The Project on Human Development in Chicago Neighborhoods (PHDCN) is an interdisciplinary study of how families, schools, and neighborhoods affect child and adolescent development. It was designed to advance the understanding of the developmental pathways of both positive and negative human social behaviors. In particular, the Project examined the pathways to juvenile delinquency, adult crime, substance abuse, and violence. At the same time, the Project also provided a detailed look at the environments in which these social behaviors take place by collecting substantial amounts of data about urban Chicago, including its people, institutions, and resources.
The Project's design consisted of two major components. The first was an intensive study of Chicago's neighborhoods, particularly the social, economic, organizational, political, and cultural structures and the dynamic changes that take place in the structures over time. The second component was a series of coordinated longitudinal studies that followed over 6,000 randomly selected children, adolescents, and young adults to examine the changing circumstances of their lives and the personal characteristics that might lead them toward or away from a variety of antisocial behaviors.

The PHDCN data and research materials were processed by the National Archive of Criminal Justice Data (NACJD) at the University of Michigan's Inter-university Consortium for Political and Social Research (ICPSR). A three-year award from the John D. and Catherine T. MacArthur Foundation supported the initial archiving of PHDCN data and two summer workshops to train researchers in how to use these data. The National Institute of Justice provides continued support to maintain and further enhance the Project through an interagency cooperative agreement with NACJD.
The NACJD staff are making this large and complex data collection easily accessible to the research community by:
