Anguilla is a small British dependency located at the northern end of the Leeward Islands in the Caribbean Sea. It is a low-lying, semiarid coral island with an area of 91 sq km (35 sq mi) and a maximum elevation of 61 m (200 ft). Its dry climate and thin soil hamper commercial agricultural development. Anguilla has a number of scenic beaches, and tourism and British aid are important to the economy. Most residents are involved in fishing and subsistence farming, raising such crops as pigeon peas, sweet potatoes, Indian corn, and beans. Anguilla has a population of 6,875 (1988 est.), which is predominantly black.
