Standardizing the Display of IBR Data: Weapon Variables
Tables Presented by the FBI
In the FBI's preliminary tables using NIBRS, data were used to illustrate NIBRS content and capabilities by providing simple, easy to understand tables and charts. One table uses Weapon Type to demonstrate the frequency of the use of weapons in violent offenses.
Number of Offenses Known by Weapon, Selected Offenses, 1998
|Offense||Number of Offenses||Firearms||Dangerous Weapons||Personal Weapons||Firearms with Dangerous and/or Personal Weapons||Other Weapon Combinations||Unk||None|
|Kidnapping / Abduction||4,133||600||407||1,823||53||71||240||939|
|Other Forcible Sex Offenses||16,212||57||610||9,969||17||94||852||4,613|
To create this table, weapons were grouped into categories. Firearms include the presence of at least one firearm, handgun, rifle, or shotgun. Dangerous weapons include knives, clubs, blunt objects, and all weapons other than personal weapons (hands, fists, feet). Combinations of different types of weapons were also included for comparison. Firearms are reported as the weapon most frequently used in murders and robberies, but personal weapons are more often recorded for forcible sex offenses and kidnapping.
