A couple here.Source? I'd be interested to see the stats.

"Demographically, UKIP voters attract men slightly more than women – and the party draws its support disproportionately from older people with fewer qualifications. Whereas 46% of all voters are over 50, and 38% under 40, the figures for UKIP are 71% and 15% respectively. And just 13% of UKIP supporters have university degrees – half the national average (though this partly reflects the age profile: older people generally were less likely to attend university when they were young)."

"Turning to UKIP’s support at the individual level, Table 8 compares the social characteristics of
UKIP voters and others, using data from the YouGov 2010 post-election survey. UKIP voters are
slightly older, more likely to be male, white and drawn from social classes C2, D and E, but less
likely to have a degree, compared with voters for other parties. They are more likely to be in the East
of England, South East and South West than other voters, but less likely to be in Scotland or London.
This fits with research on UKIP’s support at the 2009 European elections.30"
I'm trying to find one which is far more comprehensive I've read before, which was based off the last election (showing huge difference on all kinds of social attitudes by political party on race, sexuality, economics & immigration).
But you can see highlighted - it even mentions expected less support in London.
