对当前都市圈定义的不满以及在非都市区域内缺乏差异化提供了本文研究的动机。不仅是首都圈，还包括较大的城镇（1万∼49999个）和较小的城市（2500∼9999个），都是以人口普查区而不是郡县作为分配地区的基础。该分析使用了1990年人口普查确定的城市化地区和一地到一地的通勤流量。结果包括人口从大都市向非大都市的适度转移，以及大都市地区面积的显着减少，许多地区的解体，以及频繁的重新配置为更现实的定居形式。
Discontent with the current definition of metropolitan areas and the lack of differentiation within nonmetropolitan territory provided the incentive for the research presented here. Census tracts rather than counties were used as the building blocks for assignment of tracts, not just to metropolitan areas, but also to larger towns (10,000 to 49,999) and to smaller urban places (2,500 to 9,999). The analysis used 1990 census-defined urbanized areas and tract-to-tract commuter flows. Results include a modest shift of population from metropolitan to nonmetropolitan, as well as a significant reduction in the areal size of metropolitan areas, disaggregation of many areas, and frequent reconfiguration to a more realistic settlement form.
