To understand the dramatic declines in marriage among blacks, we must consider broad changes in the labor force as well as changing ideas about gender and family relationships. These changes made employment and earnings, especially those of women, more important for forming stable families. Changing ideas about family affected both whites and blacks, but they affected black families earlier and more strongly because blacks were and continue to be more economically vulnerable. Since 1980, as economic restructuring has eroded opportunities for less-educated whites, they too are seeing dramatic changes in family life.
