The pattern of racial identification among Puerto Ricans is not uniform. It varies depending on where they live. Most identify as white, but more do so in Puerto Rico than in the USA. This paper addresses the impact that living alternatively in the USA and in Puerto Rico has on racial identification among Puerto Ricans. Using Public Use Microdata Sample data from the American Community Survey and the Puerto Rico Community Survey 2006–2008, I find that while there is no single pattern of impact, those more grounded on the island's racial system are more likely to identify as white in the USA, while those less grounded in Puerto Rico are more likely to identify as multiracial or by another racial descriptor. On their return to the island, they revert to the prevalent pattern of racial identification, while still exhibiting effects of their sojourn on their racial identity.
