The ICOW Territorial Claims Data SetICOW领土争端数据集

The Issue Correlates of War (ICOW) dataset systematically records interstate contentious‑issue disputes, including territorial, river, and maritime claims. It adopts multiple analytical units: claim‑level, dyadic‑claim‑level, dyad‑year‑level, and settlement‑attempt‑level observations. Covering mainly 1816‑2001, it documents claim origins‑terminations, issue salience (0‑12 index), peaceful/militarized settlement attempts, dispute escalation and outcomes, and follows the Correlates of War (COW) country‑code standard.
