Description
CDC SVI measures community vulnerability to help emergency response planners and public health officials identify and map communities that will most likely need support before, during, and after a hazardous event.
SoVI® measures a county's ability to prepare for, respond to, and recover from hazards in relation to other counties in that state and across the nation.
FEMA CRCI aggregate indicator provides a relative assessment of a community's potential challenges to resilience.
BRIC describes the differences in community resilience among counties within the state and within the nation.
FEMA NRI illustrates a community's potential vulnerability and resilience based on exposure (expected annual loss) to 18 natural hazards.
Output
CDC SVI provides a vulnerability score between 0 (least vulnerable) to 1 (most vulnerable):
SoVI® provides a comparative social vulnerability score that enables users to:
FEMA CRCI provides a relative assessment of a community's potential resilience and gives insights into community characteristics from which to build emergency operations plans and targeted outreach strategies.
BRIC provides a comparative community resilience score that enables users to:
FEMA NRI provides an overall risk percentage as well as individual risk percentages for 18 of the USA's most common natural hazards.
