Matrilocal

In social anthropology, matrilocal residence or matrilocality (also uxorilocal residence or uxorilocality) is the societal system in which a married couple resides with or near the wife's parents. Thus, the female offspring of a mother remain living in (or near) the mother's house, thereby forming large clan-families, typically consisting of three or four generations living in the same place.

Frequently, visiting marriage is being practiced, meaning that husband and wife are living apart in their separate families, seeing each other in their spare time. The children of such marriages are raised by the mother's extended matrilineal clan. The father does not have a significant role in the upbringing of his own children; he does, however, in that of his sisters' children (his nieces and nephews). In direct consequence, property is inherited from generation to generation, and, over all, remains largely undivided.

Matrilocal residence is found most often in horticultural societies.

Examples of matrilocal societies include the people of Ngazidja in the Comoros, the Ancient Pueblo Peoples of Chaco Canyon, the Nair community in Kerala in South India, the Moso of Yunnan and Sichuan in southwestern China, the Siraya of Taiwan, and the Minangkabau of western Sumatra. Among indigenous people of the Amazon basin this residence pattern is often associated with the customary practice of brideservice, as seen among the Urarina of northeastern Peru. In contemporary mainland China, matrilocal residence has been encouraged by the government in an attempt to counter the problem of unbalanced male-majority sex ratios caused by the abortion, infanticide and abandonment of girls. Because girls traditionally marry out in virilocal marriage (living with or near the husband's parents) they have been seen as "mouths from another family" or as a waste of resources to raise. During the Song Dynasty in medieval China, matrilocal marriage became common for wealthy non-aristocratic families.
