This article introduces the Issue Correlates of War Identity Claims Dataset. An identity claim occurs when two states diplomatically contest the treatment of an ethnic group that both states share. A state that advances such a claim (i.e. the challenger) demands that the other state (i.e. the target) either: (i) change its domestic treatment of the group, (ii) grant the group independence, or (iii) allow the group to reunite with the challenger state (i.e. irredentism). Our research locates all known instances of identity claims throughout the world from 1946 to 2021 ( n = 111; 45 ongoing as of 31 December 2021). We first highlight the differences between these data and what appears in various existing datasets. We then elaborate on our data generating and coding processes, before descriptively presenting some of the dataset’s noteworthy characteristics (e.g. frequency over time and across regions; the most common challengers, targets, and ethnic groups involved; and claim militarization rates). Finally, we conclude with a discussion about promising ways to use the data in future research.

1946-2021 年战争相关 （ICOW） 身份索赔数据集


本文介绍了战争身份索赔数据集的问题相关性。当两个国家在外交上对两国共有的种族群体的待遇提出异议时，就会发生身份声明。提出这种主张的国家（即挑战者）要求另一国（即目标国家）：（i） 改变其对该群体的国内待遇，（ii） 授予该群体独立性，或 （iii） 允许该群体与挑战者国家重新统一（即不屈不挠）。我们的研究找到了 1946 年至 2021 年全球所有已知的身份声明实例（n = 111;截至 2021 年 12 月 31 日，有 45 个正在进行中）。我们首先强调这些数据与各种现有数据集中出现的数据之间的差异。然后，我们详细说明了我们的数据生成和编码过程，然后描述性地展示了数据集的一些值得注意的特征（例如，随时间和地区变化的频率;涉及的最常见的挑战者、目标和种族群体;以及声称军事化率）。最后，我们讨论了在未来研究中使用数据的有前途的方法。
