Demography

With an estimated population of 64.5 million people, France is the 19th most populous country in the world. France's largest cities are Paris, Marseille, Lyon, Lille, Toulouse, Nice, and Nantes.

France is divided into 26 administrative regions. 22 are in metropolitan France, and four are overseas regions. The regions are further subdivided into 100 departments which are numbered (mainly alphabetically). This number is used in postal codes and vehicle number plates amongst others. Four of these departments are found in the overseas regions and are simultaneously overseas regions and overseas departments and are an integral part of France (and the European Union) and thus enjoy a status similar to metropolitan departments.
