About Us

ResearchDataGov.org is a product of the federal statistical agencies and units, created in response to the Foundations of Evidence-based Policymaking Act of 2018. The site is the single portal for discovery of restricted data in the federal statistical system. The agencies have provided detailed descriptions of each data asset. Users can search for data by topic, agency, and keywords. Questions related to the data should be directed to the owning agency, using the contact information on the page that describes the data. In late 2022, users will be able to apply for access to these data using a single-application process built into ResearchDataGov. ResearchDataGov.org is built by and hosted at ICPSR at the University of Michigan, under contract and guidance from the National Center for Science and Engineering Statistics within the National Science Foundation.

The data described in ResearchDataGov.org are owned by and accessed through the agencies and units of the federal statistical system. Data access is determined by the owning or distributing agency and is limited to specific physical or virtual data enclaves. Even though all data assets are listed in a single inventory, they are not necessarily available for use in the same location(s). Multiple data assets accessed in the same location may not be able to be used together due to disclosure risk and other requirements. Please note the access modality of the data in which you are interested and seek guidance from the owning agency about whether assets can be linked or otherwise used together.

Agency Profile

Bureau of Justice Statistics

The Bureau of Justice Statistics (BJS) mission is to collect, analyze, publish, and disseminate information on crime, criminal offenders, victims of crime, and the operation of justice systems at all levels of government. BJS collects data on courts, crime type, jails and inmates, prisons and prisoners, probation and parole, capital punishment, justice-related employment and expenditures, law enforcement, tribal areas, and victims. BJS also directs and supports the National Crime Statistics Exchange (NCS-X) and efforts to improve criminal justice data and records for states and localities.

BJS allows eligible individuals the opportunity to apply for access through the SAP Portal for restricted data files housed at the Federal Statistical Research Data Centers (FSRDCs) and the National Archive of Criminal Justice Data (NACJD). All restricted-use data requestors must submit an application for approval.

All BJS public-use files (PUF) continue to be available from NACJD at ICPSR. BJS data tools, data tables, and statistical reports are available on the BJS website.
