Puerto Rican citizenship
In 1994, Puerto Rican activist Juan Mari Brás flew to Venezuela and renounced his US citizenship before a consular agent in the US Embassy in Caracas. Mari Brás, through his renunciation of U.S. citizenship, sought to redefine Section VII as a source of law that recognized a Puerto Rican nationality separate from that of the United States. In December 1995, his denaturalization was confirmed by the US State Department. Among the arguments that ensued over his action was whether he would now be able to vote in elections in Puerto Rico. On November 18, 1997, the Supreme Court of Puerto Rico through its ruling in "Miriam J. Ramirez de Ferrer v. Juan Mari Brás" reaffirmed the Puerto Rican citizenship by ruling that U.S. citizenship was not a requirement to vote in Puerto Rico. According to the court's majority opinion, the Puerto Rican citizenship is recognized several times in the Puerto Rican constitution including section 5 of article III, section 3 of article IV, and section 9 of article V. In a 2006 memorandum, the Secretary of Justice of Puerto Rico concluded, based on the Mari Brás case, that the Puerto Rican citizenship is "separate and different" from the United States citizenship.
Afro-Latin Americans
According to the 2010 U.S. Census taken in Puerto Rico, 75.8% of Puerto Ricans identified as being white, 12.4% of the population as being black or African American and 11.1% as mixed or of another ethnicity. An island-wide mitochondrial DNA (mtDNA) study conducted by the University of Puerto Rico at Mayagüez revealed that 61% of Puerto Ricans have maternal Native American ancestry, 26.4% have maternal West or Central African ancestry, and 12.6% have maternal European ancestry. On the other hand, the Y chromosome evidence showed Puerto Ricans' patrilineage to be approximately 75% European, 20% African, and less than 5% indigenous.
