The changing demography of hurricane at-risk areas in the United States (1970-2018)

Hurricanes have proven to be one of the most deadly and costly natural hazards in the Gulf and Atlantic coast regions of the United States. Looming climate change and increasing population in coastal areas means these hazards could become even more devastating in the future. This paper first develops estimates of areas most impacted by hurricane flooding and wind damage and then assesses the generalised patterns of demographic change in those at-risk locations, disaggregating by both race and age to account for the complex shifts in demographic composition that have occurred over the past five decades. We find evidence of racial, ethnic, and age disparities in exposure to hurricane flooding and wind impacts. Our results highlight not only the uneven burden of risk placed on those unable or unwilling to move, but also the structural privilege that enables the white population to remain in place, even in the face of increased hurricane damage risk.
