Standardizing the Display of IBR Data: Injury Variables
Data Collection and Quality Issues Associated with Injury Variables
Injuries at a Glance
|Required?||For some offenses|
|Number of Entries?||5|
|Number of Coding Options?||8|
According to the FBI Data Collection Guidelines, the injury variable describes the type(s) of bodily injury suffered by an individual who was the victim of one or more of the following offenses:
|11A||Forcible Rape||13A||Aggravated Assault|
|11B||Forcible Sodomy||13B||Simple Assault|
|11C||Sexual Assault With An Object||210||Extortion/Blackmail|
When one of these offenses occurs, up to five entries can be made for each victim. There are 8 allowable entries:
|N||None||M||Apparent Minor Injury|
|B||Apparent Broken Bones||O||Other Major Injury|
|I||Possible Internal Injury||T||Loss of Teeth|
Data Quality Issues
Injury data can be used to determine whether weapon type is correctly coded. When an injury occurs, there should be a weapon involved. When a table is produced that compares these injuries with the weapon type, however, we can see that this isn't always the case.
As we can see from the table, 238,976 injuries were reported, yet for 20,318 of them, the reported weapon type is None.

Note: Please check that the variable names used in this syntax match the variable names in your data file. If you need assistance, contact JRSA.
As was discussed in the Weapons section, injuries can also be used to determine whether assaults without a weapon are accurately coded. For further discussion, please visit the Weapon Data Element section.
