The Changing Demography of America's Families

We use data from a variety of sources to describe recent dramatic changes in the composition, economic stability, and diversity of American families. The declining prevalence of early marriage, increasing level of marital dissolution, and growing tendency to never marry, especially among some racial and ethnic groups, reflect changes in the relative economic prospects of men and women and support the conclusion that marriage is becoming less valued as a source of economic stability. These developments also imply that relatively more children are born outside of marriage, spend at least part of their childhood in a single‐parent household, and endure multiple changes in family composition. Paralleling these trends have been sharp changes in the economic stability of families, characterized most notably by a growing importance of women's income and increasing economic inequality among American families.
