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-speaking population of Finland
Following an educational reform in the 1970s, both Swedish and Finnish became compulsory school subjects. The school subjects are not called "Finnish" or "Swedish"; the primary language in which lessons are taught depends upon the pupil's mother tongue. This language of instruction is officially and in general practice called the "mother tongue" (' in Finnish, ' in Swedish). The secondary language, as a school subject, is called the "other domestic language" (' in Finnish, ' in Swedish). Lessons in the "other domestic language" usually start in the third, fifth or seventh form of comprehensive school and are a part of the curriculum in all secondary education. In polytechnics and universities, all students are required to pass an examination in the "other domestic language" on a level that enables them to be employed as civil servants in bilingual offices and communities. The actual linguistic abilities of those who have passed the various examinations however vary considerably.
