worldbank.org (2025) The World Bank has worked to strengthen social registries in LAC and globally for several decades. This technical note aims to contribute to reducing the knowledge gap on the state of the art and challenges of social registries in LAC, identify where they are about various analysis criteria, and generate recommendations on strategies to strengthen and consolidate their role in the design, implementation, and evaluation of social policies in the region. This technical note is organized into five sections, including this introduction. The second section presents the role of social registries in social policy. Section three presents the evolution of social registries in LAC and how they adapted to the challenges that arose to provide immediate responses during the COVID-19 pandemic. The fourth part generally describes the state of the art of social registries in the region, analyzed from five pillars: (i) institutional arrangements, (ii) structural aspects, (iii) implementation chain, (iv) information and interoperability systems, and (v) performance measures. The fifth section presents the main challenges facing the registries and the study's recommendations.
