Christianity Today spoke with a sociology professor, Bradford Wilcox, and his colleagues about a study titled, "The Cohabitation-Go-Round: Cohabitation and Family Instability Across the Globe." The study found that children were more often than not negatively affected by cohabiting parents, regardless of class or education level, specifically in the stability of the family. The study also found that a widespread acceptance of cohabitation in one culture did not make it as stable as marriage.
