Not all countries or territories report the number of internationally mobile students that they host, and thus the
number of inbound mobile students in a given region may be underestimated.
u

of outbound students from a given country. Not all host countries specify the country of origin of the
internationally mobile students that they host, and thus the number of outbound students from a given
country may be underestimated.
v
