Tertiary students from sub-Saharan Africa are the most mobile in the world, with one out of every 16 – or 5.6 percent - studying abroad, according to a report from the UNESCO Institute for Statistics (UIS). "What this report shows is that the real dynamic in tertiary education is coming from African, Arab and Chinese students. They are the driving force behind the internationalization of higher education," says Hendrik van der Pol, UIS Director.
