Description This post-earthquake geospatial study from Haiti is an example of the practical use of Big Data that can be applicable to rapid policy action in post-disaster areas. This study found that routinely collected data on the movements of all active SIM cards in a disaster-affected nation could, with potentially high validity, be used to provide estimates of the magnitude, distribution, and trends in population displacement. With pre-earthquake census data, the method could also provide estimates on area-specific population sizes, which could lead to important improvements in the allocation of relief supplies and the quality of needs assessment surveys. The method was even seen to be feasible for use for close to real-time monitoring of population movements during an infectious disease outbreak.
