Error = average − result, in percentage points. A dash means the party or candidate was missing from the average or the result; it is left out of both errors.
Polling trend
The average of recent polls. Newer polls and more accurate pollsters count more. How it’s calculated
Latest polls
Each poll as published, with its pollster, fieldwork dates, sample size and a link to the source.
How to read a poll
- Sample size is how many people were asked. More people means less random error, never none.
- ±3 is the margin of error: the real figure is likely within 3 points either way of the one shown.
- Two polls can differ because they were taken on different dates, with different methods and different samples.
- est. means the institute did not publish a margin of error, so it is estimated from the sample size.
- The average smooths this out: it combines recent polls, so one unusual poll cannot swing the picture.
