Caldoche is the name given to European inhabitants of the French overseas collectivity of New Caledonia, mostly native-born European origin French. The formal name to refer to this particular population is Calédoniens, short for the very formal Néo-Calédoniens, but this self-appellation technically includes all inhabitants of the New Caledonian archipelago, not just the Caldoche. Another "white" demographic element (although they may well be French people of different ethnic backgrounds) in the territory is expatriates from metropolitan France who live there temporarily as civil servants. Caldoches emphasise their own position as permanent locals by referring to the temporary expatriates as métros (short for métropolitains) or as Zoreilles (informally zozos) in local slang.
