Citizens with different demographic characters presented varying responses and behaviors in the same disasters. Their divergent responses can impact their actual damages during crises. Previous studies have employed social media for analyzing citizens’ crisis responses. However, these studies missed the demographic dimension. To resolve this limitation, this research proposes three objectives: 1) to explore the variances of sentiment polarities among different racial/ethnic and gender groups; 2) to investigate the concern themes in their expressions, including theme popularity and their sentiment towards these themes; 3) to enhance the understanding of social aspects of disaster resilience with the results of disaster response disparities. Results indicate that Hispanic and male groups are more likely to express negative sentiment. The black group pays the least attention to ‘hurricane warn’ and shows most interests in ‘pray/donate’. The white group is most optimistic about hurricane/flood impacts while the black group shows dissatisfaction towards ‘response’. The female group pays less attention to ‘hurricane warn’ while they are more optimistic towards ‘hurricane/flood impact’ and ‘response’ than the male group. Our findings can help crisis response managers identify the more sensitive/vulnerable groups in the crisis and provide on-target disaster evolution reports and relief resources to the corresponding demographic groups.

具有不同人口统计学特征的公民在相同的灾难中表现出不同的反应和行为。他们的不同反应会在危机期间影响他们的实际损失。先前的研究使用社交媒体来分析公民的危机应对。但是，这些研究错过了人口维度。为了解决这一局限性，本研究提出了三个目标：1）探索不同种族/族裔和性别群体之间的情感极性差异。2）调查主题表达中的关注主题，包括主题受欢迎程度及其对这些主题的看法；3）借助灾难响应差异的结果，加深对灾难复原力的社会方面的了解。结果表明，西班牙裔和男性群体更有可能表达负面情绪。黑人团体对“飓风警告”的关注最少，对“祈祷/捐赠”的兴趣最大。白人对飓风/洪水影响最为乐观，而黑人则对“响应”表示不满。女性群体对“飓风警告”的关注较少，而男性群体则对“飓风/洪水影响”和“响应”更为乐观。我们的发现可以帮助危机应对经理确定危机中更敏感/更脆弱的群体，并向相应的人口群体提供针对性的灾难演变报告和救灾资源。女性群体对“飓风警告”的关注较少，而男性群体则对“飓风/洪水影响”和“响应”更为乐观。我们的发现可以帮助危机应对经理确定危机中更敏感/更脆弱的群体，并向相应的人口群体提供针对性的灾难演变报告和救灾资源。女性群体对“飓风警告”的关注较少，而男性群体则对“飓风/洪水影响”和“响应”更为乐观。我们的发现可以帮助危机应对经理确定危机中更敏感/更脆弱的群体，并向相应的人口群体提供针对性的灾难演变报告和救灾资源。
