Research Note: Africa by numbers: Reviewing the database approach to studying African economies
这篇研究笔记指出，基于数字研究非洲经济增长和贫困可能具有误导性，因为数据质量差、不完整且分布不均，为研究者提供了如何正确使用数据的指导。
We know less about growth and poverty based on numbers in African economies than we would like to think. Numbers are soft, and data availability is sparse, sporadic, and uneven. For researchers and data users, whether engaged in inferential or descriptive statistics, the message is that studying Africa by numbers can be misleading. This research note surveys the knowledge gap and provides guidance on how to and how not to study Africa by numbers.
