India has achieved this feat in just two cities and that too with some help from the redrawing of maps. The positive externalities in this case are termed agglomeration economies; this has driven urban growth for centuries, if not millennia. This is not an argument for government intervention to limit megacity sizes but merely one for creating new but big enough cities or turning smaller cities into bigger ones. India needs a lot of new, big cities which provide good infrastructure to attract firms and also preserve a space for social interaction among all strata of society. Does India need a large number of million-plus cities in addition to its handful of multimillion metropolises?
