The INFORM Risk Index 2021 is a composite model structured into a hierarchy of dimensions, categories, and components. All scores are normalized on a scale of 0 to 10 (10 being the highest risk).Below is the clear breakdown of the index's architecture based on your descriptions:The Composite IndexThe top-level score representing a country's overall risk of humanitarian crisis. It is used to assign countries into Risk Classes:Low: ≤3.5Medium: 3.5−5.0High: 5.0−6.5Very High: ≥6.5Dimension: VulnerabilityThis dimension measures the predisposition of a population to be affected by a hazard based on economic, political, and social characteristics.Sub-Index: Socio-Economic VulnerabilityAn aggregate index covering three main components of systemic instability:Development Deprivation: Measures poverty using the Human Development Index (HDI) and Multidimensional Poverty Index (MPI).Inequality: Captures the dispersion of human development, including the Gender Inequality Index and the Gini Coefficient.Aid Dependency: Measures economic instability through reliance on public aid, development assistance, and remittances.Sub-Index: Vulnerable GroupsCaptures social groups with limited access to care and heightened susceptibility:Uprooted People: Tracks refugees, IDPs, and returnees.Children Under 5: Specifically monitors child malnutrition and mortality rates.Recent Shocks: Factors in populations already affected by natural disasters in the last 3 years.Food Security: Captures trends in chronic hunger and nutritional balance.Health Conditions: Monitors the prevalence of pandemics (HIV, TB, Malaria) and neglected tropical diseases.Dimension: Lack of Coping CapacityThis dimension measures the ability of a country to manage and recover from disasters through its infrastructure and government effort.Sub-Index: Institutional CapacityMeasures the "soft" infrastructure of a country's disaster management:Governance: Captures government effectiveness, resilience-building, and political integrity (lack of corruption).DRR Implementation: Quantifies how well Disaster Risk Reduction activities are actually put into practice.Sub-Index: InfrastructureMeasures the "hard" assets and systems available during a crisis:Communication: Evaluates the efficiency of early warning dissemination and the literacy/education of the recipients.Physical Connectivity: Assesses the accessibility of transport and the quality/availability of water and sanitation services.Access to Healthcare: Captures health system strength, including physician density and maternal/infant health services.
