This project, supported by UNFPA Maldives and the National Bureau of Statistics, aimed to use Big Data to shed light on demographic features that have a wide range of implications for development policies and programs. Specifically, our partners at Fundazione Bruno Kessler (FBK) developed a prototype  to analyze population density and movement patterns that leveraged call detail records (CDRs) and new data analytic techniques by utilizing the temporal dynamics derived from mobile data, while preserving the anonymity of mobile users.
