This indicator is providing a picture of student mobility and the extent of the internationalisation of tertiary education in OECD countries and partner economies. It shows global trends and highlights the major destinations of international students and trends in market shares of the international student pool. Some of the factors underlying students’ choice of a country of study are also examined. In addition, the indicator looks at the extent of student mobility in different destinations and presents the profile of the international student intake in terms of their distribution by countries and regions of origin, types of programmes, and fields of education. The distribution of students enrolled outside of their country of citizenship by destination is also examined. Finally, the contribution of international students to the graduate output is examined alongside immigration implications for their host countries. The proportion of international students in tertiary enrolments provides a good indication of the magnitude of student mobility in different countries.
