Abstract
Research has revealed that crime tends to concentrate in families and that it also tends to be transmitted across generational lines. The current study expanded on this line of research by examining the familial concentration and transmission of crime in a sample of sibling pairs. Analysis of data drawn from the National Longitudinal Study of Adolescent Health (Add Health) revealed that 5% of all families accounted for more than 50% of all criminal arrests. Additional analyses revealed between-sibling similarity and intergenerational transmission in being arrested, being sentenced to probation, being incarcerated, and being arrested multiple times. Structural equation models (SEMs) were also estimated to examine the mechanisms that might account for the familial concentration and transmission of crime. These SEMs provided evidence indicating that the concentration and transmission of crime was due, in part, to genetic factors as well as mating patterns.
