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
In 1950, about a quarter of a million Puerto Rican natives lived "stateside", or in one of the U.S. states. In March 2012 that figure had risen to about 1.5 million. That is, slightly less than a third of the 5 million Puerto Ricans living stateside were born on the island. Puerto Ricans are also the second-largest Hispanic group in the USA after those of Mexican descent.
