Segregation
Spatial segregation can be understood as the disproportionate distribution of various elements or types across individual parts of a larger area. It is said to be disproportionate because the spatial distribution of a group (or the use of a resource) does not correspond to that of another group. The elements and types in question can encompass social classes, ethnic groups, religious groups or indeed doctors with different specialisations or different types of housing; it can also refer to the use of resources.
