In light of those findings, some commentators have argued that reducing the stigma attached to living together outside marriage has been a mistake, leading many young couples to make decisions that put their future marriage at risk.
In the last two years, newer research has suggested that the risk associated with premarital cohabitation may be receding.
Sociologists Wendy Manning and Jessica Cohen found that for marriages formed since the mid-1990s, living together before marriage did not raise the risk of divorce.
This is because they have been comparing couples by their age at marriage rather than by their age when they moved in together.
Women are especially likely to enlist a friend in helping them craft the perfect profile—30% of female online daters have done this, compared with 16% of men.
5% of Americans who are in a marriage or committed relationship say they met their significant other online.
These trends are troubling to some because nearly a dozen studies from the 1970s into the early 2000s showed that men and women who lived together before marriage were far more likely to divorce than couples who moved directly from dating to marriage.
In fact, on average, researchers found that couples who cohabited before marriage had a 33 percent higher chance of divorcing than couples who moved in together after the wedding ceremony.
