The term global city alludes to authority, complexity, leadership, affluence, influence and global interconnectedness. To be called a global city means that activities and ideas stemming from the city have the ability to shape the world. Although there is no tangible method to assign this label to any one city, it is undoubtable that centers such as New York and London can lay claim. Assessed as individual metropolises, these two cities have a strong international image that incorporates diverse cultural events, lively populations and commanding business and financial clout. It is thus possible to make a number of broad observations about the nature of global cities.
