In social anthropology, patrilocal residence or patrilocality, also known as virilocal residence or virilocality, are terms referring to the social system in which a married couple resides with or near the husband's parents. The concept of location may extend to a larger area such as a village, town or clan territory. The practice has been found in around 70 percent of the world's modern human cultures that have been described ethnographically. Archaeological evidence for patrilocality has also been found among Neanderthal remains in Spain and for ancient hominids in Africa.
In a patrilocal society, when a man marries, his wife joins him in his father's home or compound, where they raise their children. These children will follow the same pattern. Sons will stay and daughters will move in with their husbands' families. Families living in a patrilocal residence generally assume joint ownership of domestic sources. The household is led by a senior member, who also directs the labor of all other members.
Matrilocal residence may be regarded as the opposite of patrilocal residence.
Early theories explaining the determinants of postmarital residence (e.g., Lewis Henry Morgan, Edward Tylor, or George Peter Murdock) connected it with the sexual division of labor. However, to date, cross-cultural tests of this hypothesis using worldwide samples have failed to find any significant relationship between these two variables. However, Korotayev's tests show that the female contribution to subsistence does correlate significantly with matrilocal (as opposed to patrilocal) residence in general; however, this correlation is masked by a general polygyny factor. Although an increase in the female contribution to subsistence tends to lead to matrilocal residence, it also tends simultaneously to lead to general non-sororal polygyny which effectively destroys matrilocality, and pushes a social system toward patrilocality. If this polygyny factor is controlled (e.g., through a multiple regression model), division of labor turns out to be a significant predictor of postmarital residence.
