The number of public intermunicipal cooperation establishments (EPCIs) with their own tax system and the municipalities they group together has remained stable since 2017, as detailed in the May 2021 statistical information bulletin.(new window) of the ministerial statistical service of the General Directorate of Local Authorities (DGCL).
Stability of the number of EPCIs and their populations in 2021
The 1,253 EPCIs with their own tax system in 2021 bring together almost all the municipalities and the French population . Only four municipalities are not members of an EPCI with their own tax system. These are the four mono-communal islands which benefit from an exemption: the island of Yeu, the island of Bréhat, the island of Sein and the island of Ouessant.
The average population of EPCIs is divided by thirds between urban communities and metropolitan areas (34%), urban communities (34%) and communities of municipalities (32%).
In addition, the distribution by size of EPCIs with direct tax revenues (own tax regime) has been stable since 2017: 28% of EPCIs have less than 15,000 inhabitants and 10% more than 100,000 inhabitants.
Fewer inter-municipal unions
The number of municipal unions continues to decline at a rate of -4.2% (compared to -7% in 2017 and 2018), and the average number of municipalities that are members of a single-purpose (SIVU) or multiple (SIVOM) has been declining steadily for four years. A majority of unions have fewer than five member municipalities.
Linked to the number of municipalities and their population, unions are unevenly distributed across the territory. Appreciated in number of unions for 100 municipalities, the departments of Île-de-France and the Mediterranean coast such as the Rhône , Haute-Garonne and Gironde have a high number of unions . Other departments have a low number of unions compared to the number of their municipalities (such as Aube or Côte-d’Or ).
