Ethnicity has played a core role in the construction of African security institutions, with leaders often relying on coethnics to secure military loyalty. Such practices, termed ethnic stacking, likely have profound consequences for a range of important outcomes, from combat effectiveness to coup propensity to democratization. The Ethnic Stacking in Africa Dataset provides the first comprehensive data on the ethnic stacking practices of all African countries, from independence to 2018 (with 95.7% of leaders and 98.3% of country years recovered). This new data will allow scholars to better understand African militaries and their behavior and capabilities.

非洲数据集中的民族堆叠：当领导人使用归属身份来建立军事忠诚度时

种族在非洲安全机构的建设中发挥了核心作用，领导人往往依靠种族来确保军事忠诚。这种被称为种族叠加的做法可能会对一系列重要结果产生深远的影响，从战斗力到政变倾向再到民主化。非洲民族叠加数据集提供了从独立到 2018 年所有非洲国家民族叠加实践的第一个综合数据（95.7% 的领导人和 98.3% 的国家年恢复）。这些新数据将使学者能够更好地了解非洲军队及其行为和能力。
