Oceania - For the fictional superstate in George Orwell's novel Nineteen Eighty-Four, see 'Oceania (fiction)'.
Oceania is a name used for varying groups of islands of the Pacific Ocean. In its narrow usage it refers to Polynesia (including New Zealand), Melanesia (including New Guinea) and Micronesia. In a wider usage it includes Australia. It may also include the Malay archipelago. Uncommon usage includes islands such as Japan and the Aleutian Islands. Overview Although the islands of Oceania do not form part of a true continent, Oceania is sometimes associated with the continent of Australia for the purposes of dividing the whole world into continental groupings. As such, it is the smallest "continent" in area and the second smallest, after Antarctica, in population. This article primarily refers to the grouping of Polynesia, Melanesia, Micronesia and Australia. These traditional divisions are no more in use amongst researchers, who prefer to divide Oceania into Near Oceania and Remote Oceania. In ecology, Oceania is one of eight terrestrial ecozones, which constitute the major ecological regions of the planet. The Oceania ecozone includes all of Micronesia, Fiji, and all of Polynesia except New Zealand. New Zealand, along with New Guinea and nearby islands, Australia, the Solomon Islands, Vanuatu, and New Caledonia, constitute the separate Australasia ecozone. If the narrower definition is accepted, every country but one in Oceania is borderless. The exception is Papua New Guinea which borders Indonesia. Wider definitions might also allow the borders of Indonesia with Malaysia and Timor Leste, and Malaysia's border with Brunei Darussalam to be considered within Oceania. Regions and Countries The traditional subdivision of Oceania into Micronesia, Melanesia and Polynesia (by the French Dumont d'Urville in 1831) is no more recognised as correct by most geographers and scientists, but it is still the most popular one): Micronesia Melanesia Polynesia Australia 1 Often considered also SouthEast Asian, becouse of past Indonesia occupation.
2 Some Indonesian islands lie in Melanesia - most notably the indonesian part of New Guinea - but as a whole Indonesia is regarded as an asian country.

Unlike the figures in the country articles, the figures in this table are based on areas including inland water bodies (lakes, reservoirs, rivers) and may therefore be lower here. | country | pop. dens. | width="80" | area | width="80" | population | | | (/km²) | (km²) | (2002 est.) | | align="left" | Nauru | 587 | 21 | 12,329 | | align="left" | Tuvalu | 429 | 26 | 11,146 | | align="left" | Marshall Islands | 407 | 181 | 73,630 | | align="left" | American Samoa (US) | 345 | 199 | 68,688 | | align="left" | Guam (US) | 293 | 549 | 160,796 | | align="left" | Micronesia | 194 | 702 | 135,869 | | align="left" | Northern Mariana Islands (US) | 162 | 477 | 77,311 | | align="left" | Tokelau (N.Z.) | 143 | 10 | 1,431 | | align="left" | Tonga | 142 | 748 | 106,137 | | align="left" | Kiribati | 119 | 811 | 96,335 | | align="left" | Cook Islands (N.Z.) | 87 | 240 | 20,811 | | align="left" | East Timor | 68 | 15,007 | 1,019,252 | | align="left" | French Polynesia (Fr.) | 62 | 4,167 | 257,847 | | align="left" | Samoa | 61 | 2,944 | 178,631 | | align="left" | Wallis and Futuna (Fr.) | 57 | 274 | 15,585 | | align="left" | Norfolk Island (Aus) | 53 | 35 | 1,866 | | align="left" | Fiji | 47 | 18,270 | 856,346 | | align="left" | Cocos Islands (Aus) 1 | 45 | 14 | 632 | | align="left" | Palau | 42 | 458 | 19,409 | | align="left" | Solomon Islands | 17 | 28,450 | 494,786 | | align="left" | Vanuatu | 16 | 12,200 | 196,178 | | align="left" | New Zealand | 15 | 268,680 | 3,908,037 | | align="left" | Papua New Guinea | 11 | 462,840 | 5,172,033 | | align="left" | New Caledonia (Fr.) | 11 | 19,060 | 207,858 | | align="left" | Niue (N.Z.) | 8.2 | 260 | 2,134 | | align="left" | Christmas Island (Aus) 2 | 3.5 | 135 | 474 | | align="left" | Australia | 2.5 | 7,686,850 | 19,546,792 | | align="left" | Pitcairn Islands (UK) | 1.0 | 47 | 47 | | align="left" | Total | 3.7 | 8,523,655 | 32,642,390 | 1 Located in the Indian Ocean, not in Oceania.
