Living arrangements in contemporary Britain: having a partner who usually lives elsewhere and living apart together (LAT).

This article explores the subject of 'living apart together' (LAT). LAT is a relationship in which the two partners regard themselves as a couple but they are not co-residentially cohabiting. The phenomenon of 'living apart together' is difficult to measure but has become increasingly recognised in international sociological and demographic literature. However, in Great Britain there has so far been little research of this subject and no attempt, until now, to estimate its extent.
