Official minority languages of Sweden
Finnish has been spoken in Sweden ever since the (then provincial) borders were drawn in the 13th century. Sweden has always had a significant migration to and from Finland. As the two languages belong to different language families it is easy to distinguish them, unlike the neighbouring languages Norwegian and Danish. The number of Finnish speakers in Sweden today has been estimated to over 460,000. Even though many current Swedes are of full or mixed Finnish descent, Swedish is the main language in practice for many bilinguals.
Swedish language
This type of classification, however, is based on a somewhat romanticized nationalist view of ethnicity and language. The idea that only rural variants of Swedish should be considered "genuine" is not generally accepted by modern scholars. No dialects, no matter how remote or obscure, remained unchanged or undisturbed by a minimum of influences from surrounding dialects or the standard language, especially not from the late 19th century onwards with the advent of mass media and advanced forms of transport. The differences are today more accurately described by a scale that runs from "standard language" to "rural dialect" where the speech even of the same person may vary from one extreme to the other depending on the situation. All Swedish dialects with the exception of the highly diverging forms of speech in Dalarna, Norrbotten and, to some extent, Gotland can be considered to be part of a common, mutually intelligible dialect continuum. This continuum may also include Norwegian and some Danish dialects.
