In 2010, the Swedish nonprofit Flowminder analyzed the movements of two million mobile phones in Haiti to track population movements following the earthquake there. The effort, intended to support humanitarian work, was made possible through a collaboration with the mobile provider Digicel Haiti and other organizations who provided anonymized data on the position of 1.9 million SIMs in Haiti from 42 days before the 2010 earthquake to 158 days afterwards. Through this collaboration with Digicel Haiti, Flowminder could estimate real mobility of the population after the earthquake. This data supported research and provided critical support to the United Nations and other relief agencies by helping them predict post-earthquake population displacement patterns.
