worldbank.org (01.03.2025) This policy note consolidates the highlights of a study funded by the Sahel Adaptive Social Protection Program (SASPP), exploring the role and operationalization of dynamic social registries in low-income and shock-prone contexts, including in the Sahel. The study is based on innovations in dynamic social registries in low- and middle-income countries, identifying what works and key considerations in the design and adaptation of social registries toward their dynamic updatability and scalability in contexts marked by high exposure and vulnerability to shocks, high levels of poverty, and/or low levels of digital penetration.
