According to the United States Department of Justice, Office of Juvenile Justice Delinquency Prevention Juvenile Justice Bulletin, June 2000
Kidnapping makes up less than 2 percent of all violent crimes against juveniles reported to police.
Based on the identity of the perpetrator, there are three distinct types of kidnapping: kidnapping by a relative of the victim or "family kidnapping" (49 percent), kidnapping by an acquaintance of the victim or "acquaintance kidnapping" (27 percent), and kidnapping by a stranger to the victim or "stranger kidnapping" (24 percent).
Family kidnapping is committed primarily by parents, involves a larger percentage of female perpetrators (43 percent) than other types of kidnapping offenses, occurs more frequently to children under 6, equally victimizes juveniles of both sexes, and most often originates in the home.
Acquaintance kidnapping has features that suggest it should not be lumped with stranger kidnapping into the single category of non-family kidnapping, as has been done in the past.
Acquaintance kidnapping involves a comparatively high percentage of juvenile perpetrators, has the largest percentage of female and teenage victims, is more often associated with other crimes (especially sexual and physical assault), occurs at homes and residences, and has the highest percentage of injured victims.
Stranger kidnapping victimizes more females than males, occurs primarily at outdoor locations, victimizes both teenagers and school-age children, is associated with sexual assaults in the case of girl victims and robberies in the case of boy victims (although not exclusively so), and is the type of kidnapping most likely to involve the use of a firearm.
