The FBI’s Uniform Crime Reporting (UCR) Program defines murder and nonnegligent manslaughter as "the willful (nonnegligent) killing of one human being by another. The classification of this offense is based solely on police investigation as opposed to the determination of a court, medical examiner, coroner, jury, or other judicial body."
Source: The data used for statistics can be obtained from the FBI's Crime Data Explorer; Go to the Quarterly Uniform Crime Report tab to find this data.
The murder rate in city was calculated by dividing the number of murders and nonnegligent manslaughters by the city’s population and then multiplying 100,000.
Note: As of 2021, Charlotte is listed under Charlotte-Mecklenburg; Nashville is Metropolitan Nashville Police Department; Las Vegas is Las Vegas Metropolitan Police Department; Louisville is Louisville Metro.
