Many romantic couples who live together without being married do so out of wariness about the high divorce rate. Cohabiting, for these couples, can be a “trial” relationship period in which they decide their compatibility before marrying.

Until recently, previous research conclusions and popular conception held that cohabiting couples who eventually married experienced higher divorce rates than those who did not live together before marriage.

A new study by University of North Carolina-Greensboro sociologist Arielle Kuperberg proves this assumption false. Using data from the National Survey of Family Growth, Kuperberg analyzed the divorce rate among 7,000 people who had been married at least once. Kuperberg also incorporated other variables, such as the date the couple moved in together. Contrary to 1970s research, Kuperberg found no link between cohabitation and divorce.

Cornell University sociologist Sharon Sassler, in pursuit of research for her book on cohabitation, interviewed more than 150 cohabiters. She found that persons with college degrees date longer before moving in together. Those with degrees date for an average of 14 months compared to 6 months or less for non-degree holders.

As cohabitation becomes more common among couples, sociological research is investigating and dispelling myths about the intricacies of romantic relationships, turning common (and fallacious) knowledge on its head.
