Introducing the Deadly Electoral Conflict Dataset (DECO)

Abstract

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.
