Cantons of France
As of 2015, there are 2,054 cantons in France.
Most of them group together some communes (the lowest administrative division of the French Republic), although larger communes may comprise several cantons, since the cantons are intended to be roughly equal in population – unlike the communes, which range from more than two million inhabitants (Paris) to just one person (Rochefourchat).
