Programs & Research

NACJD is home to web sites for two separately maintained programs: the Project for Human Development in Chicago Neighborhoods (PHDCN) and the Homicide Research Working Group (HRWG).

The Project on Human Development in Chicago Neighborhoods (PHDCN) is a large-scale, 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 including the pathways to and away from juvenile delinquency, adult crime, substance abuse, and violence. At the same time, the project also provided a detailed look at the environments in which social behaviors take place by collecting substantial amounts of data about the people, institutions and resources of urban Chicago. Data has been turned over to NACJD for the ongoing process of archiving and dissemination.

The Homicide Research Working Group (HRWG), an interdisciplinary and international association of researchers and policy makers, was formed in 1991 to foster communication, coordination, and networking among people involved in the study of homicide. NACJD has been a frequent host for HRWG meetings and ICPSR maintains the HRWG Web site, which provides information on HRWG news, meetings, membership, and publications.
