Two people are described as cohabiting if they are living together as a couple but are not married to each other or in a registered same-sex civil partnership together. This includes people living with a partner of the same sex. A cohabiting person might be married or in a civil partnership (with someone not resident in the household) but will not be shown as married, in a civil partnership or separated in results relating to living arrangements because cohabiting in this classification takes priority over legal marital or partnership status.
