The Turks and Caicos Islands (abbreviated TCI; /tɜːrks/ and /ˈkeɪkəs, -koʊs, -kɒs/) are a British Overseas Territory consisting of the larger Caicos Islands and smaller Turks Islands, two groups of tropical islands in the Lucayan Archipelago of the Atlantic Ocean and northern West Indies. They are known primarily for tourism and as an offshore financial centre. The resident population in July 2021 was put at 57,196, making it the third-largest of the British overseas territories by population. The islands are southeast of Mayaguana in the Bahamas island chain and north of the island of Hispaniola (Haiti and the Dominican Republic). Grand Turk (Cockburn Town), the capital since 1766, is situated on Grand Turk Island about 1,042 kilometres (647 mi) east-southeast of Miami, United States. They have a total land area of 430 square kilometres (170 sq mi). The islands were inhabited for centuries by indigenous peoples. The first recorded European sighting of them was in 1512. In subsequent centuries, they were claimed by several European powers, with the British Empire eventually gaining control. For many years they were governed indirectly through Bermuda, the Bahamas and Jamaica. When the Bahamas gained independence in 1973, the islands received their own governor, and have remained an autonomous territory since.
