The Rising Share of Nonmarital Births: Fertility Choices or Marriage Behavior?

Abstract

Much of the sharp rise in the share of nonmarital births in the United States has been attributed to changes in the fertility choices of unmarried and married women - in response, it is often argued, to various public policies. In contrast, we develop and test a model that attributes the rise to changes in marriage behavior, with no changes in fertility. A variety of empirical tests strongly supports this conclusion and invites focused attention to issues related to marriage behavior, as well as the interactions between marriage and fertility.
