The Guidance Notes seek to help operationalize, simplify and standardize the collection and reporting of data through the application of common language and methods. They provide information on the key issues to take into account in the collection of health data and the types of data that should be collated, and potential stakeholders to engage with. They adapt and complement the UNDRR/UNISDR Technical guidance for monitoring and reporting on progress in achieving the global targets of the Sendai Framework for Disaster Risk Reduction, which has a multisectoral target audience.
