This article introduces the Deadly Electoral Conflict dataset (DECO): a global, georeferenced event dataset on electoral violence with lethal outcomes from 1989 to 2017. DECO allows for empirical evaluation of theories relating to the timing, location, and dynamics of deadly electoral violence. By clearly distinguishing electoral violence from related (and sometimes concurrent) instances of organized violence, DECO is particularly suitable for investigating how election-related violence is connected to other forms of violent political contention. In the article, we present the theoretical and methodological underpinnings of the data collection and discuss empirical patterns that emerge in DECO. We also demonstrate one potential use of DECO by examining the association between United Nations peacekeeping forces and the prevalence of deadly electoral violence in conflict-affected countries.

本文介绍了致命选举冲突数据集 (DECO)：一个关于 1989 年至 2017 年具有致命结果的选举暴力的全球地理参考事件数据集。 DECO 允许对与致命选举暴力的时间、地点和动态相关的理论进行实证评估。通过明确区分选举暴力与有组织暴力的相关（有时是并发）实例，DECO 特别适合调查与选举相关的暴力如何与其他形式的暴力政治争论相关联。在文章中，我们介绍了数据收集的理论和方法基础，并讨论了 DECO 中出现的经验模式。
