From political violence to attacks on press freedom, the factors that weaken elections are measurable. That’s why the Kofi Annan Foundation and UpSight created the Electoral Vulnerability Index—a data-driven tool updated annually to help governments, civil society, and citizens understand which elections might be affected by violence. An Overview of the Latest IndexElectoral Vulnerability Index 1: Overall Vulnerability to ViolenceIndex 1 uses a weighted ensemble of models to identify the overall vulnerability to violence. Find out more about the ensemble model in the 2025 EVI Technical Report or the working paper introducing the forecasting system. The Maps below reflect the Index findings, showing the risk of violence and probability of violence in countries holding elections over the next 18 months.
