Île-de-France"le-de-France (/ˌiːl də ˈfrɒ̃s/, French: [il də fʁɑ̃s] (About this soundlisten); 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 $850 billion USD 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." - (en.wikipedia.org 09.10.2019) France Essonne Hauts-de-Seine Seine-Saint-Denis Seine-et-Marne Val-d'Oise Val-de-Marne Yvelines
