This policy brief documents the key insights and learnings from the development of the Cambodia Vulnerability Mapping tool. This tool combines traditional and big data sources to provide a multidimensional perspective on vulnerabilities in Cambodia. By integrating different datasets, policymakers can identify patterns and interactions of overlapping deprivations that are often overlooked when studying vulnerability separately. The tool allows users to explore vulnerabilities alongside specific indicators such as education, health, and living standards at various geographic levels.
