For elections to the Riksdag, regional assemblies and municipal assemblies, there shall be geographically defined areas for which members shall be elected for the decision-making assembly to which the election relates (constituencies). Sweden constitutes a single constituency for elections to the European Parliament.
Unless otherwise provided, when applying this chapter the number of persons entitled to vote in an election shall be estimated on the basis of the information contained in the population registration database under the Act on the Processing of Personal Data in the Swedish Tax Agency’s Population Registration Activities (2001:182) on 1 March of the election year.
