Legal Populations — Municipalities and Municipal Arrondissements

The population data published by INSEE enter into force on 1 January; they are based on the administrative divisions as of 1 January of the previous year (N-1) and on the census for the year N-3. This dataset contains data on the legal populations of municipalities for the year 2020. These populations are available for the various administrative districts on 1 January of the year preceding the entry into force, within their territorial limits on that date: * [regions](https://public.opendatasoft.com/explore/dataset/demographyref-france-pop-legale-region-millesime/information/) * [departments](https://public.opendatasoft.com/explore/dataset/demographyref-france-pop-legale-departement-millesime/information/) * [cantons](https://public.opendatasoft.com/explore/dataset/demographyref-france-pop-legale-canton-millesime/information/) * **municipal municipalities and boroughs.** The results of the renovated censuses compare correctly with each other only over periods of at least 5 years apart.
