Puerto Rican citizenship
On March 2, 1917, the Jones–Shafroth Act was signed, collectively making Puerto Ricans United States citizens without rescinding their Puerto Rican citizenship. In 1922, the U.S. Supreme court in the case of "Balzac v. Porto Rico" ruled that the full protection and rights of the U.S constitution do not apply to residents of Puerto Rico until they come to reside in the United States proper. Luis Muñoz Rivera, who participated in the creation of the Jones-Shafroth Act, gave a speech in the U.S. House floor that argued in favor of Puerto Rican citizenship. He declared that "if the earth were to swallow the island, Puerto Ricans would prefer American citizenship to any citizenship in the world. But as long as the island existed, the residents preferred Puerto Rican citizenship." The Jones Act allowed locals to renounce the United States citizenship and remain exclusively Puerto Rican citizens, at the cost of being stripped of the right to vote. Despite these arbitrary limitations, 287 residents completed the process to forfeit the statutory recognition.
Afro-Puerto Ricans
As of the 2010 Census, 75.8% of Puerto Ricans identify as white, 12.4% identify as black, 0.5% as Amerindian, 0.2% as Asian, and 11.1% as "mixed or other." Although estimates vary, most sources estimate that about 60% of Puerto Ricans have significant African ancestry. The vast majority of blacks in Puerto Rico are Afro-Puerto Rican, meaning they have been in Puerto Rico for generations, usually since the slave trade, forming an important part of Puerto Rican culture and society. Recent black immigrants have come to Puerto Rico, mainly from the Dominican Republic, Haiti, and other Latin American and Caribbean countries, and to a lesser extant directly from Africa as well. Many black migrants from the United States and the Virgin Islands have moved and settled in Puerto Rico. Also, many Afro-Puerto Ricans have migrated out of Puerto Rico, namely to the United States. There and in the US Virgin Islands, they make up the bulk of the U.S. Afro-Latino population.
