The National Risk Index is a dataset and online tool to help illustrate the U.S communities most at risk for natural hazards. The Index leverages available source data for 18 natural hazards, social vulnerability, and community resilience to develop a baseline relative risk measurement for each U.S county and Census tract.

- Flood Exposure and Social Vulnerability
Flood exposure refers to valued societal elements (e.g., people, buildings) located in floodplains (de Moel et al. 2011; Koks et al. 2015). Analyzing flood exposure generally entails two steps: delineating the extent of flood hazard and aggregating the intersecting population and/or built environment assets. The primary source for delineating US fl...
Population estimates are valuable for defining the general severity of flood exposure, but such aggregated measures inform only how many people are exposed, not who. Disaggregating exposed populations is important because socially vulnerable populations disproportionately inhabit flood-prone areas (Platt 1998; Lee and Jung 2014). Root causes includ...
The spatial relationship between flood exposure and social vulnerability has often been studied using integrated analysis. Integrated studies develop and combine geospatial layers of multiple dimensions (e.g., physical, social, ecological) of natural hazards (Burton and Cutter 2008; Tate et al. 2010; Emrich and Cutter 2011; Rahman et al. 2016) to i...

Feb 6, 2024 · Some 230 million people in the United States face the potential of damaging earthquakes in 100 years, according to the latest U.S. National Seismic Hazard Model, or NSHM.
In a major upgrade to the beta version of the tool, released in 2016, this second version of the US Natural Hazards Index (NHI v2.0) helps visualize natural hazard data for fourteen hazard types in the United States and Puerto Rico (subject to data availability) at the census tract level.
POP1 Child population: Number of children (in millions) ages 0–17 in the United States by age, 1950–2022 and projected 2023–2050. NOTE: Some estimates have been revised since previous publication in America's Children.
USGS scientists and our partners recently revealed the latest National Seismic Hazard Model, showing that nearly 75% of the United States could experience a damaging earthquake, emphasizing seismic hazards span a significant part of the country.
