 @43d7c4ea I'm surprised - and dismayed - to see that 'immigration' line as it is for the sub-50 year old groups. Rather than earlier, discrete societal/education regimes yielding less 'liberal' views, it seems to be more linked to just plain ageing. Which would also tend to suggest the Tories will continue to be fed with a nice stream of ageing xenophobes for a long time yet.

I wonder if it's an age effect or a cohort effect?

An age effect is one where people experience something at a particular time in their lives. For example, menopause is an age effect.

A cohort effect is one where people born at a particular time have experienced something that others haven't. For example, having been exposed to leaded petrol fumes during your childhood is a cohort effect.

The US Republican party is a good example of a cohort effect: between 1996 and 2016, the average age of a Republican voter increased by 18 years. That means it's not "old people vote Republican" but "people born before 1970 vote Republican", which has radically different implications for the future. I have not seen a similar set of statistics for the UK but would be really interested if anyone has any.

Yes, so would I.... I imagine John Curtice and/or the UK social attitudes survey people might have something to offer?
