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 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.
Tonga is lively well into the evening, generally becoming suddenly very quiet at around 23:00. Expect to see people walking around until late. Beer and liquor are available from many outlets, including Fijian, Australian and New Zealand imports to complement the local brews. If you are keen to check out native drink, try Kava (something like liquid novacaine) at least once.
