MDI will create a population plan for Pirkanmaa region up to 2050 and a plan for all municipalities in the region up to 2040. The project will provide a detailed analysis of all the components of demographic development in the region and their dynamics in the 2010s, on the basis of which 3-4 population plans will be created. These population plans are described from the most optimistic and realistic development trend to a more pessimistic and realistic population trend. Population plans are created on the basis of each municipality’s own starting points. The population plan is used as a tool for the Pirkanmaa structural plan and the municipalities’ own strategies.
