Jackson, from his magnificent piece on suburbanization Crabgrass Frontier. Suburbanization has been probably the most significant factor of change in U.S. cities over the last 50 years, and began 150 years ago.

The first on is that Americans have such low density residential areas, and often their is not a distinction between urban and rural. Our cities were laid out over space, with even New York City and Philadelphia not as densely populated as some cities in Europe. The next distinguishing factor is a want to own a home.
