America's future geography, according to Richard Florida:

What will this geography look like? It will likely be sparser in the Midwest and also, ultimately, in those parts of the Southeast that are dependent on manufacturing. Its suburbs will be thinner and its houses, perhaps, smaller. Some of its southwestern cities will grow less quickly. Its great mega-regions will rise farther upward and extend farther outward. It will feature a lower rate of homeownership, and a more mobile population of renters. In short, it will be a more concentrated geography, one that allows more people to mix more freely and interact more efficiently in a discrete number of dense, innovative mega-regions and creative cities. Serendipitously, it will be a landscape suited to a world in which petroleum is no longer cheap by any measure. But most of all, it will be a landscape that can accommodate and accelerate invention, innovation, and creation—the activities in which the U.S. still holds a big competitive advantage.
