Disaster vulnerability is typically assessed in physical and economic terms, with social dimensions largely ignored. However, there has been growing demand among disaster planners and stakeholders to incorporate social vulnerability, which measures the sensitivity of population groups to hazard impacts. The dominant approaches for measuring social vulnerability generalize it across all environmental hazards, but there also is a need for hazard-specific indicators. This research synthesizes the social vulnerability literature to identify which social dimensions are relevant to flood hazards. Socio-demographic indicators representing these dimensions are collected and processed into a social vulnerability index using factor analysis. The index is mapped and compared to the all-hazards index to assess the differences.
