In late March, FEMA will release major updates to the National Risk Index. Updates will include Census 2020 data and geographies, risk assessment for U.S. territories, Centers for Disease Control and Prevention (CDC) Social Vulnerability data, shifting all scores to percentiles, adding risk metrics for trend analyses and more. The National Risk Index shows the communities most at risk to 18 natural hazards. It is a key tool to helping communities better learn and reduce their risk and can support mitigation planning, community preparedness and emergency management.
