Folketing elections were held in Denmark on 22 April 1918,[1] the first in which women could vote. The result was a victory for Venstre, which won 45 of the 140 seats in the Folketing, which had been expanded from 114 to 140 seats. Voter turnout was 75.5%.[2]
Of the 23 leveling seats, twenty (nine in the islands and eleven in Jutland) were allocated on a regional basis, and three (one in the islands and two in Jutland) were allocated based on the nationwide vote (including Copenhagen).[3] The allocation of candidates to leveling seats was based on a best-loser rule, using a form of Scorporo; in each single-member constituency a Hare quota of votes for the appropriate region was subtracted from the winner's votes and the remainders were pooled at a county level. The candidates with the highest proportion of the votes relative to the region's Hare quota were allocated the leveling seats.[3]
The 1918 elections were the only ones in Danish history to feature this mixed system.[4][5] Future elections would be entirely using proportional representation with the single-member districts not affecting the party-level results.
