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).
