Social disorganization theory is considered as one of the most important theories in criminology in terms of its focus on the affect of social environment on delinquency or crime. However, it ignores the impact of child development and family management on juvenile delinquency which are crucial on juveniles' life trajectories. Hence, extended version of the social disorganization theory (ecological theory in criminology) considered mediating effects of child development and family management. Bronfenbrenner's Ecological theory also seeks to explain human development by emphasizing environmental along with individualistic factors because human ecology theory perceives humans as both biological organism and social beings who have interaction with their environment. Therefore, the purpose of this study is to explain the ways that Bronfenbrenner's ecological theory increase our capacity to understand or do research on delinquency or crime by comparing similarities and differences with ecological theory in criminology.
