Social disorganization is a theoretical framework for analyzing and assessing the relationship between social structure, social control, and criminal activity, which includes behaviors such as linguistic integration and immigration into communities. There are two prevalent approaches to social disorganization theory. The earlier approach defined social disorganization in terms of minimal social control reflecting socioeconomic disadvantage and ethnic group heterogeneity (multiple ethnicities in a community). The newer one defines social disorganization as the convergence of conflicting cultural standards resulting in the emergence of criminal behavior in social groups associated with socioeconomically disadvantaged neighborhoods (Andres F. Rengifo, "Social Disorganization").
Many articles exist on the topic of social disorganization and are accessible from libraries that your school code can give you online access to. Two articles are readily accessible online, free to read. One is by Oxford Bibliographies, Andres F. Rengifo, defining the field and providing a bibliography of works on the topic. The other is hosted by National Center for Biotechnology Information (NCBI) and posted on HHS Public Access by Ramiro Martínez, Jr, Richard Rosenfeld, and Dennis Mares. There is no recommended length for articles you use for research purposes, although your essay may have a required word-length limit.
