Traditionally, Europe, Africa and Asia are considered to be the "Old World" and the Americas, North and South are considered "New World" (sometimes Australia and New Zealand are included as well).
However, Europe aside, if you look at most of the other parts of the Old World, it actually appears to be the case that their really big cities are newer due to later industrialization and urbanization, even if their history of civilization is old. Abu Dhabi or Shenzhen, and many other Asian or Middle Eastern cities are much newer than Chicago, New York, Buenos Aires, and other large US, Latin American cities and even Australian or Canadian cities. And, as Africa too urbanizes, people there are also coming to live in very new, rapidly growing cities.
Since most of the developing world is still in the Old World and is catching up on urbanization, is it likely that the average citizen in the Old World currently lives in a city or town, or at least a part thereof where the housing stock, infrastructure etc. is "newer" than the average citizen of the New World?
If so, for how long has this been the case or will be the case I wonder.
