Geographic Concentration Index
From Open Risk Manual
Definition
A Geographic Concentration Index is any mathematical function that converts a distribution of observed values along a geographical (spatial) domain into a single number expressing the prevalence (concentration) of observations amongst the total set. In the context of identifying Concentration Risk and Concentration Measurement geographic concentration indexes find applications in Geographic Concentration Measurement.
Geographic Concentration Indexes have been developed primarily in the context of assessing concentration of economic activity
Types of Indexes
- Generalizations of classic concentration indexes
- Indexes specifically developed for the incorporation of spatial domains (regions), which in turn can be decomposed into:
- Indexes that utilize predefined spatial domains (regions) as key abstraction
- Indexes that utilize spatial distances
