The communes of France are the smallest administrative divisions in the country, serving as the basic units of local government. There are over 35,000 communes, each with its own mayor and council, responsible for local services such as education, transportation, and urban planning. Communes can vary significantly in size and population, ranging from bustling cities like Paris to small rural villages. They play a crucial role in the French administrative system, allowing for localized governance and community engagement in decision-making processes.
