Risk = the Probability of something happening X resulting Cost/Consequences Probably the most frequently used definition of risk is this one: With these factors, even if a community experiences a large-scale event, its risk may be relatively low overall if it has a highly resilient population, a relatively low overall frequency of hazards, etc.Your preferred source of resilience information Community risk in The Index is a combination of several factors, including the expected annual dollar loss related to building value, population, or agriculture value due to a natural hazard social vulnerability, represents the susceptibility of social groups to the adverse impacts of natural hazards and community resilience, measures the ability of a community to prepare for anticipated natural hazards, adapt to changing conditions, and withstand and recover rapidly from disruptions. The National Risk Index identifies a community’s risk to natural hazards. My community had a large-scale event recently but does not show up as “high risk.” Why not? While this tool can be one source of information to support risk reduction investments, other information and tools (e.g., a benefit-cost analysis or local knowledge) should also be considered. The National Risk Index is intended to inform risk-based decision making while increasing risk awareness. Should I prioritize risk reduction funding directly based on the National Risk Index?

Disaster aid experience: The number of presidential disaster declarations divided by the number of loss-causing events.

Flood insurance coverage: Percentage of housing units covered by National Flood Insurance Program policies.

Mitigation spending: 10-year average per capita spending for mitigation projects.

The community resilience component ( Baseline Resilience Indicators for Communities) includes the following information: Many of these decisions are made at a state level, influenced by funding availability, and have qualifying levels. How does the NRI align with historic FEMA funding? Have “high-risk areas” traditionally received the most funds for mitigation, public assistance, individual assistance, presidential declaration, preparedness grants, etc.? A regionally significant hazard has the capacity to cause widespread, catastrophic damage, like a hurricane, tsunami, or volcanic activity and profiled by fewer than 25 state hazard mitigation plans. Natural hazards included in at least 50% of the state hazard mitigation plans, or those that were considered regionally significant were selected. How were hazards selected for the National Risk Index? It is a great alternative for communities that do not have access to mapping services, since it uses authoritative data from a variety of contributors. The National Risk Index is different from other traditional models because it analyzes 18 natural hazard types, in addition to a community’s social vulnerability, community resilience, to provide a more holistic view of risk.

Why do I need another tool to prioritize areas of risk? How is the NRI different? See more answers to frequently asked questions on the National Risk Index website.

With this data, you can discover a holistic view of community risk to natural hazards.Īccess the National Risk Index How to Use the National Risk Index

The National Risk Index's interactive web maps are at the county and Census tract level and made available via geographic information system (GIS) services for custom analyses. The National Risk Index is a new, online mapping application from FEMA that identifies communities most at risk to 18 natural hazards. This application visualizes natural hazard risk metrics and includes data about expected annual losses from natural hazards, social vulnerability and community resilience.
