Frequently asked questions about opinion polls
- What does the change in percentage points mean?

Opinion polls are published regularly, often every or every other month depending on the institute. - What is the parliamentary threshold?
The parliamentary threshold is 4 %. Parties receiving less than this typically do not gain seats in parliament. - How is the margin of error interpreted?
The margin of error indicates the uncertainty in the results. Small differences between parties may fall within the margin of error and should be interpreted cautiously. - What is the difference between voter support and mandates?
