This list includes all Finnish cities and municipalities in which Swedish has official status at the local level.
In Finland 91.5% of the population speak Finnish, and 5.5% Swedish (as of December 31, 2006).[1] Both languages are official. At the local level, a municipality can officially use Finnish, Swedish or be bilingual. The Finnish language law provides for bilingualism if both languages represent at least 8% of the population, or at least 3,000 speakers. A previously bilingual municipality retains its status until the proportion falls below 6%, but a municipality can choose to retain bilingualism even if the percentage drops below 6.[2] Lohja is the only municipality to make use of this special provision. The 3,000-speaker rule was introduced as the proportion of Swedish residents of Turku (approximately 9,000 people) was less than 6%. Additionally, the 3,000-speaker rule applies in Vantaa (which has around 6,000 Swedish-speaking residents); other municipalities are bilingual by virtue of the percentage rule.
The language law does not apply in Åland (Ahvenanmaa in Finnish), an autonomous province that is monolingually Swedish.
Under the present regulations, valid until 2012, of 336 Finnish municipalities, 19 are Swedish-speaking (including 16 in Åland). 30 municipalities are bilingual; of these, 12 have a Swedish-speaking majority and 18 a Finnish-speaking one. The remaining 289 municipalities are monolingually Finnish-speaking.
Besides Åland, the Swedish-speaking areas are concentrated on the West Coast in Ostrobothnia, the South Coast regions of Uusimaa and Eastern Uusimaa, and the region of Finland Proper.
