The Nation's Two Crime Measures

  • BJS's National Crime Victimization Survey (NCVS) - reported and unreported crime from the victim's perspective
  • FBI's Uniform Crime Reports (UCR) - crimes reported by law enforcement

Similar to many other indicators used to assess conditions in the United States, these two indicators of crime complement each other to produce a more comprehensive portrait of the nation's crime problem.

Some of the differences between UCR and NCVS are—

  UCR NCVS
Geographic coverage National and state estimates, local agency reports National estimates
Collection method Reports by law enforcement to the FBI on a monthly basis Survey data obtained from a nationally representative sample of about 240,000 interviews, which involves 160,000 unique persons in about 95,000 households.
Measures Index crimes* reported by law enforcement Reported and unreported crime; details about the crimes, victims, and offenders

*seven serious crimes

For more information about the purposes and advantages of the UCR and the NCVS, see The Nation's Two Crime Measures.
