Data collection

The FBI’s Uniform Crime Reporting (UCR) Program collects supplementary homicide data that provide the age, sex, and race of the murder victim and offender; the type of weapon used; the relationship of the victim to the offender; and the circumstance surrounding the incident. Statistics gleaned from these supplemental data are provided in this section.

This section also includes information about justifiable homicide—certain willful killings that must be reported as justifiable or excusable. In the UCR Program, justifiable homicide is defined as and limited to:

  • The killing of a felon by a peace officer in the line of duty.
  • The killing of a felon, during the commission of a felony, by a private citizen.

Because these killings are determined through law enforcement investigation to be justifiable, they are tabulated separately from murder and nonnegligent manslaughter. Justifiable homicide information can be found in Expanded Homicide Data Table 14, “Justifiable Homicide, by Weapon, Law Enforcement, 2010–2014” and Expanded Homicide Data Table 15, “Justifiable Homicide, by Weapon, Private Citizen, 2010–2014.”


  • In 2014, most (77.3 percent) of the 11,961 murder victims for whom supplemental data were received were male. (Based on Expanded Homicide Data Table 1)
  • Of the murder victims for whom race was known, 51.6 percent were black, 45.7 percent were white, and 2.6 percent were of other races. Race was unknown for 160 victims. (Based on Expanded Homicide Data Table 2)
  • Nearly 48 percent (47.7) of all murders for which the UCR Program received supplemental data were single victim/single offender situations. (See Expanded Homicide Data Table 4)
  • When the race of the offender was known, 53.0 percent were black, 44.7 percent were white, and 2.3 percent were of other races. The race was unknown for 4,132 offenders. (Based on Expanded Homicide Data Table 3)
  • Nearly 68 percent (67.9) of the homicides for which the FBI received weapons data in 2014 involved the use of firearms. Handguns comprised 68.5 percent of the firearms used in murder and nonnegligent manslaughter incidents in 2014. (Based on Expanded Homicide Data Table 8)
  • In 2014, nearly 29 percent (28.7) of homicide victims were killed by someone they knew other than family members (acquaintance, neighbor, friend, boyfriend, etc.), 14.3 percent were slain by family members, and 11.5 percent were killed by strangers. The relationship between murder victims and offenders was unknown in 45.5 percent of murder and nonnegligent manslaughter incidents. (Based on Expanded Homicide Data Table 10)
  • Of the female murder victims for whom the relationships to their offenders were known, 35.5 percent were murdered by their husbands or boyfriends. (Based on Expanded Homicide Data Tables 2 and 10)
  • Of the murders for which the circumstances surrounding the crimes were known, 40.4 percent of victims were murdered during arguments (including romantic triangles) in 2014. Felony circumstances (rape, robbery, burglary, etc.) accounted for 24.0 percent of murders. Circumstances were unknown for 37.7 percent of reported homicides. (Based on Expanded Homicide Data Table 11)
  • Law enforcement reported 721 justifiable homicides in 2014. Of those, law enforcement officers justifiably killed 444 felons, and private citizens justifiably killed 277 people during the commission of crimes. (See Expanded Homicide Data Tables 14 and 15)
