The term Chicago is often used to refer to the sociology department of the University of Chicago, one of the oldest and most prestigious. The video uploaded by Mark Cambridge discusses the Chicago School and its role in classical criminology. According to Cambridge, he stated that: The Chicago School is an ecological approach to understanding crime, with ecology essentially meaning the relationship between different species and society at large (Cambridge). The ecological approach is an ecological systems theory developed by Urie Bronfenbrenner who believed that a person's development is affected by everything that happens in their environment. The Chicago School includes the Broken Window Theory which emphasizes the importance of disorder in generating and maintaining more serious crime. The broken windows theory is not directly linked to serious crime, but disorder leads to increased fear and withdrawal from residents. According to Wayne G. Lutters and Mark S. Ackerman, the Chicago School embraced many of the concerns of American sociology such as urban decay, crime, race relations, and the family, while adopting a more formal and systematic collection and analysis of data. There has been a tendency in Germany to produce a “science” of sociology (Lutters and Ackerman). The Chicago School was a distinct reaction against the state of American sociology of this period, and the Chicago School was shaped by the unique interests of its leading scholars. According to the Chicago Geographic Society, stated that: Influenced by the natural sciences, particularly evolutionary biology, members of the Chicago School proposed an ecological approach to sociology emphasizing the interaction between behavior human, social structures and the built environment (Chicago).
