You can see this just by thinking intelligently for a minute looking at the age and ethnicity profile, like, hmm, I wonder where these 60s or older ethnic minorities came from and under what terms (answer: their free movement through the British empire!)
Nor were they anymore likely to be given social housing at the time" for a variety of reasons (some, simply that British internal migrants faced much more racism then than now, some, an ideological opposition to using right to buy) the white British were more likely to buy their flats.
Wouldn't that mean that if you're 60 to 70 years old today you had to come as a small child with your parents for this to be an explanation? And the proportion of social tenants in that age bracket is still only marginally higher?
The TLDR of all this, I believe, is that the Tories have not yet learned they've moved too far right for the British electorate, and save Labour messing up completely, a vote for Jenrick is a vote for a longer period of navel-gazing.
