Methodology
The following methodology page provides technical understanding of the main concepts of the Risk and Resilience Metrics and, including their source, country coverage, methodological status and publication status. Some metrics are already available and are used in the current country profiles. Other metrics are under development, pending further methodological work, data availability or delivery by external providers.
For the Risk and Resilience Country Profiles, not only information coming from the Risk and Resilience Metrics is presented (which are listed in the methodology table below), but also additional disaster risk metrics, such as Average Annual Loss (AAL), Probable Maximum Loss (PML) and Loss Exceedance Curves (LEC) are shown and provide core evidence on expected and extreme-event losses, as well as Contextual socio-economic, fiscal and financing indicators, such as GDP, poverty, population, public debt, ODA and disaster-risk financing information, which support interpretation and country-level application. For additional sources and methodological notes are provided beneath the relevant charts or sections.

Note: Values and interpretations depend on the hazards, exposed assets, vulnerability functions and model scope included in the underlying probabilistic risk model.
