The influences of incident and contextual characteristics on crime clearance of nonlethal violence: A multilevel event history analysis

Using multilevel event history analyses, this article investigates the effects of both incident and contextual (social disorganization and police resources) factors on crime clearance by arrest for robbery, forcible rape, and aggravated assault incidents in 106 cities. The analysis found that victim's age, the number of concomitant offenses and victims, victim's injury, and weapon use played important roles in crime clearance for all three types of nonlethal violent incidents. Among social disorganization variables, higher unemployment and racial segregation significantly decreased the odds of clearance for robbery and aggravated assault, but not for rape. Instead, higher divorce rates significantly decreased the odds of rape clearance. This suggests that social disorganization may play a different role in the clearance mechanisms for sexual than for nonsexual violent offenses. The effects of police resource variables on clearance were not significant in the expected direction for any of the three types of incidents.
