NIJ's Data Resources Program was established to ensure the preservation and availability of research and evaluation data collected through NIJ-funded research. Data sets collected through NIJ-funded research are archived and made available to others in order to support new research to replicate original findings or test new hypotheses. 

NIJ Data Collections and Activities are housed at the National Archive of Criminal Justice Data and maintained by the Inter-university Consortium for Political and Social Research

Together with the Bureau of Justice Statistics (BJS), NIJ's Data Resources Program supports the National Archive of Criminal Justice Data, which houses all data from NIJ sponsored research, and makes available online for downloading machine-readable copies (in SPSS, SAS or ASCII), together with data dictionaries and study abstracts. The archive is maintained by the Inter-university Consortium for Political and Social Research (ICPSR) at the University of Michigan.
