In 1915, Robert E. Park and E. W. Burgess introduced the idea of "neighborhood" as an ecological concept with urban planning implications . Since then, many concepts and ideas of a neighborhood have emerged. Milton Kolter defines a neighborhood as, “…a political settlement of small territory and familiar association, whose absolute property is its capacity for deliberative democracy.” While most neighborhoods are difficult to define geographically, anyone who lives in an urban setting relates to an area that they call their neighborhood. As such, it is a useful level to engage in planning practice.
