Puerto Rico, officially the Commonwealth of Puerto Rico (Spanish: "Estado Libre Asociado de Puerto Rico"), is an unincorporated territory of the United States located in the northeastern Caribbean, east of the Dominican Republic and west of the Virgin Islands. Puerto Rico, geographically, is composed of an archipelago that includes the main island of Puerto Rico and a number of smaller islands and keys, the largest of which are Vieques, Culebra, and M...ona. The main island of Puerto Rico is the smallest by land area and second smallest by population among the four Greater Antilles, which also include Cuba, Hispaniola, and Jamaica. Ethnically, the people of Puerto Rico "constitute a Latin American and Caribbean nation that has its own unequivocal national identity".

Puerto Ricans often call the island Borinquen, from Borikén, its indigenous Taíno name. The terms boricua and borincano derive from Borikén and Borinquen respectively, and are commonly used to identify someone of Puerto Rican heritage. The island is also popularly known as "La Isla del Encanto," which translates in English to "The Island of Enchantment."

 

San Juan is the capital and most populous municipality in Puerto Rico. San Juan serves as one of Puerto Rico's most important seaports, and is the island's manufacturing, financial, cultural, and tourism center. The population of the Metropolitan Statistical Area, including San Juan and the municipalities of Bayamón, Guaynabo, Cataño, Canóvanas, Caguas, Toa Alta, Toa Baja, Carolina and Trujillo Alto, is about 2 million inhabitants; thus, about half the population of Puerto Rico now lives and works in this area.[5] San Juan is also a principal city of the San Juan-Caguas-Fajardo Combined Statistical Area. The city has been the host of numerous important events within the sports community, including the 1979 Pan American Games, 1966 Central American and Caribbean Games, 2006 and 2009 World Baseball Classics and the Caribbean Series. The city of San Juan was called Puerto Rico meaning "rich port", and the entire island was called San Juan. The capital and the island's names were later accidentally switched.
