More than 40 percent of children are born out of wedlock, while more than half of births (53 percent) among all women under 30 now occur outside of marriage. Between 1970 and 2012, the annual number of marriages per 1,000 unmarried adults decreased by more than 50 percent. The divorce rate today is about twice that of 1960, though it’s declined since hitting its highest point in our history in the early 1980s. For the average couple marrying for the first time in recent years, the lifetime probability of divorce or separation now falls between 40 and 50 percent. Today more than a quarter of all children live in single-parent families, compared to only 9 percent in 1960. And the number of unmarried couples has increased seventeen-fold in the last 50 years.

All of this has profoundly negative implications–for the emotional and mental well-being of children; for America’s social fabric and “civil society”; for social mobility and the gap in income inequality; and for dependency on government and costs to the state (family breakdown costs the taxpayers billions every year). The collapse of marriage in America, then, has enormous human and social ramifications. And whatever one thinks about same-sex marriage, this collapse has occurred long before any state approved marriage between gays.

The report offers a range of recommendations to reverse this trend, including eliminating marriage penalties and disincentives for the poor and for unwed mothers, tripling the child tax credit, providing marriage education and evaluating marriage programs, engaging Hollywood to help shape positive attitudes toward marriage and parenting, launching social media campaigns, and presidential leadership on this issue.
