NIJ, in partnership with theBureau of Justice Statistics (BJS) and theOffice of Juvenile Justice and Delinquency Prevention (OJJDP), is seeking proposals under the Data Resources Program (DRP) for original research using existing data available from theNational Archive of Criminal Justice Data (NACJD) and other public sources. NACJD houses quantitative and qualitative data from research funded by these three agencies. The data are made available online at no cost as downloadable, machine-readable files. Copies of documentation, such as user guides and codebooks, are also available at no charge. NACJD is maintained by the Inter-University Consortium for Political and Social Research at the University of Michigan and is supported by NIJ, BJS, and OJJDP. Highest priority will be given to research that addresses compelling crime and criminal justice questions involving juvenile and adult populations, and that uses NIJ, BJS, or OJJDP data at NACJD.
