The project “Immigration Enforcement Across the World: Drivers and Consequences of Deportation Risk (DEPRISK)” created a country-by-country database on annual deportation corridors by collecting administrative data from governmental sources in the deporting countries, both through publicly available statistics and via official requests for access to information. The database currently includes bilateral data from 42 deporting countries, including most OECD countries, spanning the period from 2000 to 2023, encompassing 7,200 deportation corridors. This methodological note describes the variables of the DEPRISK database and the challenges that arose from joining data across countries with different legal terms, procedures, and reporting systems. The country annexe presents the country-specific legal terms and data sources, and justifies all steps and decisions taken in creating variables.
