Released today by a group of 18 family scholars, Why Marriage Matters powerfully summarizes major new findings from the social sciences on the state of marriage and family life in the U.S. While divorce rates for families with children have fallen, family instability continues to increase for the nation's children overall, mainly because more than 40 percent of American children will now spend time in a cohabiting household.

NEW YORK, Aug. 16, 2011 (GLOBE NEWSWIRE) -- Today, the Center for Marriage and Families released Why Marriage Matters: Thirty Conclusions from the Social Sciences, a scholarly report that includes major new findings on the impact of cohabitation and divorce on children and families. This third edition of Why Marriage Matters is co-sponsored by the Center for Marriage and Families at the Institute for American Values and the National Marriage Project at the University of Virginia. Chaired by Professor W. Bradford Wilcox of the University of Virginia, the report is co-authored by eighteen family scholars from leading institutions including the University of California at Berkeley, Brookings Institution, University of Chicago, Penn State, University of Minnesota, University of Texas at Austin, Urban Institute, and the University of Virginia.

For most of the latter-half of the twentieth century, divorce posed the greatest threat to child well-being and the institution of marriage. Today, that is not the case. New research—made available for the first time in Why Marriage Matters—shows that the rise of cohabiting households with children is the largest unrecognized threat to the quality and stability of children's lives in today's families.

According to W. Bradford Wilcox, lead author of the report, "In a striking turn of events, the divorce rate for married couples with children has returned almost to the levels we saw before the divorce revolution kicked in during the 1970s. Nevertheless, family instability is on the rise for American children as a whole. This is mainly because more couples are having children in cohabiting unions, which are very unstable. This report also indicates that children in cohabiting households are more likely to suffer from a range of emotional and social problems—drug use, depression, and dropping out of high school—compared to children in intact, married families."

Major findings of the report include:

  • Divorces involving children have largely returned to pre-Divorce Revolution levels. Specifically, about 23% of children whose parents married in the early 1960s divorced by the time the children turned 10. More recently, slightly more than 23% of children whose parents married in 1997 divorced by the time the kids turned 10.
  • Family instability for U.S. children overall continues to increase. The data shows that 66% of 16-year-olds were living with both parents in the early 1980s, compared to just 55% of 16-year-olds in the early 2000s. This shift is due to more children being born outside of marriage—especially to cohabiting couples—and the fact that these non-marital unions are overall much less stable.
  • Cohabitation is playing a growing role in children's lives. Children are now more likely to be exposed to a cohabiting union than to a parental divorce. The report indicates that 24% of kids born to married parents will see their parents divorce or separate by age 12, while 42% of kids will experience a parental cohabitation by age 12.
  • Children born to cohabiting unions are much more likely to experience a parental breakup compared to children born to married couples. In the U.S., the report finds that the breakup rate is 170% higher for children born to cohabiting couples up to age 12. Even in Sweden, children born to cohabiting couples are 70% more likely to see parents separate by age 15, compared to children born to married parents.
  • Not only is cohabitation less stable, it is more dangerous for children. Federal data shows that children are at least three times more likely to be physically, sexually, or emotionally abused in cohabiting households, compared to children in intact, biological married parent homes. They are also significantly more likely to experience delinquency, drug use, and school failure.

Based on the new data now available, the authors of Why Marriage Matters offer three conclusions regarding marriage and families in America today:

  1. The intact, biological, married family remains the Gold Standard for family life in the United States. Children are most likely to thrive, economically, socially, and psychologically, in this family form.
  2. Marriage is an important public good, associated with a range of economic, health, educational, and safety benefits that help local, state, and federal governments serve the common good.
  3. The benefits of marriage extend to poor, working class, and minority communities, despite the fact that marriage has weakened in these communities in the last four decades.

THE REPORT surveys more than 250 peer-reviewed journal articles on marriage and family life in the United States and around the world, and also contains original analysis of data from the General Social Survey and the Survey of Income and Program Participation.

THE NATIONAL MARRIAGE PROJECT, founded in 1997 at Rutgers University, is a nonpartisan, nonsectarian, and interdisciplinary initiative now located at the University of Virginia. The Project's mission is to provide research and analysis on the health of marriage in America, to analyze the social and cultural forces shaping contemporary marriage, and to identify strategies to increase marital quality and stability. Directed by W. Bradford Wilcox, a professor of sociology at the university, its publications include the annual "State of Our Unions" report.

THE CENTER FOR MARRIAGE AND FAMILIES is located at the Institute for American Values, a nonprofit, nonpartisan organization dedicated to strengthening families and civil society in the U.S. and the world. Directed by Elizabeth Marquardt, the Center's mission is to increase the proportion of U.S. children growing up with their two married parents. At the Center's website,, bloggers include emerging voices and senior scholars with distinctive expertise and points of view tackling today's key debates on the family.
