World's Largest Cities
Global urbanization and the emergence of large cities has been a
significant process with far reaching economic and social impacts:
- Urbanization involves a much higher level of concentration
of the global population, that used to be more dispersed. Higher
levels of concentration are easier to service from a market
perspective, but are also prone to congestion and diseconomies.
- Several mega-cities of more than 8 million have emerged.
These cities command a large share of the global wealth creation
and dominate their respective national economies.
- Urban residents have different activities, lifestyles and
levels of consumption than rural residents, particularly in
developing countries.
