Vulnerability Index

The map presents an assesment of social and economic vulnerability of populations residing in coatsal flood hazard areas in Israel.

Social vulnerability is measured by a composite index that encompasses the leading variables likely to affect a households socio-economic status and thereby its life chances of recovery. Vulnerability is comprised of exposure (exogenous) and resilience (endogenous).

Four key social variables are used to define vulnerability at the spatial resolution of the statistical area. These are average income, disabilities, age groups and number of vehicles per household. We divide the national distribution of each indicator into quintiles (1- least vulnerable, 5-most vulnerable) and assign each statistical area to its respective class. The weighted composite index is devised as follows: Ivul = Ii*0.5 + Id*0.2 + Ia*0.2 + Iv*0.1
where: Ivul = the composite vulnerability index, Ii = income quintile, Id = disability quintile, Ia = age quintile, Iv = vehicle quintile.
