The relative education model holds that educational attainment reflects existing socioeconomic advantages that are associated with participation rather than spurring political participation on its own. Yet, emerging research on compensation effects suggests that greater educational attainment leads to increased political engagement among more marginal populations in which political socialization is less likely to occur outside of schools. We argue that the relative education model will better describe the relationship between education and voting patterns among more advantaged groups. We test our expectations by estimating the relative education model within racial and ethnic groups in the U.S. using data from the Current Population Survey’s (CPS) Voting and Registration Supplement from 1978 to 2020. We find that for relatively highly educated White and Asian American voters, each additional year of education yields diminishing returns to turnout. For Black and Latino voters, additional years of education are positively associated with turnout regardless of relative education. The results suggest that opportunities remain to reduce racial turnout gaps and boost political participation by addressing racial gaps in educational attainment.
