EU referendum voting intentions, Sep 2015 - Jun 2016

Our ‘poll of polls’ polling model is an amended seven point rolling average of all EU referendum voting intentions surveyed in the run up to June 23 by pollsters with British Polling Council membership. The rolling average involves modification so to remove the potential over-saturation of frequent pollsters at certain points in time. One data point, for example, will not be taking into account five YouGov polls, one Ipsos Mori and one Survation, but instead an average of those five YouGov polls, one Mori, one Survation, and so forth so to complete the seven point data average.
