Models of epidemic disease and programs for their management require accurate population data as a critical component of most studies. But the traditional definitions of urban places assumed discrete borders and localized populations. The vast increase in urban travel at all scales has raised the problem of how we define those urban populations. This paper reviews the issues as an areal unit problem within the context of the evolving idea of "megaregions" and their defintion.
疾病模型和管理计划都需要准确的人口数据，这是大多数研究的关键组成部分。但是，传统的城市地点定义假设了离散的边界和本地化的人口。城市交通在各个层面上的大规模增长，引发了如何定义这些城市人口的问题。本文回顾了作为一个区域单位问题，探讨了“大都市地区”及其定义的不断发展的概念。
