The designation mainland Portugal is used to differentiate the continental territory of Portugal from its insular territory. The latter comprises the archipelagos of Madeira and Azores in the Atlantic Ocean. The Azores and Madeira are also commonly referred to as the autonomous regions (Portuguese: as regiões autónomas), insular Portugal (Portuguese: Portugal Insular) or, simply, the islands (Portuguese: as ilhas).
While in modern Portugal the difference between European continental and total territory is minor (in terms of area), it mattered during the existence of the Portuguese Empire, when the distinction was more frequently made, such as in the colonisation of Brazil. Continental Portugal has an area of 89,015 square kilometres (34,369 sq mi) or 96.6% of the Portuguese national territory (92,145 square kilometres (35,577 sq mi)) and 10,142,079 inhabitants (or 95.3% of the total population of 10,639,726).[1]
