Sweden
The official language of Sweden is Swedish, a North Germanic language, related and very similar to Danish and Norwegian, but differing in pronunciation and orthography. Norwegians have little difficulty understanding Swedish, and Danes can also understand it, with slightly more difficulty than Norwegians. The same goes for standard Swedish speakers, who find it far easier to understand Norwegian than Danish. The dialects spoken in Scania, the southernmost part of the country, are influenced by Danish because the region traditionally was a part of Denmark and is nowadays situated closely to it. Sweden Finns are Sweden's largest linguistic minority, comprising about 5% of Sweden's population, and Finnish is recognised as a minority language. Owing to a recent influx of native speakers of Arabic in latter years, the use of Arabic is likely more widespread in the country than that of Finnish. However, no official statistics are kept on language use.
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".
