According to data from the Organisation for Economic Co-operation and Development (OECD), the mobility of international students has significantly increased in the past four decades, from 250,000 in 1965 to approximately 3.7 million in 2011.[2][3] These statistics show the academic mobility of international students that aim for a degree rather than short-term "study abroad" education.[4] UNESCO suggests that there are over 2.7 million students studying in a country other than their origin country.[5] The group of Asian students is the largest constituent part of all students who enrolled in the overseas schools. They make up 45 percent of total of international students in OECD countries and 52 percent of total in non-OECD countries.[6]
