In 2014, 55% of Scottish voters rejected leaving the UK in an independence referendum. However, after the 2016 European Union membership referendum, in which Scotland, as well as Northern Ireland, voted to remain in the EU while England and Wales voted to leave, there is the prospect of a second Scottish independence referendum. With some polls on support for Scottish independence being in the majority in 2020, however, polls have a margin of error and many do not include 16-17-year-olds like in the 2014 referendum.
