13The term known offender does not imply that the identity of the suspect is known, but only that a characteristic of the suspect has been identified, which distinguishes him/her from an unknown offender.
14Law enforcement may report a range of ages. NIBRS reports the midpoint of the age range (e.g., offender age 25-35 is reported as 30).
15UCR race reporting guidelines for NIBRS Data Element #39–Race (of offender) follow the minimally accepted standards established by OMB Directive 15. The NIBRS guidelines can be found in NIBRS Volume 1: Data Collection Guidelines, Federal Bureau of Investigation, August 2000, p. 100.

17These three items are collected jointly in the NIBRS. Refer to p. 38 of the UCR Handbook, NIBRS Edition, Federal Bureau of Investigation, 1992, for a detailed explanation and examples of how these items could be used in the perpetration of a crime.

19Weapon types are only reported for murder and nonnegligent manslaughter, negligent homicide, justifiable homicide, kidnapping, forcible rape, forcible sodomy, sexual assault with an object, forcible fondling, robbery, aggravated assault, extortion, and weapon law violations. UCR Handbook, NIBRS Edition, Federal Bureau of Investigation, 1992.
20Summing the gun categories will not yield the number of incidents with guns as there may be more than one gun type in an incident. For example, an incident may have involved the use of a rifle and a shotgun.
21The Other weapon type is an umbrella category that captures weapon types not reflected in the specific weapon type definitions.
22One or more of the offenders may have used the type indicated and one or more offenders may have used more than one type in the same offense. It should also be noted that if an offender used a type in an incident with multiple offenses, its use will be counted in the table more than once.
23Law enforcement may report a range of ages. NIBRS reports the midpoint of the age range (e.g., offender age 25-35 is reported as 30).
24These data were not tested for validity and are presented as they are found in the NIBRS database. Please see the Limitations section for more details.
