Adolescents with siblings who have committed crimes are more likely to be influenced by their siblings and become delinquent if the sibling is older, of the same sex/gender, and maintains a good relationship with the child. Cases where a younger criminal sibling influences an older one are rare. An aggressive more hostile sibling is less likely to influence a younger sibling in the direction of delinquency, if anything, the more strained the relationship between the siblings, the less they will want to be influence each other.
