New Caledonia (; French: Nouvelle-Calédonie) is a sui generis collectivity of overseas France in the southwest Pacific Ocean, south of Vanuatu, about 1,210 km (750 mi) east of Australia, and 17,000 km (11,000 mi) from Metropolitan France. The archipelago, part of the Melanesia subregion, includes the main island of Grande Terre, the Loyalty Islands, the Chesterfield Islands, the Belep archipelago, the Isle of Pines, and a few remote islets. The Chesterfield Islands are in the Coral Sea. French people, especially locals, call Grande Terre "Le Caillou" ("the pebble").New Caledonia has a land area of 18,576 km2 (7,172 sq mi) divided into three provinces. The North and South Provinces are on the New Caledonian mainland, while the Loyalty Islands Province is a series of three islands off the east coast of mainland. New Caledonia's population of 271,407 (October 2019 census) is of diverse origins and varies by geography; in the North and Loyalty Islands Provinces, the indigenous Kanak people predominate, while the wealthy South Province contains significant populations of European (Caldoches and Metropolitan French), Kanak, and Polynesian (mostly Wallisian) origin, as well as smaller groups of Southeast Asian, Pied-Noir, and North African heritage. The capital of New Caledonia is Nouméa.
