UN Peacekeeper Fatality Rates in Active Missions, 2010-Present

Uniformed personnel fatality rates in active United Nations peacekeeping operations from 2010 to present, calculated semi-annually. Rates are expressed per 1,000 personnel and derived from official UN casualty and personnel contribution data. The dataset is maintained by the United Nations Peace and Security Data Hub and was last updated in March 2026.

Use Cases

• Analyzing trends in peacekeeper safety over time based on semi-annual fatality rates.
• Comparing risk levels across different active peacekeeping missions.
• Modeling the relationship between mission duration and casualty rates.
• Assessing the impact of operational changes on personnel fatalities.

Strengths

• Data integrates two official UN sources: Mission Fatalities and Historical Uniformed Personnel Contribution.
• Covers a time range from 2010 to the present, updated semi-annually.
• Rates are calculated per 1,000 personnel, enabling standardized comparison.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is limited to currently active missions; historical rates for concluded missions are not included.
