social vulnerability index calculation

Validation of indices with external reference data has posed a persistent challenge in large part because social vulnerability is multidimensional and not directly observable. The Social Vulnerability Index (SoVI), created by Cutter et al. policy implications of being able to plot social vulnerability quantitatively and visu - ally are obvious, including for resource allocation, targeted interventions, and even disaster relief. Conclusion. The Social Vulnerability Index (SVI) employs U.S. Census Bureau variables to help users identify communities that may need support in preparing for hazards or recovering from disasters. 5. CDC’s Social Vulnerability Index (SVI) A tool to identify socially vulnerable communities CDC’s SVI What is social vulnerability? Social Vulnerability Index scores range from 0 to 1, which depicts the percentiles of a particular county or tract relative to the rest of the USA. But how reliable are the index rankings? Assessing Vulnerability to Climate Change: The Livelihood Vulnerability Index (LVI) In modeling the vulnerability to climate change by smallholder maize farming households, the balance weighted approach was employed by computing the LVI as developed by Hahn et al. 2.1. Index calculation and application ..... Index validation ... SoVI Social Vulnerability Index SVA Social Vulnerability Analysis UNDP United Nations Development Programme. The economic vulnerability index (EVI) was created in 2003 by Briguglio and Galea (2003) in order to assess the extent to which a country's economy is exposed to external and uncontrollable forces. Although there are many existing models that address the issue of social or socioeconomic vulnerability, there is no single model available that provides a landslide vul-nerability index for European communities. The higher the percentile ranking, the more vulnerable an area is … First, we conduct a PCA to calculate a PCA vulnerability index with 5 equal component weights based on prevalent literature. Second, we perform a regression analysis and use the coefcients as indicator weights for the calculation of a RA vulnerability index with explicit weighting. Hazards and Vulnerability Institute: Social Vulnerability in California by census tract. Social vulnerability indices have emerged over the past decade as quantitative measures of the social dimensions of natural hazards vulnerability. 2014, Midgley et al. Vulnerability, understood as the propensity to be adversely affected, has attained importance in the context of climate change by helping to understand what makes populations and territories predisposed to its impacts. Objectives Originally developed to assess emergency preparedness, evidence suggests the Social Vulnerability Index (SVI) may also be useful to investigate multilevel environmental and social influences on health risk behaviors and outcomes. The index is created by synthesizing socio-economic variables through a process called Index calculation includes a number of key index-construction decisions involving variable selection, normalization, weighting, and summarizing (Jones and Andrey, 2007).The present study analyses how decisions regarding weighting and summarizing influence the vulnerability outcome. The Social Vulnerability Index (SoVI) The SoVI, introduced by Cutter et al. NIEHS scientists led a collaborative effort to develop this COVID-19 Pandemic Vulnerability Index (PVI) Dashboard. You can then turn to the provided readings on calculation methods of social vulnerability and calculate the social vulnerability for particular hazards and groups of people in your area. Through such an index "diverse issues can be combined into a standardised framework...making comparisons possible". In this paper, a Rough AHP method for social vulnerability assessment was proposed and applied at county (urban district) level in Hanzhong City, China. economic vulnerability index (EVI). The social vulnerability index (SoVI) uses “initially 42 socio-economic variables, reduced to 11 statistically independent factors” (i.e. HAI and EVI are indices composed of five and eight indicators, respectively. Even so, older people’s social circumstances are complex and an approach which embraces this complexity is desirable. Social Vulnerability Index to Environmental Hazards Map for the United States – 32 Variables. The selection, collection, and pre-processing of data is the primary step in composite indicator development. The index was developed through consultation and collaboration with countries, institutions and experts across the globe. Conditions of vulnerability may vary depending on the characteristics of each territory studied—social, environmental, infrastructural, public policies, among … Alexander Fekete 2010: Assessment of Social Vulnerability for River-Floods in Germany 3 Abstract The assessment of social vulnerability unveils hidden weaknesses and strengths of the human society towards a certain stressor or hazard. Once compiled then … 2003). If you like. The calculation formula of IKS can be done by using two ways: equal weighted and unequal (2013). I hope you enjoyed learning about the concept of vulnerability, social vulnerability, and how to operationalize them. In the literature of environmental hazards and disaster management, quantitative assessments of social vulnerability have relied heavily on the “hazards-of-place” model of vulnerability, proposed by Cutter , which led to the Social Vulnerability Index (SoVI), an empirical relative measurement of the social vulnerability of places . Numerous social factors, generally studied in isolation, have been associated with older adults’ health. The Social Progress Index (SPI) measures the extent to which countries provide for the social and environmental needs of their citizens.Fifty-four indicators in the areas of basic human needs, foundations of well-being, and opportunity to progress show the relative performance of nations. 2011, Preston et al. Social Vulnerability: Susceptibility of social groups to the impacts of hazards such as disproportionate death, injury, loss, or disruption of livelihood • Social Vulnerability Index (SoVI) procured from HVRI-University of South Carolina Resilience: Ability to adequately recover from the impacts of hazards • BRIC - Nation-wide top-down index. Despite these caveats, the spatial vulnerability index construction methods described here are widely used in the literature and have been found to be useful to policy audiences seeking to better understand the factors contributing to vulnerability (e.g., Busby et al. This index is designed to be used with economic and social vulnerability indices to provide insights into the processes that can negatively influence the sustainable development of … (2009) and employed by Etwire et al. DFVI was made by analyzing the indicators’ relevance and by studying the main indicators needed to depict reality of the urban district floods in an effective way. 2013), but the calculation of the social vulnerability in quantitative terms still remains a compli-cated issue. Every community must prepare for and respond to hazardous events, whether a natural disaster like a tornado or disease outbreak, or a … This index is appropriate for urban district scaling (or: the urban district scale) and the various components of flood vulnerability (social, economic, environmental and physical). The data visualization in this dashboard offers an effective means of communicating data to scientists, policy makers, and the public. It is within this context that the starting point for measuring social vulnerability in South America was to capture pre-existing social conditions related to the overall capacity of populations to prepare for, respond to, and recover from damaging events. That might be one of the reasons why social vulnerability indexes still remains high in some counties even after 10-year disaster recovery efforts. age, race, ethnicity, education, family structure, social dependence, occupation) (Cutter et al. The index consists … EVI calculator. There are certain social factors that are directly related to a population’s vulnerability in the context of climate change. Thanks for watching. To be able to calculate an EVI requires the compilation of relevant environmental vulnerability data for the 50 indicators. Climate Vulnerability Index (CVI) is being proposed to assess climate change vulnerability of communities with a case study. We calculate two different social vulnerability indices. In this study, vulnerability is analysed in its relation to the hazard posed by extreme river-floods. 2011; Puissant et al. (2003), is a comparative metric that provides a snapshot of an area’s relative social vulnerability to a range of hazards. BACKGROUND SOCIAL VULNERABILITY ASSESSMENT TOOLS FOR CLIMATE CHANGE AND DRR PROGRAMMING 9 2011, BMZ 2014). The Social Vulnerability Index, originally formulated by Cutter et al. We find that we can validate the Rio de Janeiro heat vulnerability index against excess deaths during heat waves; specifically, we use three types of regressions coupled with difference in difference calculations to show this is indeed a heat vulnerability index as opposed to a social vulnerability index. Typically, the index is a composite of multiple quantitative indicators that via some formula, delivers a single numerical result. Social vulnerability refers to resilience, which is the ability to “bounce back.” Social vulnerability is a measure of how well communities may respond when confronted by external stresses on human health, natural or human-caused disasters or disease outbreaks. publications.
