During the study, Daniel T. Lichter of Cornell University and Zhenchao of Ohio State University tracked the experiences of serial cohabiters, or women who have cohabited with more than one partner.
They found that serial cohabiters were less likely to marry; moreover, divorce rates are twice as high for women who cohabited only with their eventual husbands.
"Understanding the myriad motivations of cohabiters may be more important than ever, especially if cyclical serial cohabiting couples with children have increased among recent cohorts as a percentage of all cohabitations," said Lichter.
The study also revealed that only a 15 to 20 percent of cohabiting women were involved in multiple cohabitations.
The study appears in Journal of Marriage and Family (JMF).
