List of municipalities of Finland in which Finnish is not the sole official language

[4] Officially, a municipality is bilingual if the minority language group consists of at least 8% of the population, or at least 3,000 speakers.

[5] Municipalities that make use of the 3,000-speaker rule include the national capital Helsinki and the cultural center of Swedish Finns, Turku.

On the Åland archipelago, where Finnish is almost absent from daily life, the language law does not apply.

[7][1] Four municipalities, all located in Lapland, have a Finnish-speaking majority and a Sami-speaking minority: Enontekiö, Inari, Sodankylä and Utsjoki.

[2] Initially, only Swedish was accorded official bilingualism, through a language act of 1922;[5] similar provisions were extended to Sami through a 1991 law.
