The National Archive of Criminal Justice Data (NACJD) is the place to discover, access, and analyze data on crime and justice.
NACJD hosts several large-scale datasets, including the National Crime Victimization Survey (NCVS), the FBI's Uniform Crime Reports (UCR), the FBI's National Incident-Based Reporting System (NIBRS), and the Project on Human Development in Chicago Neighborhoods (PHDCN).
