Assessing the Use of Call Detail Records (CDR) for Monitoring Mobility and Displacement

This report, jointly produced by Princeton University and the International Organization for Migration (IOM), provides an overview of the opportunities, limitations, and risks of using call detail record (CDR) data for monitoring human mobility and displacement. CDR presents a potentially valuable opportunity for humanitarian actors and stakeholders interested in the pursuit of mobility and displacement monitoring to expand upon their existing methods. 

This report sought to address the question: to what extent is CDR use ethically permissible and practically feasible in shaping humanitarian response in diverse displacement contexts, by enabling better analysis of mobility?
