That chart is very interesting to see. I wonder though if it quite answers the question about to what extent there was a beneficial effect from grammar and direct grant schools in increasing Oxbridge admissions from those sectors (in proportion to private) ,in the 20th century? Because during that period only about 5% went to university at all rather than straight into work or an apprenticeship. Also fewer girls by far went to Oxbridge until relatively recently.
I am no good at understanding statistics but wouldn’t that line simply have gone up because of the higher number over all of university applicants these days?
Would you expect a higher number of grammar schools to increase the proportion of Oxbridge places going to state school pupils? There are definitely some clear reasons why it might do, since at least some of the kids who'd have gone grammar back in the day would, after the demise of grammars, end up going private instead. Heck, in a few cases, some entire grammar
schools, such as the one that Keir Starmer attended, went private in 1970s. So of course you'd expect the grammars being [largely] abolished to reduce the number of state Oxbridge places.
There might also be an effect, largely unprovable, whereby grammar schools were providing a better education to kids who wouldn't ever have been able to afford private than the comps would go on to do.
Set against this second point is the fact that the 11+ was a test for, let's face it, 10 yr old kids [and as such a fairly seriously flawed predictor of performance at 18, especially with variable levels of preparation for the test], and notorious for favouring middle class children [hence its demise, even in those 1970s days of limited transparency and relative respect for one's betters, etc]. Secondary moderns were abysmally resourced comparde to comprehensives and used to send no kids, ever, to Oxbridge, whereas comprehensives now account for c40% of the total, i.e. pretty much exactly as the same as grammars at the late 60s zenith of their powers, with the few surviving grammars still contributing about c20%.
So does the data show the demise of grammars, which started in the late 60s and was largely finished by about 1980, reduce the number of state school? e.g. if you squint really hard at the shape of the line between the late 60s and early 80s? It doesn't obviously look like it?
