Climate change presents major socioeconomic threats to Small Island Developing States (SIDS). To better understand the impacts of environmental hazards to SIDS we employ a Social Vulnerability Index (VI) based on publicly available national level data from the United Nations’ various organizations. We employ a principle component factor method to both socioeconomic and demographic data to island nations in the Africa, Caribbean, and Pacific Regions to better understand their vulnerabilities to potential hazard. This method allows for the determination of the appropriate variables that measures a SIDS’ vulnerability, as compared to similar nations. The study also seeks to identify individual country level vulnerabilities as well as regional comparative vulnerabilities. Another objective of this research to help develop a robust framework to better understand VI within island nations to increase their resilience to various hazard, and to help such nations better collect and monitor factors that may contribute to vulnerability.
