Couples study debunks 'trial marriage' notion of cohabiting - USATODAY.com
Cohabitation has increased so rapidly that the data about it haven't kept pace with the growing numbers, researchers say. The latest U.S. Census for 2008 reported 13.6 million unmarried, heterosexual couples living together. Researchers say 50% to 60% of couples who marry today lived together first; some note that 70% of young adults will cohabit. Most couples who live together either marry or break up within two years.
