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.
Nordic Council
The Nordic Council uses the three Continental Scandinavian languages (Danish, Norwegian, and Swedish) as its official working languages, but also publishes material in Finnish, Icelandic, and English for information purposes. The council refers to Danish, Norwegian, and Swedish collectively as Scandinavian and considers them to be different forms of the same language forming a common language community. Since 1987, under the Nordic Language Convention, citizens of the Nordic countries have the opportunity to use their native language when interacting with official bodies in other Nordic countries without being liable to any interpretation or translation costs. The Convention covers visits to hospitals, job centres, the police and social security offices. The languages included are Swedish, Danish, Norwegian, Finnish, and Icelandic.
