British Indian Ocean Territory

The territory covers a relatively small land area of 60 square kilometers, yet its strategic importance is immense due to the presence of the US military base on Diego Garcia. This small land footprint belies its critical role in global military and logistical operations.

Despite being physically located in the central Indian Ocean, BIOT is officially categorized under the 'Africa' region and 'Eastern Africa' subregion. This classification reflects geopolitical and historical administrative groupings rather than strict geographical proximity to the African continent.

With a population of zero and a defined land area of 60 square kilometers, the population density calculation is mathematically zero. This contrasts sharply with almost every other territory globally, highlighting its status as an uninhabited, strategically controlled zone.

Diego Garcia is listed as the capital of BIOT, yet the territory has no permanent population. This creates the unusual scenario of a capital city designation serving purely administrative or military purposes rather than acting as a center for civilian life or governance.
