The Constitutional Asylum (COAS) Dataset

The Constitutional Asylum (COAS) dataset provides global panel data on the adoption and substance of asylum provisions in national constitutions across all 193 UN member states from 1789 to 2023. The dataset offers systematic and detailed information on the main characteristics, the legal nature, the types of provisions, and the grounds for protection. It supports both qualitative and quantitative research on historical and cross-national variation in the legal codification of refugee protection.
