Describe how the population movements from the Northeast to the Sunbelt, and from inner cities to the suburbs, altered major features of American society as well as its center of gravity. Which of these two migrations do you regard as the more significant, and why

The movement from the Northeast to the Sunbelt occurred after the extensive use of air conditioning made the hot weather of the South more bearable for a larger number of people. Many people moved to the Sunbelt in order to enjoy better weather and recreational opportunities.

On the other hand, the movement from inner cities to the suburbs occurred when the economy of the United States improved and new families wanted their own homes that were suitable for nuclear families. The suburbs also benefitted from a better road system and the availability of cars.

I believe that the latter movement was the most significant one, as it left a deep mark on the lifestyle of the United States. It led to the development of extremely large supermarkets. It also made owning a vehicle vital. Finally, this change also led to the rise of a "commuter culture" and to the disappearance of housing in the center of major cities.
