See: Comparative Glossary (Conclusions): Together with vulnerability and hazard exposure is another pre-requisite of risk and disaster. Here, exposure is understood as the number of people and/or other elements at risk that can be affected by a particular event. In an uninhabited area the human exposure is zero. No matter how many hurricanes will affect an uninhabited island, the human exposure, and hence the risk of human loss, remains zero. While the vulnerability determines the severity of the impact an event will have on the elements at risk, it is the exposure that drives the final tally of damage or harm. So in its economic dimension, vulnerability is depicted by the projection that, in a given event, a family will probably lose 50% of its assets. How many families will be affected and lose 50% of their assets is captured by the exposure. In an overly simplified example, the poverty of a community will determine the degree to which it will be affected by an event of a certain magnitude (à susceptibility) and the number of the community members represents the exposure. In that sense a densely populated area is at higher risk then a sparsely populated one, all other conditions being equal
