Arrondissements of France

Structure and administration

Each arrondissement contains a collection of communes and is usually further organised into cantons for electoral purposes. The capital of a department, called the prefecture, sits in one arrondissement; other arrondissements are administered from a subprefecture. The state representative who leads an arrondissement is the subprefect (sous-préfet), who reports to the departmental prefect. Unlike departments and communes, arrondissements do not have an elected council.

Key characteristics

• Number and size vary: most departments have three or four arrondissements, though some have only one and others more.
• They perform administrative tasks such as coordinating national services, civil registration, and issuing certain permits.
• The arrondissement that contains the department capital is also the seat of the prefect; other seats are called subprefectures.

History and development

The arrondissement as an administrative layer dates to reforms made after the French Revolution and was consolidated under the Consulate around 1800. Its role and number have evolved with territorial reforms, with periodic adjustments to meet demographic and administrative needs. The modern map reflects these historical reorganisations while remaining subordinate to departments and communes.

Uses, distinctions and notable facts

Arrondissements are important for state presence and statistical reporting but are not self-governing. They must be distinguished from municipal arrondissements found within large cities: Paris, Lyon and Marseille are divided into municipal arrondissements that are subdivisions of a single commune and have different functions and local representation.
