China adds “Super-large sized cities” to urban classification system
The official Chinese city classification system, which categorizes cities on the basis of their population, has until now been composed of four tiers. A fifth tier has been added, with the new “super-large sized cities” regrouping metropolises with more than 10 million inhabitants. It was added on top of the former largest tier that included cities of more than 5 million.
By isolating the largest urban areas from the rest, authorities now hold the power to limit migrations towards these over-populated urban centers while going forth with the liberalization of the hukou system in smaller cities, whose aim is to sustain their economic growth by supporting urbanization.
