In partnership with the United Nations Population Fund (UNFPA) Maldives and working closely with the National Bureau of Statistics of Maldives, this project sought to leverage Big Data sources, such as the mobile phone records (CDRs) and official statistics (household surveys) to provide data and study the effects of COVID-19 mobility restrictions on the population dynamics and mobility in the country. The study also analyzed the intricate relationships between attitudes, actual behavior and socioeconomic background in the Maldives by combining NBS survey data with movement patterns in a privacy-preserving manner. One of the main objectives of the project was to set a new benchmark for innovative application of mobile phone analytics in the region and beyond as a way to address population needs and monitor the impacts of shocks and stressors. The outputs of this projects included an analysis and policy paper with recommendations synthesizing key insights on the population dynamics obtained through CDR analysis and outlining applications towards advancement of 5 SDGs; and a capacity building toolkit and ‘how-to” guide for using innovative data analytics methodologies, collection and analysis of alternative sources of data.
