Oxbridge hands 30% of all places to applicants from just 10 wealthy boroughs in the South More students were sent by Surrey than whole of Wales and North East Barnet got 130 offers of Oxbridge places from 408 applications last year That's 15 offers per 1,000 16 to 17 year olds in the north London borough This was compared to Dudley, West Mids, which had two offers per 1,000 Anglesey, Flintshire and Middlesbrough areas had the lowest offer rates Cambridge and Oxford are still dominated by students from the South East, it was revealed today. More students were sent to study at the universities by Surrey than the whole of Wales and North East England combined, laying bare the huge gaps in achievement by pupils across Britain. But 1,187 applications came from Wales and the North East, compared to 868 from Surrey - showing how efforts to recruit Oxbridge students from more diverse geographical areas seem to be struggling. Mapped out: The London authorities of Richmond upon Thames, Kensington and Chelsea, and the City of London had more than 25 offers per 1,000 in 2012. The England and Wales average was three per 1,000 Access: More students were sent to study at Oxford (left) and Cambridge (right) by Surrey than the whole of Wales and North East England, laying bare the huge disparities in achievement by pupils across Britain Almost a third of admissions to Oxbridge last year came from successful applicants in only 10 local authorities in the South's wealthier parts. They won more than 1,500 of the 5,100 places available. Barnet in north London got 130 offers of Oxbridge places from 408 applications last year - which is 15 offers and 46 applications per 1,000 16 to 17 year olds in the borough, reported The Guardian. This was far greater than Dudley, West Midlands, which had just two offers and seven applications per 1,000, according to statistics taken from a Freedom of Information Act request and census data. The London authorities of Richmond upon Thames, Kensington and Chelsea, and the City of London had more than 25 offers per 1,000 in 2012. The England and Wales average was three per 1,000. But some areas were so far below the average that they sent less than one per 1,000 to Oxbridge - with Anglesey, Flintshire and Middlesbrough having the lowest offer rates, reported The Guardian.

At the bottom: Anglesey (left), Flintshire and Middlesbrough (right) had the lowest Oxbridge offer rates last year The Oxbridge universities both said they have had some success in attracting more students from lesser-represented parts of Britain, but that variations in academic results limit what they can do. Barnet Buckinghamshire Cambridgeshire Essex Hampshire Hertfordshire Kent Oxfordshire Richmond upon Thames Surrey A Cambridge University spokesman said in a statement sent to MailOnline: 'Admissions decisions are based on students" ability, commitment and their potential to achieve. The success rate of suitably qualified applicants is broadly the same regardless of where in the UK they are from. A spokesman for Oxford University used the example of 45 students achieving AAA at A-Level in Gateshead last year, compared to 1,021 in Hampshire - reflecting both local population and achievement rates. He told MailOnline: "By far the biggest factor affecting applications measured by local authority is school attainment. Success rates for applicants are broadly similar regardless of geography. Oxford runs over 2,400 outreach events a year in every part of the UK, and applications are rising from many areas in northern England and Wales. Oxford targets 62 per cent of applicants from state schools - with the actual figure 63 per cent last year. Cambridge targets 60 to 62 per cent, and matched this in 2012, reported The Guardian.
