Introduction

An orthographic projection of geopolitical Oceania

Oceania (UK: /ˌsiˈɑːniə, ˌʃi-, -ˈn-/, US: /ˌʃiˈæniə/ (About this soundlisten), /-ˈɑːn-/) is a geographic region comprising Australasia, Melanesia, Micronesia and Polynesia. Spanning the eastern and western hemispheres, Oceania covers an area of 8,525,989 square kilometres (3,291,903 sq mi) and has a population of 40 million. Situated in the southeast of the Asia-Pacific region, Oceania, when compared to continental regions, is the smallest in land area and the second smallest in population after Antarctica.

The islands at the geographic extremes of Oceania are the Bonin Islands, a politically integral part of Japan; Hawaii, a state of the United States; Clipperton Island, a possession of France; the Juan Fernández Islands, belonging to Chile; and the Campbell Islands, belonging to New Zealand. Oceania has a diverse mix of economies from the highly developed and globally competitive financial markets of Australia and New Zealand, which rank high in quality of life and human development index, to the much less developed economies that belong to countries such as Kiribati and Tuvalu, while also including medium-sized economies of Pacific islands such as Palau, Fiji and Tonga. The largest and most populous country in Oceania is Australia, with Sydney being the largest city of both Oceania and Australia.
