In decades past, most Americans married, and most American children were raised within two-parent families. But now marriage rates have fallen; 40% of American children are born outside of wedlock, and approximately a quarter live in single-parent homes. The United States has by far the world’s highest rate of children living in single-parent households — more than three times the global average. 

Melissa Kearney, who is an economics professor at the University of Maryland and Director of the Aspen Economic Strategy Group, investigates the reasons for this sea change in American family formation and its consequences in her important new book The Two-Parent Privilege: How Americans Stopped Getting Married and Started Falling Behind. Kearney finds overwhelming evidence that children from single-parent homes have more behavioral problems, are more likely to get in trouble in school or with the law, achieve lower levels of education, and tend to earn lower incomes in adulthood. And she also finds that since college-educated parents have largely continued to have and raise children in two-parent homes, the move away from marriage and two-parent families is worsening inequality and widening the class divide between college-educated and non-college-educated Americans.  

In this podcast discussion, Kearney analyzes the reasons for the decline of marriage and the rise of single parenthood, along with the significant variance in two-parent households among different ethnic and racial groups. She also talks about why academics have been reluctant to publicly discuss the impact of single parenthood on kids’ outcomes, the reasons why both the political left and right have criticized her analysis, and some potential policy solutions to the social dynamics that are “disadvantaging children and will perpetuate across generations if we don’t immediately do something about it.”
