Brad Wilcox looks closely at how the institution of marriage has changed over the past several decades, with particular attention to “Middle America,” defined as middle-income Americans with high school education. Prof. Wilcox argues that increases in cohabitation, out-of-wedlock births, and divorce — which were common among the lowest socio-economic sectors of society in the 1960s and ’70s — is becoming increasingly common among “Middle America” today. We discuss some of the reasons for this trend and talk about various solutions. We close with a discussion of evangelicals men and parenting.
