"More than half the world's population lives in cities; by 2050, it will be more than 75%. Cities are often the economic, cultural, and political drivers of states, and of globalization more generally. Yet, constitutionally-speaking, there has been little to no consideration of cities (and especially megacities, with populations exceeding those of many of the world's countries) as discrete or distinct constitutional or federal entities, with political identities and economic needs that often differ from rural regions or so-called "hinterlands."
