My husband just shuffled in and poured cold water all over me, said there are something like 3M newly registered voters, and most of them are under 35.... that's a bit of a wild card.
BBC Scotland did a bit of analysis on this. Newly registered voters are always skewed towards under 35s because they include 1st time voters. However it is also true to say that a proportion of newly registered voters are routinely duplicate applicants or not actually eligible to vote.
"During the 50 days before voter registration deadline day, more than a third of applications, 1.3 million, were from under-25s. And while that is a significant increase on the 2017 figure of nearly 900,000, it should be seen in the context of an overall boost to the numbers of people applying to register. As a proportion of overall applications it is almost exactly the same as in 2017.
However, there has been a fall in the proportion of applications coming from 25-34 year olds, a group that was seen by experts as key to Labour's result two years ago. In 2017 33% of applications were from this group, this year it's below 30%.
Conversely, there's been an increase in the proportion of applications by voters over the age of 45, who make up nearly 20 percent of the total this year, compared with 16.5% in 2017.
So - while nearly half a million young people applying to join the electoral register might initially look like good news for Labour, the detail suggests the figures might not be quite as helpful for them as they first appear."
