Arrondissements of France

As of 2007-04-24there is a change in the HASC codes of 16 arrondissements. The purpose of this change is to ensure that no two arrondissements in the same region will have the same last two letters. This, in turn, is to pave the way to the possibility of changing the French divisions so that the regions, rather than the departments, become the primary subdivisions, while leaving the arrondissements as secondary subdivisions. (This is not to say that the change will definitely occur.)

France is divided into departments. There are regions, each of which comprises two or more departments. The regions have gradually been acquiring administrative functions since they were established in 1960, but I still consider the departments as the primary administrative subdivisions of France. The departments are divided into arrondissements. The arrondissements are further divided into cantons. The cantons, in general, are divided into communes. INSEE (Institut National de la Statistique et des Études Économiques) has download files of all of these divisions.

Most people who know Paris are aware that it's divided into 20 arrondissements. Oddly, the arrondissements of Paris are a different type of division from the arrondissements in this table. The 'arrondissements' of Paris, Marseille, and Lyon are just municipal divisions; those of Paris are properly considered cantons.

Change history:

The French encyclopedia, Quid, has much information about the change history of arrondissements. However, it omits certain details. For example, when two arrondissements merge, it only gives the name of the one that disappeared, not the one that engulfed it.

When Quid says that X was created, I think it means that X used to be a city other than the capital of an arrondissement. A new arrondissement was split off from the old one, with X as its capital. When A is substituted for B, I think that means that the capital of arrondissement A was moved from city A to city B, and consequently the name of the arrondissement was changed from A to B. When arrondissement T is eliminated, I think the arrondissement was merged with one or more of its neighbors.
