Such cities are characterized by their ethnic clustering, network of international connectivity, and convergence of technological innovation. Global cities, such as San Francisco, are considered to be complex and require a high level of talent as well as large masses of low wage workers. A divide is created within the city of ethnic, typically lower-class neighborhoods, and expensive ones with newly developed buildings. This in turn creates a population of highly educated, white-collar individuals as well as blue-collar workers, many of whom are immigrants, and who both are drawn to the increasing number of opportunities available.Competition for these opportunities pushes growth and adaptation in world centers.
