Puerto Rican citizenship
In 1952, upon U.S. Congress approving the Constitution of the Commonwealth of Puerto Rico, also reaffirmed that Puerto Rican citizenship continued in full force. This was further reaffirmed in 2006 while the U.S. Senate probed into the President's Task Force on Puerto Rico's status. In 1953, U.S Ambassador Henry Cabot Lodge Jr., in a memorandum sent to the United Nations, recognized that "the people of Puerto Rico continue to be citizens of the United States as well as of Puerto Rico."
Puerto Ricans in the United States
According to the 2010 US census, of the stateside Puerto Rican population, about 53.1% self-identified as white, about 8.7% self-identified as black, about 0.9% as American Indian, about 0.5% as Asian, and 36.7% as mixed or other. Though over half self-identified as white, the Puerto Rican population is largely made up of multi-racials, most Puerto Ricans are mixed to varying degrees, usually of white European/North African, black West African, and indigenous Taino ancestry. The average genomewide individual ancestry proportions have been estimated as 56% European, 28% West African, and 16% Native American. However, there are significant numbers of (pure or nearly pure) blacks and whites within the Puerto Rican population as well. Historically, under Spanish and American rule, Puerto Rico underwent a whitening process, in particular, the island had laws like the "Regla del Sacar", in which people of mixed-race origin were identified as "white", the opposite of the one-drop rule in the United States.
