The Source for Crime and Justice Data


NACJD is primarily sponsored by agencies within the U.S. Department of Justice. Each of our federal sponsors provides data collections to the archive, funds secondary analysis of criminal justice data, and sponsors educational workshops on quantitative methods of criminal justice research through NACJD.

  • The Bureau of Justice Statistics (BJS) collects, analyzes, publishes and disseminates information on crime, criminal offenders, victims of crime, and the operation of the justice systems at all levels of government.

  • The National Institute of Justice (NIJ) is the research and development agency established to prevent and reduce crime and to improve the criminal justice system. The NIJ Data Resources Program (DRP) collects, preserves, and disseminates data from NIJ grantees. DRP supports researchers using archived data in order to reproduce the original findings or test new hypotheses.

  • The Office of Juvenile Justice and Delinquency Prevention (OJJDP) provides national leadership, coordination and resources to prevent and respond to juvenile delinquency and victimization. OJJDP provides formula and block grants to states, territories and localities, as well as funding private organizations, including faith-based institutions through discretionary grants.

  • The Bureau of Justice Assistance (BJA) provides leadership and services in grant administration and criminal justice policy development to support local, state, and tribal justice strategies to achieve safer communities. BJA's overall goals are to (1) reduce and prevent crime, violence, and drug abuse and (2) improve the functioning of the criminal justice system. To achieve these goals, BJA programs emphasize enhanced coordination and cooperation of federal, state, and local efforts.

Additional support is received from the John D. and Catherine T. MacArthur Foundation, for the maintenance of the Project on Human Development in Chicago Neighborhoods (PHDCN) website and data. Researchers funded by the National Science Foundation are evaluating methods to encourage researchers to deposit data, using NACJD as a case study.

Parent Organization - ICPSR

NACJD was established in 1978 under the auspices of the Inter-university Consortium for Political and Social Research (ICPSR), which is part of the Institute of Social Research at the University of Michigan. ICPSR provides access to the world's largest archive of computer-readable social science data and offers training facilities in basic and advanced techniques of quantitative social analysis.

NACJD is one of several special topic archives at ICPSR. Special topic archives are funded by agencies external to ICPSR and focus on archiving data in specific subject areas. Most of the data collections in the special topic archives, including NACJD, are freely available to the public, whereas most ICPSR data collections are available only to ICSPR member institutions.

More information about ICPSR and data collections available through ICPSR can be found on the ICPSR website.
