Weather and climate disasters are becoming more frequent, wide-ranging, severe, and costly. While consequences for life and health are always at the forefront, one way to measure disaster impact is through estimates of economic impacts. The National Oceanic and Atmospheric Administration (NOAA) estimates that from 2019 to 2023, the U.S. experienced more than 100 $1 billion disasters, with total costs in excess of $0.5 trillion. This is four times the average number of $1 billion disasters and more than double the costs of any other five-year period since 2000. In 2023 alone, there were 28 $1 billion disasters, the highest number recorded since 1980 (when data became available). And these disasters affected 46 states, almost twice the number of states affected by $1 billion disasters in 2000. Indeed, the number of states experiencing $1 billion disasters has steadily risen year over year since 2000.

More and worsening disasters across a broader swath of the country means more lives and livelihoods placed in harm’s way and more communities likely facing intertwined economic and social consequences. Given current trends, state and local leaders are seeking ways to help their communities recover and rebuild effectively in the wake of disaster, restoring not only infrastructure and homes but economic competitiveness and social well-being. To help inform state and local recovery planning efforts, we examined quantitative and anecdotal evidence from U.S. communities that have demonstrated robust resilience in the face of disasters—what we termed leading recoveries—as well as for communities that experienced lower resilience where we saw lagging recoveries.

Experiencing a single disaster - a hurricane, tornado, flood, severe winter storm, or a global pandemic - can wreak havoc on the lives and livelihoods of individuals, families, communities and entire regions. For many people who live in communities in the U.S. Gulf of Mexico region, the reality of disaster is starker. Endemic socioeconomic and health disparities have made many living in Gulf of Mexico communities particularly vulnerable to the effects of weather-climate hazards. Prolonged disaster recovery and increasing disaster risk is an enduring reality for many living in Gulf of Mexico communities. Between 2020 and 2021, seven major hurricanes and a severe winter storm affected communities across the region. As a backdrop to these acute weather events, the global COVID-19 pandemic was unfolding, producing a complex and unprecedented public health and socioeconomic crisis.

Traditionally, the impacts of disasters are quantified individually and often in economic terms of property damage and loss. In this case, each of these major events occurring in the Gulf of Mexico during this time period subsequently earned the moniker of "billion-dollar" disaster. However, this characterization does not reflect the non-financial human toll and disparate effects caused by multiple disruptive events that increase underlying physical and social vulnerabilities, reduce adaptive capacities and ultimately make communities more sensitive to the effects of future disruptive events. This report explores the interconnections, impacts, and lessons learned of compounding disasters that impair resilience, response, and recovery efforts. While Compounding Disasters in Gulf Coast Communities, 2020-2021 focuses on the Gulf of Mexico region, its findings apply to any region that has similar vulnerabilities and that is frequently at risk for disasters.
