How significant can the Age of a Voter be in terms of Voting Behaviour [1983, 2017]

-Age has never been as Significant as Today -1983 saw 42% of 18-24 for Cons and 38% for Labour. This has changed Drastically. -2017 saw Labour get Majority from 18-39 Yr olds -YouGov stated that every 10 Years Older a person was in 2019, they would be Less Likely to vote by Labour [decreased by 8 Points] while more likely to favour Cons -Gap between the Youth and Old is Greater than the Gap of AB and DE Voters. Age therefore more Significant -Age only has been Important for the last 2 Elections, so the next Election will determine if it remains Important
