Île-de-France is a French region centred on Paris, its prefecture, and made up of eight departments: Paris, Seine-et-Marne, Yvelines, Essonne, Hauts-de-Seine, Seine-Saint-Denis, Val-de-Marne and Val-d'Oise. Paris holds a distinct status of its own: both a commune and a department since 1977, it is governed by a single Conseil de Paris, unlike the seven other, ordinary-law Île-de-France departments. The region covers about 12,011 square kilometres and comprises close to 1,270 communes with about 12.4 million inhabitants, known as Franciliens, making it the most populous and most densely populated region in France. Its territory combines a dense urban core with extensive farmland and forests on its outskirts, notably in the Brie, Beauce and Vexin areas.
