The premier data on leader survival focus on the violent, dramatic means by which leaders ‘exit’ office. This information, vital for many research questions, constitutes a valuable public good for the community. Yet, it provides an incomplete picture of the political rise and fall of world leaders. The burgeoning study of leaders using survival analysis requires a fine-grained understanding of not just when, but why and how leaders lose power. We cannot, for example, conclude that a leader’s exit implies a successful application of international pressure if her removal stems from pre-set constitutional laws and the immediate successor has long been considered the heir apparent. The Regular Turnover Details dataset remedies this problem. Two principal variables report information about the manner of each leader’s exit and the relationship between outgoing and incoming leaders, allowing analysts to arbitrate between exits that suggest political failure and those that don’t, identify non-political leaders (such as interim and technocratic executives), and determine whether leaders constitute heirs to power or challengers thereto.

领导者生存的首要数据集中在领导者“退出”办公室的暴力、戏剧性方式上。这些信息对于许多研究问题至关重要，构成了社区的宝贵公共利益。然而，它提供了一幅关于世界领导人政治兴衰的不完整图景。使用生存分析对领导者进行的新兴研究需要对领导者失去权力的时间、原因和方式进行细致的了解。例如，如果一位领导人的免职源于预设的宪法法律，并且其直接继任者长期以来一直被认为是明显的继承人，我们就不能得出结论认为，一位领导人的退出意味着成功地施加了国际压力。定期营业额详细信息数据集解决了这个问题。
