An agglomeration community (French: communauté d'agglomération, pronounced [kɔmynote daɡlɔmeʁasjɔ̃]) is a consortium of communes (municipalities) in France, created as a government structure by the Chevènement Law of 1999.
It is one of four forms of intercommunality, less integrated than a métropole or a communauté urbaine but more integrated than a communauté de communes.
[1] The population (as of 2017) of the agglomeration communities ranges from 355,650 inhabitants (CA Grand Paris Sud Seine-Essonne-Sénart) to 29,289 inhabitants (CA Grand Verdun).
Several former communautés d'agglomération have been converted into communautés urbaines or métropoles, for instance those of Strasbourg, Rouen, Saint-Étienne and Caen.
The table below lists the communautés d'agglomération with more than 200,000 inhabitants (as of 2021).
