Constituencies of Finland

There are thirteen constituencies in Finland. The citizens of each constituency elect members of the Parliament of Finland, ranging from 6 to 35 per constituency, except for 05 Åland, which only elects one. The constituency division is based on the province division in use from 1634 to 1997, and has remained basically the same since the first parliamentary election, which was held in 1907. In 1939, the constituency of Northern Oulu was divided between the constituencies of Lapland and Oulu. The constituency of Southern Oulu was renamed to Oulu in the process. After the Continuation War, the electoral districts of Eastern and Western Viipuri, which lost much of their territories to the Soviet Union, were united to 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.
