Abstract
As a concept, social vulnerability describes combinations of social, cultural, economic,
political, and institutional processes that shape socioeconomic differentials in the experience
of and recovery from hazards. Quantitative measures of social vulnerability are
widely used in research and practice. In this paper, we establish criteria for the evaluation
of social vulnerability indicators and apply those criteria to the most widely used measure
of social vulnerability, the Social Vulnerability Index (SoVI). SoVI is a single quantitative
indicator that purports to measure a place’s social vulnerability. We show that SoVI
has some critical shortcomings regarding theoretical and internal consistency. Specifically,
multiple SoVI-based measurements of the vulnerability of the same place, using the same
data, can yield strikingly different results. We also show that the SoVI is often misaligned
with theory; increases in variables that contribute to vulnerability, like the unemployment
rate, often decrease vulnerability as measured by the SoVI. We caution against the use of
the index in policy making or other risk-reduction efforts, and we suggest ways to more
reliably assess social vulnerability in practice.
