Programs & Research

NACJD is home to websites for two separately maintained programs: the Project for Human Development in Chicago Neighborhoods (PHDCN) and the Terrorism and Preparedness Data Resource Center (TPDRC).

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.

The Terrorism and Preparedness Data Resource Center (TPDRC) archives and distributes data collected by government agencies, non-governmental organizations (NGOs), and researchers about the nature of intra- (domestic) and international terrorism incidents, organizations, perpetrators, and victims; governmental and nongovernmental responses to terror, including primary, secondary, and tertiary interventions; and citizen's attitudes towards terrorism, terror incidents, and the response to terror. It also organizes and streamlines access to extant research and administrative data from across the world that are relevant to the study of terrorism and the response to terrorism for descriptive and scientific analysis by academics and researchers.
