Data provide critical inputs in designing effective development policy recommendations, supporting their implementation, and evaluating results. In this new report “Big Data in Action for Development,” the World Bank Group collaborated with Second Muse, a global innovation agency, to explore big data’s transformative potential for socioeconomic development. The report develops a conceptual framework to work with big data in the development sector and presents a variety of case studies that lay out big data’s innovations, challenges, and opportunities. Of note are brief mentions of InaSAFE, developed under the Open Data for Resilience Initiative.
