There have been decades of research on wage gaps for groups based on their socially salient identities, such as race and gender, but little empirical investigation on the effects of holding multiple identities. Using the Current Population Survey, this study provides new evidence on intersectionality and the wage gap in the US. This article makes two important contributions. First, there is no single “gender” or “race” wage penalty. Second, the evidence suggests that holding multiple identities cannot readily be disaggregated in an additive fashion. Instead, in a comparison of Black and White workers across gender, this study documents that the penalties associated with the combination of two or more socially marginalized identities interact in multiplicative or quantitatively nuanced ways. Further, the findings demonstrate that the presence of an additional intersectional penalty for Black women persists across time.
