Languages of Sweden
In 2009, the Riksdag passed the Language Law recognizing Swedish as the "main" and "common" language of society as well as being the official language in "international contexts", the five national minority languages, and Swedish sign language .
Swedish language
There is considerable migration between the Nordic countries, but owing to the similarity between the cultures and languages (with the exception of Finnish), expatriates generally assimilate quickly and do not stand out as a group. According to the 2000 United States Census, some 67,000 people over the age of five were reported as Swedish speakers, though without any information on the degree of language proficiency. Similarly, there were 16,915 reported Swedish speakers in Canada from the 2001 census. Although there are no certain numbers, some 40,000 Swedes are estimated to live in the London area in the United Kingdom. Outside Sweden and Finland, there are about 40,000 active learners enrolled in Swedish language courses.
