In the 1940s, 70,000 young Finnish children were evacuated from Finland. Most of them came to Sweden during the Winter War and the Continuation War, and around 20% remained after the war. Helped by the Nordic Passport Union, Finnish immigration to Sweden was considerable during the 1950s and 1960s. In 2015, Finnish immigrants to Sweden made out 156 045 persons (or 1.58% of the Swedish population) Not all of them, however, were Finnish speakers. The national minority of Sweden Finns usually does not include immigrated Swedish-speaking Finns, and the national minority of Sweden Finns is protected by Swedish laws that grant specific rights to speakers of the Finnish language. English somewhat lacks the distinction between Finns in Sweden (), which emphases nationality rather than linguistic or ethnic belonging and thereby includes all Finnish heritage regardless of language, and Sweden Finns () which emphases linguistic and ethnic belonging rather than nationality and usually excludes Swedish-speaking Finns. Such distinctions are, however, blurred by the dynamics of migration, bilingualism, and national identities in the two countries. Note that speakers of Meänkieli are singled out as a separate linguistic minority by Swedish authorities.
