1934 Icelandic parliamentary election

In the previous election, the 28 members of the Lower House Althing had been elected in one- or two-member constituencies by plurality voting, except in Reykjavík, where the four seats were elected by proportional representation. Eight members of the Upper House were elected at the same time as the Lower House, whilst the remaining six members were elected in separate national elections using proportional representation.[2]

The reforms raised the number of seats in the Lower House to 33, of which 11 were to be compensatory seats. The compensatory seats were awarded to parties which had won at least one of the 22 standard seats, and were allocated according to their votes received divided by the seats they had won.[3] Once allocated to a party, the seats were then allocated based on a preferential basis:[3]

1. The party's candidate who had won the highest number of votes in a constituency, but was not elected.
2. The party's candidate who had won the highest percentage of the votes in a constituency, but was not elected.
3. The top candidate on a party's nationwide list (if they had used one).
4. The party's candidate with the second highest number of votes in a constituency, but was not elected.

Although a party could only have one compensatory seat in each constituency, this still left some constituencies over-represented.[3]

All seats in the Upper House seats were now elected at the same time as the Lower House, whilst the number was increased from 14 to 16.[4] In Reykjavík the number of seats was increased from four to six, with a subsequent lowering of the threshold to win a seat in the city. The voting age was lowered to 21, and those receiving poor relief were able to vote for the first time.[3]
