| NOTE: This rate is the ratio of the number of crimes (aggravated assault, rape, and robbery [i.e., stealing by force or threat of violence]) reported to the National Crime Victimization Survey for which the age of the offenders was known, plus the number of homicides reported to police that involved at least one juvenile offender perceived by the victim (or by law enforcement in the case of homicide) to be 12–17 years of age, to the number of juveniles in the population. Because of changes made in the victimization survey, data prior to 1992 are adjusted to make them comparable with data collected under the redesigned methodology. Rates may also be revised to reflect final U.S. Census Bureau population estimates for 1990–2005. | ||||||||||||||||||||||||||
