Saint Thomas, U.S. Virgin Islands

Geography and environment

Saint Thomas covers about 80.9 km² (31.24 sq mi) of mostly hilly terrain with deep bays and coral-fringed beaches. The landscape is tropical, with dry and wet seasons that support coastal mangroves, reefs and upland vegetation. Popular shorelines include small white-sand beaches and protected coves that serve as bases for boating, snorkeling and diving.

History

Long inhabited by Indigenous Caribbean peoples before European contact, Saint Thomas later became part of the Danish colonial holdings known as the Danish West Indies. Sugar plantation agriculture and the transatlantic slave trade shaped much of its colonial economy and society. Denmark sold the islands to the United States in the early 20th century, after which Saint Thomas developed under U.S. territorial administration.

Population and government

According to the 2000 census, Saint Thomas had 51,181 residents, roughly 47% of the territory's population at that time. Residents are citizens of the United States and local government operates within the framework of the U.S. territorial system. English is the principal language of administration and business.

Economy and transportation

Tourism is the dominant industry, with Charlotte Amalie serving as a major cruise-ship port and duty-free shopping destination. The island also supports small-scale agriculture, service industries and marine activities. Transportation links include an international airport, inter-island ferries and regular boat services to neighboring islands, making Saint Thomas a regional hub.
