In December 2018 I blogged a demographic analysis of the 2016 referendum result. The conclusion was that the deaths of older, predominantly Brexit-supporting voters leaving the electoral register, and predominantly Remain-supporting young people passing their 18th birthdays meant that the majority for leaving the EU would be gone by the end of 2019.
The age time bomb around Brexit
In the referendum the highest level of support for remaining in the EU was among young voters. Ignoring them sets the UK up for serious difficulties in the future.
