Statistical information British Indian Ocean Territory 1993
British Indian Ocean Territory in the World
top of pageBackground: Established as a territory of the UK in 1965 a number of the British Indian Ocean Territory (BIOT) islands were transferred to the Seychelles when it attained independence in 1976. Subsequently BIOT has consisted only of the six main island groups comprising the Chagos Archipelago. The largest and most southerly of the islands Diego Garcia contains a joint UK-US naval support facility. All of the remaining islands are uninhabited. Former agricultural workers earlier resident in the islands were relocated primarily to Mauritius but also to the Seychelles between 1967 and 1973.
