Living apart together

Abstract Traditionally, marriage has been the social institution for couples that have been together for a long period. Some decades ago a new social institution appeared in the Western world: non-marital cohabitation, although this was slower to be accepted in some countries than in others. Living Apart Together (LAT) relationships, are a new phenomenon which seems to have the potential of becoming the third stage in the process of social change. In contrast to couples in commuting marriages which have one household in common, couples living in LAT relationships have one household each. We discuss some data on the frequency of LAT relationships in Sweden and Norway as well as some varieties of the phenomenon. Our analysis suggests that the existence of cohabitation as a social institution, alongside marriage, is a necessary precondition for LATs to be recognised as a social institution. LAT relationships could not exist unless a preceding social institution of cohabitation also exists.
