Puerto Rican citizenship
Puerto Rican citizenship was first legislated by the United States Congress in Article 7 of the Foraker Act of 1900 and later recognized in the Constitution of Puerto Rico. Puerto Rican citizenship existed before the U.S. takeover of the islands of Puerto Rico and continued afterwards. Its affirmative standing was also recognized before and after the creation of the Commonwealth of Puerto Rico in 1952. Puerto Rican citizenship was recognized by the United States Congress in the early twentieth century and continues unchanged after the creation of the Commonwealth of Puerto Rico. The United States government also continues to recognize a Puerto Rican nationality. Puerto Rican citizenship was once also recognized by the Spanish Government, which recognized Puerto Ricans as a people with Puerto Rican, and not American citizenship. It also at one time granted Spanish citizenship to Puerto Ricans on the basis of their Puerto Rican (and not American) citizenship.
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.
