![]() Indeed, Dynes (2002) asserts that one’s risk perception is developed via social networks and, with this, one is then motivated to act by taking preventative action. For example, several studies have examined the effect of social connections and social support in encouraging individuals and families to evacuate with the issuance of a storm warning ( Dash and Gladwin 2007 Gladwin et al. Within this realm, the role of social capital, specifically in the form of family ties and friendships, has gained growing attention. Sociobehavioral and sociocultural indicators in particular have been a concentrated area of focus in the scholarly literature, resulting in an accumulation of knowledge that spans nearly 40 years ( Baker 1979, 1991, 1995 Dow and Cutter 1998, 2000 Sherman-Morris et al. There are a myriad of factors that affect evacuation decision making from concern over the geophysical hazards of the storm, such as the winds and storm surge, to social elements including age, gender, and race. This study has important implications for adding to the knowledge base on community-based sustainable disaster preparedness and resilience. On the other hand, the perceived dependability of a person’s social connections (i.e., their perceived access to resources and support) did not significantly impact the decision to evacuate for Hurricane Irma. Through statistical analyses, it was concluded that density and diversity of people’s social networks played a significant role in the decision to evacuate or not, with evacuees having more dense and diverse relationships. To collect accurate ephemeral decision-making data from evacuees, the surveys were completed during the evacuation for those who evacuated and shortly after the passage of Hurricane Irma for those who did not evacuate. These variables, together with socioeconomic variables (e.g., race/ethnicity, age, education), were considered in order to better explain the influences on evacuation decision-making. ![]() Using Hurricane Irma in September 2017 as a case study, a survey was conducted on two groups (those who evacuated and those who did not evacuate) to assess people’s social connections specifically examining three dimensions: dependability, density, and diversity. ![]() ![]() This study investigates the influence of individuals’ social connections in their decision to either evacuate or not evacuate in the days preceding the landfall of Hurricane Irma. ![]()
