Title Polling Error in the 2015 UK General Election: An Analysis of YouGov’s Pre and Post-Election Polls
Year 2015
Access date 04.04.2016
The polls released by YouGov and all other pollsters prior to the 2015 UK general election significantly overestimated Labour support and underestimated Conservative support. For example, YouGov’s final pre-election poll, fielded 4–6 May and released on Wednesday afternoon on the eve of the election, had Labour and Conservatives tied at 34%. In fact, Conservatives won with 37.7% of the vote, well ahead of Labour at 31.2%. The purpose of this report is to understand why we were wrong and what could be done to fix it.
