Languages of Sweden
The Language Law of 2009 recognizes Swedish as the "main" and "common" language of society as well as being the official language in "international contexts".
Swedish-speaking population of Finland
According to a sociological study published in 1981, the Swedish-speaking Finns meet the four major criteria for a separate ethnic group: self-identification of ethnicity, language, social structure, and ancestry. However, not all Swedish-speaking Finns are willing to self-identify as representatives of a distinct ethnicity. The major political organisation representing the Swedish-speakers in Finland, the Swedish People's Party, has defined the Swedish-speaking Finns as a people who express Finnish identity in the Swedish language. The issue is debated: an opposite view is still that the Swedish-speaking Finns are a sub-group of the ethnic Swedes, "östsvenskar" or "East Swedes".
