Why does spatial inequality exist in urban areas

Spatial inequality or the uneven distribution of resources in a given space or territory is prevalent in urban areas because of the differences in income and wealth in differing parts of urban centers. Areas with more affluent residents tend to have cleaner air, safer neighborhoods, more greenery, larger living spaces, better schools and the list goes on. This is in comparison to poorer areas that are not as well served and deal with major inequalities. 

The constant presence of diseases or infectious agents within a given geographic area or population group. it may also refer to the usual prevalence of a given disease with such area or group. it includes holoendemic and hyperendemic diseases. a holoendemic disease is one for which a high prevalent level of infection begins early in life and affects most of the child population, leading to a state of equilibrium such that the adult population shows evidence of the disease much less commonly than do children (malaria in many communities is a holoendemic disease). a hyperendemic disease is one that is constantly present at a high incidence and/or prevalence rate and affects all groups equally. so probably family history.
