Twenty-one of these make up continental France, another is the island of Corsica, off the coast of the mainland, and the remaining five are overseas territories. Ile-de-France is the most populous of these regions, with a population of about 12 million. More people live in this area than in some European countries, such as Austria or Norway. It is the richest region of France.
