Although sprawl is a growing national debate, there have been few efforts to measure or monitor changes in degree of sprawl over time. By using a methodology that employs census data, this sprawl index allows computation of levels of sprawl and examination of temporal and geographic changes. The results show that sprawl has increased over the past decade in many metropolitan areas. There are important geographic variations in sprawl, implying that it is neither inevitable nor universal.
尽管城市扩张是一个日益引起全国性争论的话题,但几乎没有人努力去衡量或监测随时间推移城市扩张程度的变化。通过使用一种采用人口普查数据的方法,这个城市扩张指数能够计算城市扩张水平,并考察其时间和地理变化。结果表明,在过去十年中,许多大都市区的城市扩张有所增加。城市扩张存在重要的地理差异,这意味着它既不是不可避免的,也不是普遍存在的。
