groups cohesive and they are matrilineally related.
