Podsumowanie	The Social Vulnerability Index (SVI) measures how vulnerable a community is to the harmful effects of disasters and public-health emergencies, based on the social and economic characteristics of the people who live there. The CDC/ATSDR version, introduced by Flanagan and colleagues in 2011, percentile-ranks census variables, groups them into themes (socioeconomic status, household composition and disability, racial and ethnic minority status and language, and housing type and transportation), and aggregates them into an overall ranking for each census tract or county. It builds on the broader social-vulnerability concept developed by Cutter, Boruff, and Shirley, whose 2003 Social Vulnerability Index to environmental hazards (SoVI) used factor analysis to show that susceptibility to disaster losses is socially patterned. The SVI is widely used to plan disaster response, allocate resources, and target public-health interventions toward the communities least able to cope.	The allostatic load index quantifies the cumulative biological cost of chronic stress by summing dysregulation across multiple physiological systems. McEwen and Stellar introduced 'allostatic load' in 1993 to name the wear and tear the body accrues when stress-response systems are repeatedly or chronically activated, extending the idea of allostasis (stability through change) over time. Seeman, Singer, Rowe, Horwitz, and McEwen operationalized it in the MacArthur Studies of Successful Aging in 1997, scoring older adults on biomarkers spanning cardiovascular, metabolic, neuroendocrine, and immune function and counting how many fell into a high-risk range, typically the worst quartile. The resulting count index predicted later cognitive and physical decline and cardiovascular disease, establishing allostatic load as a measurable marker of cumulative physiological risk that no single clinical test captures.
