Some realities about sprawl and urban decline

Many urban analysts believe suburban sprawl has become an important issue because it helps generate two types of problems: growth-related difficulties like rising traffic congestion, and high concentrations of poor minority households in core-area neighborhoods. However, a careful regression analysis of measures of both sprawl and urban decline shows no statistically significant relation between these two conditions. The basic nature of the American urban development process would cause core-area poverty concentrations even if sprawl were replaced by more compact growth forms. But sprawl does aggravate growth-related problems. Those problems could be attacked through either alternative overall growth strategies-such as high-density, tightly bounded growth-or specific anti-sprawl tactics, such as regional tax-base sharing and regional coordination of land uses. But no feasible policies are likely either to alleviate traffic congestion much or cause most American regions to abandon sprawl.
