U.S. Virgin Islands

The United States Virgin Islands are a cluster of islands in the eastern Caribbean, just east of Puerto Rico, made up of three main islands - St. Croix, St. Thomas, and St. John - and dozens of smaller cays. Purchased from Denmark in 1917 for their strategic position near the approaches to the Panama Canal, they form an unincorporated U.S. territory and are the only place under the American flag where traffic drives on the left, a legacy of their Danish past.

St. Thomas and its harbor capital, Charlotte Amalie, are the tourism hub and a major cruise-ship port, while larger St. Croix to the south holds most of the territory's industry and St. John is largely protected as a national park. Tourism dominates an economy set against steep green hills and turquoise water. The islands' roughly 87,000 residents are U.S. citizens without a vote for president.
