Physical pain is a pressing issue for scientists and policymakers. Yet evidence on the psychosocial factors of pain is limited. Using data from 146 countries ( N = 1.3 million individuals), this article documents the role of income comparisons on physical pain. Specifically, this study shows that income rank (i.e., the ordinal position of a person’s income within a comparison group) is linked to physical pain above and beyond absolute income. This effect is identical in rich and poor nations. The negative emotions that result from a disadvantaged relative standing in the income hierarchy may explain these findings. This article documents a new kind of evidence on the power of income comparisons and highlights the role that psychosocial factors may play in physical pain.
