Administrative divisions of France

The administrative divisions of France are concerned with the institutional and territorial organization of French territory. These territories are located in many parts of the world. There are many administrative divisions, which may have political (local government), electoral (districts), or administrative (decentralized services of the state) objectives. All the inhabited territories are represented in the National Assembly, Senate and Economic and Social Council and their citizens have French citizenship and elect the President of France.
The French Republic is divided into 18 regions: 12 in mainland France and 6 elsewhere (1 in Europe: Corsica; 2 in the Caribbean (the Lesser Antilles): Guadeloupe and Martinique; 1 in South America: French Guiana; and 2 in the Indian Ocean near East Africa: Mayotte and Réunion). They are traditionally divided between the metropolitan regions, located on the European continent, and the overseas regions, located outside the European continent. Both have the same status and form the most integrated part of the French Republic.
As of 1 January 2022, metropolitan France is divided into the following:
Furthermore, as of January 2009, there exist 2,585 intercommunal structures grouping 34,077 communes (93.2% of all the communes of metropolitan France), with 87.4% of the population of metropolitan France living in them. These intercommunal structures are:
Five overseas regions (régions d'outre-mer, or ROM), which have the same status as metropolitan regions. The overseas regions are as follows:
The French Republic includes five overseas collectivities (collectivités d'outre-mer, or COM) with a semi-autonomous status:
The French Republic includes one autonomous collectivity:
New Caledonia's status is unique in the French Republic: it is the only French local government that is not a territorial collectivity (although its subdivisions are territorial collectivities). It is regarded as a sui generis collectivity, which means that local government and parliament have the power to pass and enforce specific laws without seeking the consent of the French Government; unless such laws are declared illegitimate by the Constitutional Council in a specific proceeding brought to the Constitutional Council. As agreed in the 1998 Nouméa Accord, a New Caledonian citizenship was established (in addition to the French citizenship which is kept in parallel, along with the consequent European citizenship) and a self-determination referendum was held in 2018. Two follow-up referendums were held in 2020 and 2021.
These territories have no permanent civilian population. The residents consist of military personnel, scientific researchers, and support staff.
1 overseas territory (territoire d'outre-mer, or TOM): the French Southern and Antarctic Lands, which have no permanent population and no communes.
French subdivisions that have a (limited) freedom of administration are called territorial collectivities. Among them are regions, departments, communes, overseas collectivities, provinces (only present in New Caledonia), and the territorial collectivity of Corsica which belongs to no category (but is usually grouped with the regions). New Caledonia is unique as it is not a territorial collectivity.
Citizens from all parts of France, including the overseas administrative divisions, vote in national elections (presidential, legislative), and all of the collectivities are represented in the Senate.
Some areas are the clear responsibility of one level of government (e.g. the state is responsible for international issues), but in other areas it is shared across some or all levels of government (e.g. transport, parks, tourism, culture, and sport get different types of support from different levels).
Historically, France was divided into a complex mosaic of more or less independent entities. Their gradual incorporation into France as provinces may be followed in the article Territorial formation of France.
