Indicators

Indicators: Vulnerability needs to be reflected through indicators. An indicator, or set of indicators, can be defined as an inherent characteristic which quantitatively estimates the condition of a system; they usually focus on small, manageable, tangible and telling piece of a system that can give people a sense of the bigger picture.

The vulnerability indicators should provide additional information to set more precise and quantitative targets for vulnerability reduction. System indicators facilitate the analysis of the relative state of the overall system and they should reflect the socio-economic, environmental and physical condition of the geographic region.
