Much of the debate over welfare reauthorization centers on whether marriage promotion should play a key role. Few studies, however, have tracked the marriage and divorce histories of unwed mothers, including minority women, who are often the main targets of welfare reform. Data from the 1995 National Survey of Family Growth were used to estimate the hazards of the transition to marriage for women who delayed childbearing until marriage and for teenagers and older women who had a nonmarital first birth, and of the transition to divorce among the ever-married. Life-table estimates calculated with these estimated transition hazards show the cumulative proportions married and divorced, by race and ethnicity, for women who had a nonmarital first birth and for those who did not.
