The FinnishEduskunta, or Parliament, is made up of 200 members, elected from 15 separate geographic areas, or electoral districts. All of the constituencies, with the exception of Åland, elect multiple members, ranging between six and 35 depending on the constituency's population. The constituency division is based on the old (1634–1997) provinces of Finland, and has remained more or less the same since the first elections for the Eduskunta in 1907.
A special case is the constituency of Åland, which only elects one member of parliament. Even though the region of Åland is much smaller than any of the other constituencies, Finnish law gives a special status for the region and it gets a seat even if its population would not entitle it to one.
