Clans
614
Presence of unilineal kin groups of traditional, but not actually traceable, common descent; number and distribution; type of affiliation (e.g., matrilineal, patrilineal); regulation of marriage by clan membership (e.g., exogamy, agamy, endogamy); distinguishing characteristics (e.g., names, insignia, totemism, food taboos); origin and traditions; organization; headship and succession; prerogatives and obligations of members; unilineal kin groups intermediate between clans and phratries; relations between clans, etc. American anthropologists have sometimes used the term “sib” instead of clan to describe this type of kinship group.
The term was changed from "Sibs" to "Clans" and the scope note was revised in 2005.
