Abstract

Call Detail Records have great potential to drive humanitarian action for early warning, monitoring, decision-making, and evaluation. The Data For Development Challenge leveraged mobile phone data for Development in Senegal. We further explored methodologies and protocols to use this data to support humanitarian action for refugees. Obtaining estimates of forcibly displaced population requires not only data analysis but also a solid protocol to ensure privacy and the right outcomes of the project. When no refugee labeled data is available, a framework to identify displaced population is necessary. We present a methodology to analyze mobility that minimizes privacy risks by subtracting mobility patterns of the population until finding those patterns indicative of the displaced population.
