Finland is officially bilingual, with Finnish and Swedish having mostly the same status at national level. Finland's majority population are Finns, whose mother tongue is either Finnish (approximately 95%), Swedish or both. The Swedish-speakers live mainly on the coastline starting from approximately the city of Porvoo (in the Gulf of Finland) up to the city of Kokkola (in the Bay of Bothnia). The Åland Islands, an autonomous province of Finland situated in the Baltic Sea between Finland and Sweden, are entirely Swedish-speaking. Children are taught the other official language at school: for Swedish-speakers this is Finnish (usually from the 3rd grade), while for Finnish-speakers it is Swedish (usually from the 3rd, 5th or 7th grade).
