In this research note, the authors introduce a new dataset called The Citizenship, Migration and Mobility in a Pandemic, or CMMP, which systematically covers information regarding the border closures and lockdowns of 211 countries and territories in response to the COVID-19 pandemic from March 1 to June 1, 2020. The aim of this database is to easily access information which can be used to evaluate the impact of policy implementations restricting migration and mobility during the COVID-19 pandemic. The CMMP combines two sets of data regarding the closures of borders as well as restrictions to internal mobility. Data has been collected from the International Organization for Migration (IOM), and government and media websites. Information regarding travel restrictions across borders show data on self-isolation, quarantine, screening and testing, medical certificates, visas, and no entry. Information regarding restrictions to internal mobility show data on lockdowns, curfews, and closures of businesses and schools. This data base can be used to assess the effectiveness of the policy responses and to understand, explain, and compare the causes of governments’ choices to implement these policies and is available on Cadmus.
