Statistical grouping of municipalities 2021
The statistical grouping of municipalities is a classification developed by Statistics Finland for describing the degree of urbanisation and it has been in use since 1989. It divides municipalities by the proportion of the population living in urban settlements and by the population of the largest urban settlement into urban, semi-urban and rural municipalities. It is used both as the regional division of statistics compilation and in chargeable special surveys.
An urban settlement is not dependent on administrative regional divisions, so it can stretch over the area of several municipalities.
Starting from 24 October 2011, the statistical grouping of municipalities is based on the definition of urban settlements made once a year and on data thus obtained about the population living in urban settlements.
The concept of urban settlement: An urban settlement is a cluster of dwellings with at least 200 inhabitants. The definition of urban settlement is based on the definitions made by the Finnish Environment Institute with geographic information methods utilising the building and population data of Statistics Finland's 250m x 250m grid data. The number of buildings in grids containing buildings and their neighbouring grids, as well as the floor area of buildings are reviewed in the definition. From the uniform clusters of dwellings generated in the defining stage, the ones with at least 200 inhabitants are selected.
