Data-Pop Alliance is a global coalition on Big Data and development created by the Harvard Humanitarian Initiative (HHI), MIT Media Lab, and Overseas Development Institute (ODI) that brings together researchers, experts, practitioners, and activists to promote a people-centered Big Data revolution through collaborative research, capacity building, and community engagement. Flowminder Foundation is a non-profit organization registered in Sweden, founded by academic researchers who pioneered the application of using anonymised mobile network data for public health applications, such as infectious disease in 2008 (malaria, cholera, dengue) and disaster response (Haiti 2010, Nepal 2015). Flowminder is closely integrated with WorldPop, a leading open data repository for geospatial demographic data used by major development agencies and governments worldwide. “Flowminder has an unparalleled track record of innovation and application of new digital data sources to support development and humanitarian organizations in the field. We are thrilled to welcome them as a core member alongside HHI, MIT Media Lab and ODI as we proceed to promote a people-centered Data Revolution,” says Emmanuel Letouzé, Director of Data-Pop Alliance. “With Flowminder as a core member we hope to continue fostering collaborative and connected approaches missing in the space.” “Data-Pop Alliance has in a short time become the leading global initiative and think-tank on Big Data and development issues. As we have a shared vision and complementary focus areas we are excited to join forces and together be more active in contributing to the policy dialogue, as well as designing and implementing joint initiatives in support of the Sustainable Development Goals,” says Linus Bengtsson, Executive Director of Flowminder Foundation.
