About this election
How the vote works
The Riksdag is a unicameral parliament of 349 members elected for fixed four-year terms by party-list proportional representation. Seats are allocated by the modified Sainte-Laguë method across 29 multi-member constituencies, with 310 fixed constituency seats topped up by 39 nationwide adjustment seats (utjämningsmandat) that make the overall result almost perfectly proportional. To share in the seats a party must clear a 4% national threshold (or 12% in a single constituency). Voting is administered by the Election Authority (Valmyndigheten), and the regional (region) and municipal (kommun) councils are elected on the same day, making it a single national polling day every four years.
