Oceania Map
Oceania is a region of the world that is not a continent stricto sensu. However, since this region is often assimilated to a continent by geographers, this part of the world can be considered as the smallest of the continents emerging from the Earth. Located in the Pacific Ocean, it covers an area of 8,525,989 square kilometers and has more than 38 million inhabitants in sixteen independent states and fifteen territories. It encompasses all the lands between Asia and America, as well as part of the Malay archipelago. It is divided into four regions: Australasia, Micronesia, Melanesia and Polynesia. Map 15 March 2014.
The term was coined by the French geographer Conrad Malte-Brun in 1812 as "Océanie", from "Océan" in French which, in turn, derives from the ancient Greek word for Ocean. The meaning of its name is based on the fact that its territory is composed of thousands of small islands scattered in the largest ocean on the planet.
