Though considerable research demonstrates that non-Hispanic blacks and non-Hispanic whites in the USA vary in how much their health improves from educational attainment, empirical work that explains why these populations arrive at unequal returns to education is sparse. In this study, to flesh out our understanding of how heterogeneous educational gradients arise among racial populations in the USA, I examine how income—a crucial mediator of the education–health association—contributes to racially disparate health returns to college. In particular, I compare how the association among college completion and health status would manifest across blacks and white subpopulations if income were factored out of the underlying education–health generative process. I use data from the National Longitudinal Study of Adolescent to Adult Health (n = 7222) and sequential g-estimation for this investigation. Results demonstrate that income plays a larger role in mediating the association among college completion and health status for blacks and, as such, that sizable racial differences in the health benefits of college persist after controlling for income.

过程中的不平等：美国黑人和白人之间的收入和异构教育健康梯度

虽然相当多的研究表明，非西班牙裔黑人和非西班牙裔白人在美国在改变多少自己的健康，从受教育程度，解释实证研究改进，为什么这些人群处于不平等的教育回报率到达稀疏。在本研究中，为充实我们对美国种族人口中不同的教育梯度的产生的理解，我研究了收入（教育健康协会的重要调解人）如何为不同种族的大学健康回报做出贡献。特别是，我比较了如果将收入从基础教育中剔除，那么在黑人和白人子群中，大学结业与健康状况之间的关系将如何体现出来–健康生成过程。我使用了《从青少年到成人健康的国家纵向研究》（n  = 7222）中的数据并进行了连续g估计。结果表明，收入在调解黑人的大学学历与健康状况之间的关系中起着更大的作用，因此，控制收入后，大学在健康福利方面的种族差异仍然存在。
