Million
Five Most Sprawl -  Threatened Small Cities with a population: 200,000 -
500,00

How were the cities ranked?

 Cities were ranked by a committee of Sierra Club suburban-sprawl experts.
 Selection criteria included trends in population and land-area growth for the
 urbanized areas, as well as traffic congestion and open-space loss
indicators.
 Sources include the U.S. Census Bureau, the Federal Highway Administration,
 the Texas Transportation Institute and the American Farmland Trust. Other
 criteria, such as loss of important habitat and historical importance,
were also
 taken into account. The committee ranked cities in three individual size
 categories: major metropolitan areas with populations over one million,
 metropolitan areas with populations between 500,000 and one million, and
 metropolitan areas with populations from 200,000 to 500,000. The urban-area
 populations were determined by 1990 Urbanized Area data compiled by U.S.
 Census Bureau.

 This report ranks cities using criteria weighted to measure recent change in
 urban core population compared to surrounding suburban population. Some
 sprawling cities, especially in the West, don't show up in the rankings
because
 there is little contrast between the old urban core and newer suburban
sprawl.

 These cities - like Spokane, Wash.; Boise, Idaho; and many California
cities -
 developed in the era of sprawl, and never grew densely populated urban cores.
 They grew up sprawled.
