This paper quantifies the extent to which individuals experience changes in reported racial identity in the historical U.S. context. Using the full population of historical Censuses for 1880-1940, we document that over 19% of black males “passed” for white at some point during their lifetime, around 10% of whom later “reverse-passed” to being black; passing was accompanied by geographic relocation to communities with a higher percentage of whites and occurred the most in Northern states. The evidence suggests that passing was positively associated with better political-economic and social opportunities for whites relative to blacks. As such, endogenous race is likely to be a quantitatively important phenomenon.
