Next Austrian legislative election

The 183 members of the National Council are elected by open list proportional representation at three levels; a single national constituency, nine constituencies based on the federal states, and 39 regional constituencies. Seats are apportioned to the regional constituencies based on the results of the most recent census. For parties to receive any representation in the National Council, they must either win at least one seat in a constituency directly, or clear a 4 percent national electoral threshold.[1]

Following the elections, seats are allocated to the candidates of successful parties and lists in a three-stage process, starting with the regional constituencies. Seats are distributed according to the Hare quota in the regional constituencies, and with unallocated seats distributed at the state constituency level.[2] Any remaining seats are then allocated using the D'Hondt method at the federal level, to ensure overall proportionality between a party's national vote share and its share of parliamentary seats.[3]

In addition to voting for a political party, voters may cast three preferential votes for specific candidates of that party, but are not required to do so.[4] These additional votes do not affect the proportional allocation based on the vote for the party or list, but can change the rank order of candidates on a party's lists at the federal, state, and regional level. The threshold to increase the position of a candidate on a federal party list is 7 percent, compared to 10 percent at the state level, and 14 percent at the regional level. The names of candidates on regional party lists are printed on the ballot and can be marked with an "x" to indicate the voter's preference. Preference votes for candidates on party lists at the state and federal level, however, must be written in by the voter, either by writing the name or the rank number of the candidate in a blank spot provided for that purpose.[5]
