Regions in France Hauts-de-France, in the northern part of the country, and Provence-Alpes Côte d’Azur in the southeastern part, were the second and the third most densely populated regions in Metropolitan France. The French southeastern coast is known for being highly urbanized, while its living conditions (sun, Mediterranean sea…) make it one of the most attractive region to work and live in France. Hauts-de-France, which used to be one of the leading industrial regions of the country, now benefits from its geographical proximity to the heart of Europe: Brussels. Furthermore, rural regions like Centre-Val de Loire or Bourgogne Franche-Comté are less populous, and the share of the rural population in France is decreasing for years now.
