Large numbers of people are currently migrating from the poor, inland areas of West Coast Africa to the major cities of Lagos, Accra, Abidjan, and other budding metropolises (Figures 1 and 2). The infrastructure of the Sub-Saharan African cities is inadequate to service their burgeoning populations. An argument is presented for using scientifically derived neighborhoods as the building blocks for current African urban understanding and planning. In this paper, I will explore the neighborhood concept and use available data and new heterogeneity statistics to derive homogeneous neighborhoods. The statistics are explained and maps of Accra neighborhoods are given.
目前，大量人口正从西非内陆贫困地区迁移至拉各斯、阿克拉、阿比让等主要城市以及其他新兴大都市（图1和图2）。撒哈拉以南非洲城市的基础设施不足以满足其迅速增长的人口需求。本文提出将科学划分的社区作为当前非洲城市理解与规划的基本单元。在本文中，我将探讨社区概念，并利用现有数据和新的异质性统计方法来划分同质化社区。文中对这些统计方法进行了解释，并给出了阿克拉社区的地图。
