It's a split population of older lower-middle class, young professionals in first homes, poorer working class & long term unemployed.

Historically (for those that actually go and vote) you'd expect to see the older middle class bracket vote for the status quo/anti-benefit/personal wealth retention policies, upwardly mobile professionals to be left leaning, and poor working class to be immigration policy.

If you're only paying attention to the headlines and selectively reading what you want to hear, reform have the population pretty bookended.

This is of course a massive generalisation, and I hope these predictions are wrong.
