A new study found that in 11 countries across the globe, cohabiting couples have more doubts about their relationship lasting and give less importance to their relationship than married couples do.

The 2018 Global Family and Gender Survey (GFGS) examined living situations in various countries. It found that among adults age 18-50 with children under age 18 living at home, married couples had more confidence in the permanence of their relationships than those who were unmarried but living together.
