It also revealed that the country's higher education is of significant economic value as U.K. higher education exports netted around £10 ($17 billion) billion in 2011-12.
Undergraduate courses saw a fall of almost a quarter in international students from the European Union. Rising tuition fees -- the maximum level charged by universities rose from £3,465 to £9000 in September 2012 -- made courses offered by the U.K. universities' European counterparts a cheaper alternative.
The number of students from Pakistan and India fell by 11 percent and 13 percent from 2011-12 to 2012-13 respectively.

International entrants onto postgraduate courses fell to 144,760 in 2012-13 from 150,425 in 2011-12.

The dip was partly offset by the number of international students from China and Malaysia which rose 9 percent and 14 percent from 2011-12 and 2012-13 respectively.
