Puerto Rican citizenship
A 1918 official report from the American colonial governor of Puerto Rico to the U.S. Secretary of War, this one after the Jones Act of 1917, had become law, states that the "passports...[are used to] prove a person's nationality," thus making clear that Puerto Rican citizenship and Puerto Rican nationality were one and the same. The United States government also recognizes this status in its own records. For example, the CIA World Fact Book, states that the nationality of Puerto Ricans is not "American" but, in fact, ""Puerto Rican"." The Spanish Government also recognizes Puerto Ricans as a people with Puerto Rican, "and not American," citizenship. It also provides Puerto Rican citizens privileges not provided to citizens of several other nations, such as Haití, Jamaica, Trinidad y Tobago y Guyana. Since 2007, the Government of Puerto Rico has been issuing "Certificates of Puerto Rican Citizenship" to anyone born in Puerto Rico or born outside of Puerto Rico with at least one parent who was born in Puerto Rico.
Demographics of New York City
New York City has the largest Puerto Rican population outside of Puerto Rico. Attributable to the changing citizenship status of the island's residents, Puerto Ricans can technically be said to have come to the City first as immigrants and subsequently as migrants. The first group of Puerto Ricans moved to New York in the mid-19th century, when Puerto Rico was a Spanish colony and its people Spanish subjects. The following wave of Puerto Ricans to move to New York did so after the Spanish–American War of 1898 made Puerto Rico a U.S. possession and after the Jones–Shafroth Act of 1917 gave Puerto Ricans U.S. citizenship, which allows travel without the need of a passport between the island and the United States mainland. The largest wave of migration came in the 1950s, in what became known as "The Great Migration"; as a result, more than a million Puerto Ricans once called New York City home. Presently the Puerto Rican population is around 800,000.
