The 101 French departments are divided into 342 arrondissements, which may be roughly translated into English as districts. The capital of an arrondissement is called a subprefecture. When an arrondissement contains the prefecture (capital) of the department, that prefecture is the capital of the arrondissement, acting both as a prefecture and as a subprefecture. Arrondissements are further divided into cantons and communes.
A municipal arrondissement (French: arrondissement municipal, pronounced [aʁɔ̃dismɑ̃ mynisipal]), is a subdivision of the commune, used in the three largest cities: Paris, Lyon, and Marseille. It functions as an even lower administrative division, with its own mayor. Although usually referred to simply as an "arrondissement," they should not be confused with departmental arrondissements, which are groupings of communes within one département. The official translation into English is "district".
Belgium is a federalized country which geographically consists of three regions, of which only Flanders (Flemish Region) and Wallonia (Walloon Region) are subdivided into five provinces each; the Brussels-Capital Region is neither a province nor is it part of one.
In Belgium, there are administrative, judicial and electoral arrondissements. These may or may not relate to identical geographical areas.

Most nations in Africa who have been colonised by the French have retained the arrondissement administrative structure. These are normally subunits of a Department, and may either contain or be coequal with Communes (towns). In Mali the arrondissement is a subunit of a Cercle, while in some places arrondissements are essentially subdistricts of large cities.
