Most of our data come from studies sponsored by NIJ, OJJDP, or BJS. If you wish to deposit data from a project sponsored by any of those agencies, please go to the Share Data page and select the appropriate option.
We also accept data from other sources. For more information about including your data in the NACJD and ICPSR collections, please email us at firstname.lastname@example.org.
