A year ago the polls got the general election wrong. This week YouGov was the only company to carry out polls for all three of the London, Scottish and Welsh votes. Following both our own internal investigation and the British Polling Council enquiry, we have changed our sampling so as to more accurately reflect the make-up of the electorate.
Based on the first real-time test of these new approaches that yesterday’s elections offered, it is clear that our new sampling methods have notably increased the accuracy of our results. CONT.
