Top universities are still the preserve of students from more affluent backgrounds, according to new research.
The study by the Independent Commission on Fees reveals those from the richest neighbourhoods are three times more likely to go to university than those from the poorest areas.
Wealthier students are also 10 times more likely to attend a leading university.
These gaps are slightly narrower than four years ago, but "remain unacceptably large", the report concludes.
The findings are based on analysis of data from Ucas, the university admissions service.
