Social Vulnerability Indices and a Sub-municipal Index for Sweden

Abstract: The goal of risk and vulnerability research is to reduce the harm done by disasters. A disaster is a combination of a natural hazard and a vulnerable society. Understanding vulnerability is vital to reduce disaster risk, or the potential of losses in property or life. Vulnerability is often divided into a technical, relating to buildings, infrastructure, and so forth, and a social which concerns the way different groups in society differ in their ability to mitigate, prepare, respond and rebuild in the wake of a disaster. By exploring census data, an idea of where these vulnerable groups are located can be created and used to help them overcome barriers that prevent their preparedness. After an analysis of nineteen international studies focused on social vulnerability indices, a suggestion for a Swedish index is proposed. This Swedish index highlights thirteen indicators and seventeen variables that could be used to measure vulnerability in Sweden. National data sources for fifteen of the variables have been found and is presented. This index could be used to influence decision-making before a crisis by identifying those in need of additional assistance during the preparation and response phase of a disaster.
