National Survey of Tribal Court Systems (NSTCS)

​​​​​​The legal institutions in Indian country revolve around four main entities: indigenous or traditional courts, general jurisdiction courts, appellate courts, and the Bureau of Indian Affair’s Code of Federal Regulation courts. The National Survey of Tribal Court Systems (NSTCS) is the first complete enumeration of tribal court systems operating in the United States and gathers administrative and operational information from tribal court systems, prosecutors’ offices, and indigent defense providers operating in the United States.

Tribal Crime

To improve the availability of data on crime in Indian country, BJS creates data tables containing information reported by tribal law enforcement agencies to the FBI's Uniform Crime Reporting (UCR) Program and published in the annual Crime in United States (CIUS) publication.

Federal Justice System

BJS maintains multiple data collections covering various aspects of the federal justice system encompassing law enforcement, prosecution, courts, and corrections. BJS data collections range from censuses of law enforcement and annual deaths in custody to federal case processing statistical information, describing the number of suspects/defendants from arrest to imprisonment.
