Cohabitation is an arrangement where people who are not legally married live together as a couple. They are often involved in a romantic or sexually intimate relationship on a long-term or permanent basis. Such arrangements have become increasingly common in Western countries since the late 20th century, led by changing social views, especially regarding marriage. The term dates from the mid 16th century, being used with this meaning as early as 1530.^[1]
