How has cohabiting affected marriage? Cohabiting has skyrocketed, increasing from 430,000 couples in 1960 to 7.5 million today. And it’s not just young people doing it. In fact, women ages 40 to 44 experienced the greatest increase in cohabitation – a 163 percent increase in the last 20 years.
Cohabiting is growing quickly in the 40-plus age group, among divorced and widowed adults who want close relationships but don’t want to blend their families or complex portfolios of assets.
