Data paper : Les communes nouvelles françaises (2012-2022) : une méthode pour l’analyse de données à l’échelon municipal selon des limites évolutives

This data paper presents the creation of a database bringing together all the French municipalities while giving a specific place to those which have undergone a merger process between 2012 et 2022: "the new municipalities" (communes nouvelles). Potential data gap and consistency issues arise with the creation of these new territorial entities aggregating municipal mergers. Using data from official statistics (INSEE - National Institute for Statistics and Economic Studies - and IGN - National Geographic Institute), this paper describes a process of compilation and aggregation of data. The method is detailed here, to allow its reproducibility.
