Puerto Rico (Spanish for 'rich port'; abbreviated PR; Taino: Boriken, Borinquen), officially the Commonwealth of Puerto Rico (Spanish: Estado Libre Asociado de Puerto Rico, lit. 'Free Associated State of Puerto Rico'), is a Caribbean island and unincorporated territory of the United States with official Commonwealth status. It is located in the northeast Caribbean Sea, approximately 1,000 miles (1,600 km) southeast of Miami, Florida, between the Dominican Republic and the U.S. Virgin Islands, and includes the eponymous main island and several smaller islands, such as Mona, Culebra, and Vieques. It has roughly 3.2 million residents, and its capital and most populous city is San Juan. Spanish and English are the official languages of the executive branch of government, though Spanish predominates.Puerto Rico was settled by a succession of indigenous peoples beginning 2,000 to 4,000 years ago; these included the Ortoiroid, Saladoid, and Taíno. It was then colonized by Spain following the arrival of Christopher Columbus in 1493. Puerto Rico was contested by other European powers, but remained a Spanish possession for the next four centuries. An influx of African slaves and settlers primarily from the Canary Islands and Andalusia vastly changed the cultural and demographic landscape of the island. Within the Spanish Empire, Puerto Rico played a secondary but strategic role compared to wealthier colonies like Peru and New Spain. By the late 19th century, a distinct Puerto Rican identity began to emerge, centered around a fusion of indigenous, African, and European elements. In 1898, following the Spanish–American War, Puerto Rico was acquired by the United States.Puerto Ricans have been U.S. citizens since 1917, and can move freely between the island and the mainland. However, as residents of an unincorporated territory, American citizens of Puerto Rico are disenfranchised at the national level, do not vote for the president or vice president, and generally do not pay federal income tax. In common with four other territories, Puerto Rico sends a nonvoting representative to the U.S. Congress, called a Resident Commissioner, and participates in presidential primaries; as it is not a state, Puerto Rico does not have a vote in Congress, which governs it under the Puerto Rico Federal Relations Act of 1950. Congress approved a local constitution in 1952, allowing U.S. citizens residing on the island to elect a governor. Puerto Rico's current and future political status has consistently been a matter of significant debate.Beginning in the mid-20th century, the U.S. government, together with the Puerto Rico Industrial Development Company, launched a series of economic projects to develop Puerto Rico into an industrial high-income economy. It is classified by the International Monetary Fund as a developed jurisdiction with an advanced, high-income economy; it ranks 40th on the Human Development Index. The major sectors of Puerto Rico's economy are manufacturing (primarily pharmaceuticals, petrochemicals, and electronics) followed by services (namely tourism and hospitality).Immigration and emigration
As of 2019, Puerto Rico was home to 100,000 permanent legal residents. The vast majority of recent immigrants, both legal and illegal, come from the Dominican Republic and Haiti. Other major sources of recent immigrants include Cuba, Mexico, Colombia, Panama, Jamaica, Venezuela, Spain, and Nigeria. Additionally, there are many non-Puerto Rican U.S. citizens settling in Puerto Rico from the mainland United States and the U.S. Virgin Islands, as well as Nuyoricans  and other stateside Puerto Ricans coming back. Most recent immigrants settle in and around San Juan.
Emigration is a major part of contemporary Puerto Rican history. Starting soon after World War II, poverty, cheap airfares, and promotion by the island government caused waves of Puerto Ricans to move to the United States mainland, particularly to the northeastern states and nearby Florida. This trend continued even as Puerto Rico's economy improved and its birth rate declined. Puerto Ricans continue to follow a pattern of "circular migration", with some migrants returning to the island. In recent years, the population has declined markedly, falling nearly 1% in 2012 and an additional 1% (36,000 people) in 2013 due to a falling birthrate and emigration. The impact of hurricanes Maria and Irma in 2017, combined with the unincorporated territory's worsening economy, led to its greatest population decline since the U.S. acquired the archipelago.
According to the 2010 Census, the number of Puerto Ricans living in the United States outside of Puerto Rico far exceeds those living in Puerto Rico. Emigration exceeds immigration. As those who leave tend to be better educated than those who remain, this accentuates the drain on Puerto Rico's economy.
Based on 1 July 2019 estimate by the U.S. Census Bureau, the population of the Commonwealth had declined by 532,095 people since the 2010 Census data had been tabulated.Population distribution
The most populous municipality is the capital, San Juan, with 342,259 people based on the 2020 Census. Other major cities include Bayamón, Carolina, Ponce, and Caguas. Of the ten most populous cities on the island, eight are located within what is considered San Juan's metropolitan area, while the other two are located in the south (Ponce) and west (Mayagüez) of the island.
