The Austrian People's Party (ÖVP) regained the absolute majority it had lost in 1999, achieving a strong swing of 9 percentage points.

The Freedom Party of Austria (FPÖ) lost more than half its vote share and seats, falling to third place behind the Social Democratic Party of Austria (SPÖ), which gained four points.

The repeal of compulsory voting resulted in a huge decline in voter turnout, which fell from 87% to 60%.

The 36 seats of the Landtag of Vorarlberg are elected via open list proportional representation in a two-step process.

For parties to receive any representation in the Landtag, they must either win at least one seat in a constituency directly, or clear a 5 percent state-wide electoral threshold.
