Well, well. Look at what’s emerged from a Freedom of Information trawl.

A bleak portrait of racial and social exclusion at Oxford and Cambridge has been shown in official data which shows that more than 20 Oxbridge colleges made no offers to black candidates for undergraduate courses last year and one Oxford college has not admitted a single black student in five years.

The university’s admissions data confirms that only one black Briton of Caribbean descent was accepted for undergraduate study at Oxford last year.

Figures revealed in requests made under the Freedom of Information (FoI) Act by the Labour MP David Lammy also show that Oxford’s social profile is 89% upper- and middle-class, while 87.6% of the Cambridge student body is drawn from the top three socioeconomic groups. The average for British universities is 64.5%, according to the admissions body Ucas.

The FoI data also shows that of more than 1,500 academic and lab staff at Cambridge, none are black. Thirty-four are of British Asian origin.

One Oxford college, Merton [Motto: “At the cutting edge of teaching and research for over 700 years”], has admitted no black students in five years – and just three in the last decade. Eleven Oxford colleges and 10 Cambridge colleges made no offers to black students for the academic year beginning autumn 2009.

Oxford’s breakdown of its latest undergraduate admissions figures, published on its website, shows that just one black Caribbean student was accepted in 2009, out of 35 applications.
