Some people don’t seem to get this. It isn’t about individual streets or houses. It’s about approx 1500 people, using data from census forms, grouped together in a conveniently compact locality. What is does show is that some people who think they live in a moderately well-off area are actually surrounded by people who are in some ways (health, education, income etc) deprived. When you start to link indices of deprivation with degrees of being ‘posh’, that’s just ignorance and snobbery.
