The Virgin Islands, often called the British Virgin Islands (BVI), is a British overseas territory, located in the Caribbean to the east of Puerto Rico.
The five administrative subdivisions mentioned on some web pages may just be planning regions, without much administrative relevance:
The Virgin Islands are located between the Atlantic Ocean and the Caribbean Sea. They extend from west to east about 60 miles, at the top of the arc of Caribbean islands. They are 40 to 50 miles east of Puerto Rico. The arc of Caribbean islands begins off the coast of Florida and extends all the way to South America and includes hundreds of islands and cays.
