The aim is to develop a targeted social vulnerability index for assessing community vulnerability to water service disruptions.
Developed a water-specific social vulnerability index using 21 relevant factors grouped into health-related, socioeconomic, and housing-related vulnerabilities.
Applied principal component analysis to reduce dimensionality and constructed the index via Pareto ranking.
Compared the new index with FEMA’s existing social vulnerability index to highlight differences.
Counties ranked as low or moderate vulnerability in FEMA’s index were identified as highly vulnerable in the new analysis.
Key factors impacting vulnerability included aging infrastructure, high rental occupancy, and inadequate plumbing not captured by FEMA’s index.
