British Indian Ocean Territory

The British Indian Ocean Territory stands out globally with a reported permanent population of zero. This highly unusual demographic profile is due to its primary function as a military base, where inhabitants are typically transient personnel.

Diego Garcia is listed as the capital of the British Indian Ocean Territory, yet the territory itself has no permanent population. This highlights its administrative and strategic importance as a military installation rather than a traditional civilian settlement.

With a modest land area of 60 square kilometers, the British Indian Ocean Territory holds disproportionate global strategic importance. Its small size belies its role as a key military outpost, particularly the island of Diego Garcia.

Despite being categorized within the 'Africa' region and 'Eastern Africa' subregion, the British Indian Ocean Territory has no indigenous or permanent African population. Its administrative classification contrasts sharply with its demographic reality.
