 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.If this polygyny factor is controlled (e. g., through a multiple regression model), division of labour turns out to be a significant predictor of postmarital residence.Thus, Murdock's hypotheses regarding the relationships between the sexual division of labour and postmarital residence were basically correct, though, as has been shown by Korotayev, the actual relationships between those two groups of variables are more complicated than he expected.
