Roughly 5,550 years ago the first urban cities sprung up in the Sumer Region. From this period, during the First Urban Revolution, it would take some 5,325 years for the world urbanization rate to reach 5%. In 1825, motorized transportation arrived on the scene. Between that date and today, during the Second Urban Revolution, the world urbanization rate rose from 5% to nearly 50%. This growing population polarization is coupled with an even more pronounced polarization of economic power. Current urbanization bears many pitfalls, which vary according to development levels, yet also raises much hope of the emergence of a new urbanity.
