An earlier post on the Universities of Southeast Asia here used some 2016 data, but I’ve recently come across some 2017 data here and depicted above that also tells an interesting story, albeit differently.
The brief commentary in the link is well worth reading.
The graph (there) is titled Availability of higher education by income which seems, to me, to be a poor choice of a descriptor at best. As the link states, the relative bubble size represents the proportion of the university-aged population in higher education.
More comments to follow another time.
