This study compares trends in work-family context by education level from 1976 to 2011 among U.S. women. The major aim is to assess whether differences in work-family context by education level widened, narrowed, or persisted. We used data from the 1976-2011 March Current Population Surveys on women aged 25-64 (n=1,597,914). We compare trends in four work-family forms by education level within three race/ethnic groups. The work-family forms reflect combinations of marital and employment status among women with children at home. Trends in the four work-family forms exhibited substantial heterogeneity by education and race/ethnicity. Educational differences in the work-family forms widened mainly among white women. Compared with more-educated peers, white women without a high school credential became increasingly less likely to be married, to be employed, to have children at home, and to combine these roles. In contrast, educational differences in the work-family forms generally narrowed among black women and were directionally mixed among Hispanic women. Only one form-unmarried and employed with children at home-became more strongly linked to a woman's education level within all three race/ethnic groups. This form carries an elevated risk of work-family conflict and its prevalence increased moderately during the 35-year period. Taken together, the trends underscore recent calls to elevate work-family policy on the national agenda.
