Research, Statistics & Evaluation

Research is critical to the development of sound criminal justice policy, as well as to the development of advanced technologies that support the work of law enforcement agencies. Sound evaluations of methods and existing OJP grant programs are necessary to ensure the wise expenditure of taxpayer dollars. As the research, development, and evaluation agency of the Department of Justice, the National Institute of Justice is dedicated to improving knowledge and understanding of crime and justice issues through science. NIJ provides objective and independent knowledge and tools to reduce crime and promote justice, particularly at the state and local levels.

Research and OJP's Offices and Bureaus

The Office of Justice Programs (OJP) includes multiple offices and bureaus that either directly support research, statistics, and evaluation, or regularly use this information to support programming, training, and related activities.

Statistics

The Bureau of Justice Statistics (BJS) is the primary statistical agency of the U.S. Department of Justice. BJS collects, analyzes, publishes, and disseminates information on crime, criminal offenders, victims of crime, and the operation of justice systems at all levels of government. Impartial, timely, and accurate statistical data are essential to guide and inform federal, state, and local policymaking on crime and the administration of justice and to improve the quality of and access to information used for decision making. The BJS website provides every publication released by BJS since 1995, with downloadable datasets and spreadsheets, online analytic capabilities, and graphical presentations.

Evidence Integration

Children Exposed to Violence (CEV)

Children may experience crime, violence, and abuse in their homes, in school, and in their communities, and these experiences accumulate over time. Whether a child is a direct victim or a witness to violent events, childhood exposure to violence has been demonstrated to cause a range of subsequent difficulties and challenges for the individuals themselves, as well as for families and communities. Understanding and addressing children exposed to violence (CEV) requires a multi-disciplinary approach that is not limited by the specific nature or location of the violence or the relationship of the parties involved.

This review and synthesis of evidence related to CEV reveals that CEV: (1) affects a significant number of children in the United States; (2) may have significant negative outcomes, particularly when children are exposed to multiple forms of violence; and (3) is related to a variety of known risk factors. In addition to specific evidence-based programs that can be found on CrimeSolutions.gov, this review identified characteristics associated with successful practices.

Gangs

Gangs continue to be a major issue of concern because of the violence and other criminal and delinquent activity they bring to localities across the country. Generally, practitioners and researchers agree that success in responding to gangs requires an appropriate balance of effective prevention, intervention, enforcement, and reentry activities. In addition to the specific evidence-based programs that can be found on CrimeSolutions.gov, this review examines the nature of gang activity in the United States and practices used to address them.

OJP's Evidence Integration Initiative (E2I)

OJP’s Evidence Integration Initiative (E2I) is focused on improving the synthesis and translation of social science research findings to inform practice and policy in criminal justice, juvenile justice, and victim services. OJP’s CrimeSolutions.gov accomplishes this primarily by assessing the quality and findings of program evaluation evidence to try to answer the question "does this program work?" See CrimeSolutions.gov to access research on program effectiveness reviewed and rated by CrimeSolutions.gov researchers and reviewers.

The OJP Diagnostic Center is the next component of E2I, helping state, local, and tribal leaders apply what works in criminal justice in their communities by providing diagnosis and customized courses of action based on proven, evidence-based programs and practices. For more information, visit the OJP Diagnostic Center website.
