Enduring and accumulated advantages and disadvantages in work and familylives remain invisible in studies focusing on single outcomes. Further,single outcome studies tend to conflate labor market inequalities related togender, race, and family situation. We combine an intersectional andquantitative life course perspective to analyze parallel work and familylives for Black and White men and women aged 22–44. Results using sequenceanalysis and data from the National Longitudinal Survey of Youth (NLSY79)show that White men enjoy privileged opportunities to combine work and familylife and elicit specific gendered and racialized constraints for Black menand women and White women. Black women experience the strongestinterdependence between work and family life: events in their work livesconstrain and condition their family lives and vice versa. For Black men,stable partnerships and career success mutually support and sustain eachother over the life course. In contrast, for Black women, occupationalsuccess goes along with the absence of stable partnerships. Precarious andunstable employment is associated with early single parenthood for all groupssupporting instability spillovers between life domains that are mostprevalent among Black women, followed by Black men. The findings highlight asizeable group of resourceful Black single mothers who hold stablemiddle-class jobs and have often gone unnoticed in previous research. Weconclude that economic interventions to equalize opportunities in education,employment, and earnings, particularly early in life, are more promising forreducing intersectional inequalities in work-family life courses thanattempting to intervene in family lives.
