This book explores how the breakdown of marriage in the United States is creating a nation of separate and unequal families. It begins by tracing the origins of the unmarriage revolution and the rupture between marriage and child-rearing. The rise of older unmarried mothers is discussed, as well as the number of African American children born to single mothers, the negative impact of single parenthood on children, and the development of the Marriage Gap. Chapter 2 considers the benefits of marriage throughout history, the cultural revolution that led to widespread divorce and illegitimacy, and the argument against gay marriage. Following chapters explain the impact of the Moynihan Report and unmarriage in the African American community, the loss of child-centeredness in low-income single mother families, the consequences of the unmarriage revolution for urban African American men, and the rise of teenage minority mothers. Chapter 7 discusses the end of the Feminist movement, the desire of most young women to marry and have children, and the trend towards staying home with the children. The final chapter examines positive trends in America that indicate a drop in teen pregnancy rates and a stabilization of the divorce rate.
