The Community-Based Monitoring System (CBMS) is an organized technology-based system of collecting, processing, and validating local-level data based on a census of households in the locality. It was institutionalized by virtue of Republic Act 11315 in April 2019. This paper aims to illustrate how local government units (LGUs) can use the CBMS in their planning process. The study finds that since the CBMS provides disaggregated local-level data, local planners can use it to identify and target vulnerable members of society better. Regular updating of the CBMS would also allow LGUs to generate panel data, which could help monitor the long-term impact of policies and programs on vulnerable households. Moreover, geotagging of households through the CBMS allows local officials to locate those at risk from natural hazards.
