ABSTRACT

In this study, we evaluate how both the definition of middle class and the dataset considered affect the estimated size of the middle class in sub-Saharan Africa. By considering the feasibility of a single definition of a middle class for all African countries based on the World Bank’s PovcalNet database, we estimate the size of this segment for a selection of countries. As part of the regional analysis, we follow with a country and city case study for Kenya and Nairobi. In the case study, to show the complexity and dynamics involved in the measurement at a more disaggregated level, we add the dynamic of currency unit conversion. This statistical assessment, as an investigation into the accuracy of past and current estimates of the middle class in sub-Saharan Africa, is helpful for both assessing the growth of the middle class on the continent and its potential to attract foreign investment.

摘要

在这项研究中，我们评估了中产阶级的定义和所考虑的数据集如何影响撒哈拉以南非洲中产阶级的估计规模。通过考虑基于世界银行的PovcalNet对所有非洲国家的中产阶级进行单一定义的可行性数据库，我们估计了选定国家/地区的该细分市场的规模。作为区域分析的一部分，我们对肯尼亚和内罗毕进行了国家和城市案例研究。在案例研究中，为了在更分解的层面上显示测量中涉及的复杂性和动态性，我们添加了货币单位转换的动态性。本次统计评估是对过去和现在对撒哈拉以南非洲中产阶级估计准确性的调查，有助于评估非洲大陆中产阶级的增长及其吸引外国投资的潜力。
