We invite you to investigate the voting behavior in Austria over the last 100 years. Select a year to get started.
1933–1938 Dollfuß-Schuschnigg dictatorship
After the elimination of parliament in 1933, the Republic of Austria was rebuilt into a dictatorship. The 1934 adopted constitution abolished the National Council officially, it was therefore not elected.
1938–1945 NS-regime in Austria
1938 Austria was incorporated into the National Socialist German Reich. During the Nazi regime, no democratic elections were held. The parliament building on Vienna's Ringstraße was taken over by the NSDAP and used for the administration and representation of the party. After the liberation in 1945, the first task of a provisional government, together with the Allied administration, was to prepare the first National Council elections of the Second Republic.
The SORA Institute, known for precise extrapolations and election analyzes since 1994, invites you to take a closer look at voting behavior in Austria over the last 100 years. Here you can view the results of the voter stream analysis for all previous National Council elections. Starting with the election to the Constituent National Assembly in 1919, they give a detailed insight into the voting behavior and the dynamics of the respective time, embedded in essential political events:
Here you can find more details on how SORA calculates such voter flows.

Voter transition analysis show the changes in voters' decisions compared to the previous election. They represent the migrations of voters between candidate parties - or of or to the group of non-voters. So it becomes visible:
Analysis without survey data
SORA voter transition analysis are based on “aggregate data”, ie on the results of districts, municipalities, etc. The statistical relationships calculated there are used to deduce the behavior of the voters.
This is something like this: If a party in the current election on average in exactly those communities is strong in which another party in the comparison was strong, interpreted SORA as an indication that many voters have changed between these parties.
Method of calculation
The procedure for this is based on probability calculation and is called multiple regression: “regression”, because the party results of the current election are attributed to the party results of the comparison vote (regressed). “Multiple” because SORA relates the current election results of one party to the results of all parties to the comparison.
The equation for a voter transition analysis of the national election 2008 for the national election 2013 looks like this for the SPÖ 2013:
SPÖ2013 = b1 × SPÖ2008 + b2 × ÖVP2008 + b3 × FPÖ2008 + b4 × BZÖ2008 + b5 x Grüne2008 + b6 × Other-parties2008 + b7 × Non-voters2008.
With regard to demographic changes, it is assumed for the calculation that the persons entitled to vote remain the same, ie. Additions by immigration and first-time voters are equated with departures by removal and deceased. Differences in the number of eligible voters between the two election years considered are compensated by the number of non-voters. If the number of eligible voters increases, these “new” voters in the comparison are considered non-voters.
Extrapolation
The SORA extrapolation, the assessment of pre-election results, is also based on voter transistion analysis. By means of the voter inflows, which are calculated on the basis of the counted votes, SORA closes on the overall result.
Behind this is the assumption that trends in socially similar sprinkles will be similar. In the run-up to the election, therefore, similar groups of parishes must be identified in which comparable voter movements can be expected on election day.
Due to the electoral secrecy voter transistion analyzes can not be validated later. However, comparative studies with so-called exit polls, ie polls after a poll, showed that the described method based on aggregate data is very reliable.
