2017年的飓风哈维和伊尔玛为研究疏散行为的人口统计学和经验预测因素提供了机会，包括飓风之间的不同因素。2017年12月14日至21日，822名受访者完成了调查，包括与疏散相关的人口统计和经验变量。调查对象包括飓风哈维期间疏散的德克萨斯州12个县，飓风艾玛期间疏散的佛罗里达州23个县和佐治亚州27个邮政编码。年轻人和与孩子一起生活的人更有可能撤离。感知到的风险和先前的创伤与疏散有关，但飓风经历与疏散无关。在两个逻辑回归中，接收疏散命令的频率和感知风险仍然是重要的预测因子，包括他人疏散程度的主观和客观度量。讨论了理论和政策影响。
Hurricanes Harvey and Irma in 2017 provided opportunities to study demographic and experiential predictors of evacuation behavior, including factors that differ between hurricanes. A Qualtrics panel targeted the 12 Texas counties evacuated during Hurricane Harvey, and the 23 Florida counties and 27 Georgia ZIP codes evacuated during Hurricane Irma. 822 respondents completed the survey 14-21 December 2017, including demographic and experiential variables related to evacuation. Younger adults and those who lived with children were more likely to evacuate. Perceived risk and previous trauma were associated with evacuation, but hurricane experience was not. In two logistic regressions, frequency of receiving evacuation orders and perceived risk remained as significant predictors, including subjective and objective measures of the degree to which others evacuate. Theoretical and policy implications are discussed.
