Established in 1978, the National Archive of Criminal Justice Data (NACJD) archives and disseminates data on crime and justice for secondary analysis. The archive contains data from over 2,700 curated studies or statistical data series. NACJD is home to several large-scale and well known datasets, including the National Crime Victimization Survey (NCVS), the FBI's Uniform Crime Reports (UCR), the FBI's National Incident-Based Reporting System (NIBRS), and the Project on Human Development in Chicago Neighborhoods (PHDCN).
In addition to making data available, NACJD curates and preserves data to ensure that they are accessible now and in the future. We also perform a number of outreach activities, including creating learning guides, hosting data workshops, and providing user support for our current and prospective data users and depositors.
Located within the Inter-University Consortium for Political and Social Research (ICPSR), a research center of the Institute for Social Research (ISR) at the University of Michigan, NACJD is sponsored by the Bureau of Justice Statistics (BJS), the National Institute of Justice (NIJ), and the Office of Juvenile Justice and Delinquency Prevention (OJJDP) of the United States Department of Justice.
