Île-de-France (/ˌiːl də ˈfrɒ̃s/, French: [il də fʁɑ̃s] (listen); literally "Island of France") is the most populous of the 18 regions of France. It is located in the north-central part of the country and often called the région parisienne ("Paris Region") because it includes the city of Paris. Île-de-France is densely populated and economically important: it covers only 12,012 square kilometres (4,638 square miles), about 2% of France's territory, but has an official estimated population of 12,213,364 (18.2% of the population of France) and accounts for nearly 30% of the French Gross Domestic Product (GDP). The region is made up of eight administrative departments: Paris, Essonne, Hauts-de-Seine, Seine-Saint-Denis, Seine-et-Marne, Val-de-Marne, Val-d'Oise and Yvelines. It was created as the "District of the Paris Region" in 1961 and renamed in 1976 after the historic province of Île-de-France, when its status was aligned with the other French administrative regions created in 1972. Residents are sometimes referred to as Franciliens, an administrative word created in the 1980s. The GDP of the region in 2016 was €681 billion (or US$850 billion at market exchange rates). It has the highest per-capita GDP among regions in France and the third-highest of regions in the European Union. In 2018, almost all of the twenty-eight French companies listed in the Fortune Global 500 had their headquarters in the Paris Region. Besides the landmarks of Paris, the region has many important historic sites, including the Palace of Versailles and the Palace of Fontainebleau, as well as the most-visited tourist attraction in France, Disneyland Paris. The poverty rate in Île-de-France was 15.9% in 2015, compared with 12.3% in 2006. The region is also increasingly unequal. Housing prices have pushed the less affluent outside Paris.
