A number of newspapers and think-tanks commission opinion polls to predict which way people are likely to vote in upcoming elections.
Opinion polls also help economists and marketeers estimate trends and behaviours before they happen. However, as was demonstrated all too clearly in 2016, the polls can get it wrong.
If you believed the polls in 2016, Britain would still be in the European Union and Hilary Clinton would be the President of the United States. Of course neither of these eventualities came true, so it’s certainly worth taking poll data with a pinch of salt.
Each polling agency asks slightly different questions.
The 2017GeneralElection.uk Aggregate Poll is the mean average of all polling data recorded in the current calendar month. Comparisons are against previous month’s aggregate data.
