What do I mean by vulnerability Vulnerability: the potential for loss Vulnerability is a function of exposure, sensitivity, & adaptive capacity Has both physical & social components Social vulnerability - the product of social stratification & inequalities - Access to resources - Function of the demographics of the population (age, race, sex, etc.) - More complex constructs (health care, social capital, limited political & economic power, etc.) Introduction Previous Research Current Research Future Research
