Best predictor of divorce? Age when couples cohabit, study says
"Up until now, we've had this mysterious finding that co-habitation causes divorce," she says. "Nobody's been able to explain it. And now we haveit was that people were measuring it the wrong way."
Couples who begin living together without being married tend to be younger than those who move in after the wedding ceremony that's why cohabitation seemed to predict divorce, Professor Kuperburg explains. But once researchers control for that age variable, it turns out that premarital cohabitation by itself has little impact on a relationship's longevity. Those who began living together, unmarried or married, before the age of 23 were the most likely to later split.
"Part of it is maturity, part of it is picking the right partner, part of it is that you're really not set up in the world yet," she says. "And age has to do with economics."
Indeed, other research released by the nonpartisan academic group Monday suggests that the longer couples wait to start living together, the better their chances for long-term relationship success.
