This document provides an overview of social disorganization theory, which proposes that criminal behavior is influenced by sociological factors and the environment. The theory was developed by the Chicago School, which found correlations between crime rates and conditions of poverty like inadequate housing and a lack of economic opportunities. Social disorganization theory specifically suggests that a breakdown in social controls and community structure in disadvantaged neighborhoods leads to increased crime and delinquency, as factors like poverty, residential mobility, and ethnic heterogeneity weaken social ties and support networks.
