iadb.org (August 2025) The System for the Identification of Potential Beneficiaries of Social Programs (Sisbén) is Colombias main instrument for targeting social policies. To date, Sisbén has gone through four versions and uses statistical tools and techniques to identify and rank the population according to their socioeconomic situation. Recently, Colombia began the transition from Sisbén to the Social Registry of Households (Registro Social de Hogares, RSH). This transition entails moving from a tool based on socioeconomic surveys to a system that seeks to capture the socioeconomic situation of the entire population through interoperability with administrative records (CONPES 2016) and to integrate an analysis of the social service supply (Decree 812 of 2020, Article 2). From its beginnings in 1994 to the present, Sisbén has progressively strengthened its methodology, operations, and technology, enabling the transition to a more ambitious instrument such as the RSH.
