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):

  • Describes areas in which the community is most socially vulnerable to disasters
  • Easily drill down into variables behind the social vulnerability scoring

SoVI® provides a comparative social vulnerability score that enables users to:

  • Compare the social vulnerability among counties within the state and within the nation
  • Compare or track social vulnerability changes over time

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:

  • Compare the community resilience among counties within the state and within the nation
  • Compare or track community resilience changes over time

FEMA NRI provides an overall risk percentage as well as individual risk percentages for 18 of the USA's most common natural hazards.

Variables Overview


(for more detailed analysis of variables, please visit the Variables Comparison Chart)

16 social factors from four main types of variables:

  • Socioeconomic Status
  • Household Characteristics
  • Race & Ethnic Minority Status
  • Housing Type & Transportation

29 socioeconomic variables that contribute to a reduction in a community’s ability to prepare for, respond to, and recover from hazards.

22 indicators:

  • 11 that are population-focused
  • 9 that are community-focused

6 broad categories of community disaster resilience:

  • Social
  • Economic
  • Community Capital
  • Institutional
  • Infrastructural
  • Environmental

FEMA NRI incorporates three datasets:

  • CDC SVI
  • BRIC
  • Expected Annual Loss
