History of women in Puerto Rico
Puerto Rico has participated in the Olympics, since the 1948 Summer Olympics, which were celebrated in London, as an independent nation. However, since Puerto Ricans have American citizenship, Puerto Rican athletes have the option of representing Puerto Rico or moving to the United States where after living there for 3 years or more they can represent that country in the games. Some Puerto Ricans, such as Gigi Fernández in tennis, have won gold medals for the U.S. Also, women who are of Puerto Rican heritage are considered by the Government of Puerto Rico to be "Puerto Rican Citizens". Since 2007, the Government of Puerto Rico has been issuing "Certificates of Puerto Rican Citizenship" to anyone born in Puerto Rico or to anyone born outside of Puerto Rico with at least one parent who was born in 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.
