The Issue Correlates of War (ICOW) Project collects data on territorial claims between sovereign nation-states since 1816. It is compiled into three related data files covering claim identification, annual dyadic details, and settlement attempts. The project is authored by Paul R. Hensel.
Use Cases
- Modeling the duration of territorial claims based on claim-level start and end dates.
- Analyzing dyadic conflict characteristics based on annual claim-dyad-year data.
- Evaluating the effectiveness of third-party settlement attempts like mediation or arbitration.
- Studying the termination patterns of territorial disputes based on the form of claim termination.
Strengths
- Data collection covers all world regions since 1816, providing a long historical scope.
- Structured into three interlinked files for claim-level, dyad-year, and settlement attempt analysis.
- Includes specific details on settlement methods such as good offices, mediation, and adjudication.
Limitations
- Row count and file size are unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Last update date is unknown; freshness unverified.
