Even if you are not a Swedish citizen, you can still participate in elections.
1. Municipal Elections (kommunvalet)
2. County Elections (landstingvalen)
You can vote in the municipal and county council elections if you are: an EU citizen or a citizen of Iceland or Norway and you are registered in the municipality or county concerned; or a citizen of a country other than EU/Iceland/Norway and you have been registered in Sweden for 3 consecutive years before the day of the elections
3. EU Elections (Europavalen)
If you are an EU national living in another EU country, you have the right to vote and stand as a candidate in European elections in that country. To vote in the European elections, you must be an EU citizen registered in Sweden 30 days before the elections. You must also inform the county authority (länstyrelse) that you wish to vote in Sweden rather than in the country of which you are a citizen.
4. The Church of Sweden Elections (Kyrkoval i Svenska kyrkan)
If you are a member of The Church of Sweden, have a residence in Sweden, and you are older than 16, you can participate in the church elections.
5. Various associations elections
Maybe you do not find you trade union (fackförening) or your housing cooperative (bostadsrättsförening) so important, but many Swedes do. Every election matters!
