The likelihood of ever marrying by midlife (which we define as age 40–44) conveys important information about the nature of group differences in marriage, yet these figures reflect age-specific marriage rates that prevailed at earlier points in time. If we understand the historical timing of the racial divergence in marriage rates with greater precision, we may shed light on what caused the change and variability in family patterns. Sociologists Robert Mare and Christopher Winship report that during the 1960s, marriage rates began to decline much more rapidly for black women than for white women across all age groups.13 Thus looking at age-specific marriage rates suggests that the racial divergence in marriage patterns gained momentum about 10 years earlier than figure 1 suggests, after about 1960.
