Located in Oceania, Tonga is an archipelago in the South Pacific Ocean, directly south of Western Samoa and about two-thirds of the way from Hawaii to New Zealand. Its 176 islands, 36 of them inhabited, are divided into three main groups – Vava'u, Ha'apai, and Tongatapu – and cover an 800-kilometre (500-mile)-long north-south line.
The island of 'Eua, a 10-minute flight away from Tongatapu, has a blend of modern comfort (the island has one hotel and a motel) and the traditional South Sea island lifestyle. Many species of exotic bird live on the island.
The population of Tonga is 106,146 (July 2011 est.). 37.2% are under 15, 56.7% 15 to 64, and 6.1% over 64. The birth rate is 24.7/1000, the death rate is 4.88/1000, and the net migration rate is -17.9/1,000.
