UN Peacekeeper Fatality Rates by Mission, 2010 to Present

Semi-annual fatality rates for uniformed personnel in United Nations Peace Operations from 2010 onward, expressed per 1,000 personnel. The dataset is produced by the United Nations Peace and Security Data Hub, integrating official UN sources for mission fatalities and personnel contributions. Rates are calculated separately for all missions and for active peacekeeping missions only.

Use Cases

• Analyze trends in peacekeeper safety over time based on the semi-annual casualty rate data.
• Compare fatality risk across different UN missions based on the mission-specific rates.
• Model the relationship between personnel contributions and casualty incidents based on the integrated fatality and personnel data.
• Assess the operational tempo or danger level of active missions based on the separate dataset for active peacekeeping missions.

Strengths

• Data spans from 2010 to the present, providing a multi-year time series.
• Rates are calculated per 1,000 personnel, enabling standardized comparison.
• Integrates two official UN sources: Mission Fatalities and Historical Uniformed Personnel Contribution.
• Provides a separate dataset focused specifically on active peacekeeping missions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
