This is no surprise whatsoever. If you live in a poor area, you go to a poor school (which makes the arguments about Academies bringing in a socially divisive education system seem a bit odd considering that's exactly what we have already). Cambridge University took more State school pupils in 1970 than it does now (because of Grammar schools).
Poor schools do not attract many academic teachers. Funnily enough, they go to the schools where they can actually teach their subject rather than spend the day giving out coloured pencils and trying to prevent a riot.
What poor schools do sometimes manage is to encourage their best pupils to apply to study some Mickey Mouse course at an institution whose name no employer can read without collapsing into a fit of giggles. Three years later they have a colossal debt and a worthless certificate.
It could hardly be more obvious that unless schools can select by academic achievement, then the Office for Fair Access will be copying and pasting the same report in another 10 years time.
