Statistics Finland receives information on the changes in place of residence that involve a permanent change of domicile. These changes in domicile are classified at Statistics Finland into intramunicipal moves and intermunicipal moves. Intramunicipal moves consist of moves from one dwelling to another within the same municipality, with moves from one building or house to another forming a separate sub-category. Intramunicipal statistics dating to 1986 and earlier cover only moves from one building or house to another within the same municipality.
Until 1993, the concept of intramunicipal migration consisted of moves from one private dwelling unit to another within the same municipality. Since 1994, intramunicipal moves from institutional dwellings to private dwellings and vice versa have been included in the data. Moves from a situation where there is no permanent dwelling to private dwellings and vice versa have been classified as intramunicipal migration since 1994. This change in the concept has resulted in an increase of about 6 per cent in the intramunicipal migration data.
When the data for 1993 were produced, the statistical period was also changed from the period of 2 January to 1 January into 1 January to 31 December because of the corresponding change in the Population Information System. In the transition year the statistical period fell one day short of one year (the effect being 11,000 cases of intramunicipal migration and 4,500 cases of intermunicipal migration).
The coming into force of the Act on the Municipality of Domicile has somewhat increased the volume of intramunicipal and intermunicipal migration in 1994 and after that.
