DeSO - Demographic Statistical Areas WMS

DeSO - Demographic statistical areas is a nationwide classification created by Statistics Sweden that came into force in January 2018. A new version was published in 2025. DeSO divides Sweden into 6,160 areas where most areas have a population between 700 and 3,000 inhabitants. The division follows the county and municipal boundaries that applied at the time of publication. DeSO does not have denominations or names, but is described by a code with nine unique positions. The first four consist of the county and municipality code and point out the county and municipality in which the area is located. The fifth position indicates which category the area belongs to A, B or C. A are areas that are largely outside major population concentrations or agglomerations. B are areas that are mostly in population concentrations or agglomerations but are not a central city. Category C is the area that is mostly located in the municipality's central city. The three subsequent positions consist of a sequential number that sorts the areas geographically. This sorting is based on the categories and starts in the south and continues north. The last position is a backup site that will be used in case a DeSO in the future needs to be split. A DeSO can only occur in one location.
