Between 2003 and 2012, UK student enrolment in the biological and physical sciences rose by more than 30% and overall university enrolment rose by more than 6%, according to a report by the country's Higher Education Statistics Agency. But across all fields, the number of postgraduate researchers increased by only 0.1% for 2012–13, the smallest increase since 2004. In the decade since 2003, enrolment at UK institutions fell sharply for students from the Middle East (−124%), Asia (−63%), Africa (−36%) and North America (−31%), but rose for students from Australasia (22%) and South America (21%).
