Multiple sources have found a correlation between having a higher level of education and voting 'remain', as well as a correlation between having lower educational level and voting 'leave'. YouGov found that, among those who voted in the referendum, 68% of voters with a university degree voted 'remain', whereas 70% of voters educated only to GCSE level or lower voted 'leave'. Similarly, Curtice reports that "university graduates voted by around three to one in favour of Remain, whereas nearly four in five of those without any educational qualifications voted to Leave".
