Each dataset consists of 2 classes of entities: * the refined distribution of the population to the built (polygons) * the refined distribution of the population to the centroid of the frame (punctual) The treatment is carried out from several data sources: * the IRIS GE INSEE population — 2018 (Latest year, production is n-3 compared to the current year) * CEREMA land files — 2021 (the Cerema land file vintage of year n is based on the MAJIC vintage of year n and the MAJIC data of this vintage returns the data for the year n-1) * the BDTopo IGN — 2021 * the Parcellaire Express IGN — 2021 ***We we worked with the most recent vintage on the population (2018) which does not match the IGN and Cerema data vintage (2021). It should therefore be borne in mind that this data does not show the actual distribution in 2018 but a potential distribution on the plots and buildings of the year 2020 (FF n-1).*** The sub-communal population is distributed in proportion to the living area of the plots. It is then ventilated on the significant buildings of each plot. The entire treatment is described in the methodology that accompanies the data. OPenIG, co-producer of the data, participated in specifications, industrialisation of the processing chain and the dissemination of entity classes. ** Warning** The operations that may be made of this data will be the sole responsibility of the user. It does not in any way provide the actual, exact or legal distribution of the population at the level of the building or parcel. Thus, use on this scale makes no sense (e.g. distribution of the population on the buildings of the same plot) as well as possible calculations of evolution between two dates. **Authors:** Montpellier Méditerranée Métropole, City of Montpellier, OPenIG ** Covered territory:** The data is delivered at the level of the Occitanie region.
