Migration has played an important role in shaping Finnish society throughout its history. Notable instances are the [[Forest Finns|Forest Finns']] migration to Sweden during the 15th century and the relocation of [[Ingrian Finns|Ingrians]] to the present-day St Petersburg region during the 17th century. Changes in borders resulted in the formation of Finnish settlements outside its territory. Wars and political conflicts led to massive population movements, such as the [[Evacuation of Finnish Karelia|Karelian evacuation]] during World War II, which exiled roughly 420,000 individuals within Finland's borders.<ref name="siirtolaisinstituutti-internal-migration">{{cite web |url= https://siirtolaisuusinstituutti.fi/en/research/internal-migration/ |title= Internal Migration |publisher= The Migration Institute of Finland |language=en |access-date= 6 October 2023}}</ref>

Until the 1960s, Finland was predominantly an agricultural society. However, waves of urbanization and political transitions have contributed to migration movements. Currently, [[urbanization]] continues to be a significant internal migration pattern, with growth centers and sparsely populated regions. Approximately 250,000 people, mainly young adults, make annual municipal moves, which have notable implications for regional development in the 21st century.<ref name="siirtolaisinstituutti-internal-migration"/>
