Since 1978, NIJ has been accumulating an archive of hundreds of data sets resulting from projects funded through research grant programs. NIJ partners with two other Office of Justice Programs agencies, the Bureau of Justice Statistics (BJS) and the Office of Juvenile Justice and Delinquency Prevention (OJJDP), to support the National Archive of Criminal Justice Data (NACJD). Currently housed at the Inter-University Consortium for Political and Social Research at the University of Michigan, NACJD provides access to a wide spectrum of data, including results from BJS and OJJDP survey series as well as original data from NIJ and OJJDP-funded research.
