Sociodemographic factors associated with heatwave risk perception in the United States
Extreme heat events are one of the deadliest weather-related hazards in the United States and are increasing in frequency and severity due to anthropogenic greenhouse gas emissions. Further, some subpopulations may be more vulnerable than others due to social, economic, and political factors that create disparities in hazard impacts and responses. Vulnerability is also affected by risk perceptions, which can influence protective behaviors. In this study, we use national survey data to investigate the association of key sociodemographic factors with public risk perceptions of heat waves. We find that risk perceptions are most associated with income, race/ethnicity, gender, and disability status. Age, an important predictor of heat mortality, had smaller associations with heat risk perceptions. Low-income, non-white, and disabled individuals tend to perceive themselves to be at greater risks from heat waves than other subpopulations, corresponding with their elevated risk. Men have lower risk perceptions than women despite their higher mortality and morbidity from heat. This study helps to identify subpopulations in the U.S. who see themselves as at risk from extreme heat and can inform heat risk communication and other risk reduction practices.
期刊介绍:
Weather, Climate, and Society (WCAS) publishes research that encompasses economics, policy analysis, political science, history, and institutional, social, and behavioral scholarship relating to weather and climate, including climate change. Contributions must include original social science research, evidence-based analysis, and relevance to the interactions of weather and climate with society.
