Constituencies of Finland
There are 13 constituencies in Finland or electoral districts for elections to the Finnish Parliament.[1] Each electoral district elects a number of MPs proportional to its population, currently ranging from 6 to 35 MPs, except Åland which only elects one.
Boundaries
The boundaries of the electoral districts are based on the provinces in use from 1634 to 1997, and have remained largely the same since the first parliamentary election in 1907. Some minor border changes between the regions of Finland have affected the electoral districts, but there have also been larger changes, detailed below.
In 1939, the constituency of Northern Oulu was divided between the constituencies of Lapland and Oulu, and the constituency of Southern Oulu was renamed to Oulu. After the Continuation War, the electoral districts of Eastern and Western Viipuri, which lost much of their territories to the Soviet Union, were united into the new constituency of Kymi. At the same time, Åland became a distinct constituency. In 1954, Helsinki was cut from the constituency of Uusimaa. In 1962, the southern and northern Vaasa constituencies were united. In 2015, the constituencies of Kymi and Southern Savonia were united, forming the constituency of South-Eastern Finland; similarly, the constituencies of Northern Savonia and North Karelia were united to form the constituency of Savonia-Karelia.
