Tonga (Tongan: Puleʻanga Fakatuʻi ʻo Tonga), officially the Kingdom of Tonga, is a Polynesian sovereign state and archipelago comprising 177 islands with a total surface area of about 750 square kilometres (290 sq mi) scattered over 700,000 square kilometres (270,000 sq mi) of the southern Pacific Ocean, of which 52 islands are inhabited by its 103,000 people. Seventy percent of Tongans reside on the main island of Tongatapu.
Tonga stretches over about 800 kilometres (500 mi) in a north-south line – about a third of the distance from New Zealand to Hawaii. It is surrounded by Fiji and Wallis and Futuna (France) to the northwest, Samoa to the northeast, Niue to the east, Kermadec (part of New Zealand) to the southwest, and New Caledonia (France) and Vanuatu to the farther west.
