There is no way that poverty can be fully tackled without policies designed to address the multiple disadvantages faced by people due to the combination of ascribed attributes including gender, age, race, ethnicity, disability, migration status, and sexual orientation and gender identity (SOGI). And it is central to the Sustainable Development Goals’ (SDGs) overarching objective of inclusive development or ‘leaving no one behind.’ This means that intersectionality must be captured in data and embedded in evidence-based policies. But this is far from easy because, at present, the data is still limited. The Center for Global Development, Data2X and Open Data Watch have partnered to help improve the availability and use of this data.
