Elections to determine the makeup of the legislative bodies on the three levels of administrative division in the Kingdom of Sweden are held once every four years. At the highest level, these elections determine the allocation of seats in the Riksdag, the national legislative body of Sweden. Elections to the 20 county councils (landsting) and 290 municipal assemblies (kommunfullmäktige) – all using roughly the same electoral system – are held concurrently with the legislative elections on the second Sunday in September (with effect from 2014; until 2010 they had been held on the third Sunday in September).
