Naturalization and immigrants’ health

Abstract

The “healthy immigrant effect” refers to the well-documented fact that immigrants are healthier than natives upon arrival, but their health level converges to that of natives over time. Unfortunately, we know little about whether environmental, institutional, or selective return migration mechanisms are behind the convergence. In this paper, I test whether immigrants’ naturalization influences health convergence speed. Using restricted-access Spanish health data from the National and European Health Surveys, I estimate the impact of naturalization on health by exploiting that naturalization is possible after 2 years of residence for immigrants from specific countries and after 10 years for all other immigrants. I find that naturalization worsens immigrants’ health and thus accelerates the speed of convergence to natives’ health. Increases in employment are potential mechanisms behind this effect.
