Introduction
In 2000, law enforcement agencies in the United States made an estimated 2.4 million arrests of persons under age 18.* According to the Federal Bureau of Investigation (FBI), juveniles accounted for 17% of all arrests and 16% of all violent crime arrests in 2000. The substantial growth in the number of juvenile violent crime arrests that began in the late 1980s peaked in 1994. In 2000, for the sixth consecutive year, the rate of juvenile arrests for Violent Crime Index offenses—murder, forcible rape, robbery, and aggravated assault—declined. Specifically, between 1994 and 2000, the juvenile arrest rate for Violent Crime Index offenses fell 41%. As a result, the juvenile violent crime arrest rate in 2000 was the lowest since 1985. The juvenile murder arrest rate fell 74% from its peak in 1993 to 2000, when it reached its lowest level since at least the 1960s.
These findings are derived from data reported annually by local law enforcement agencies across the country to the FBI's Uniform Crime Reporting (UCR) Program. Based on these data, the FBI prepares its annual Crime in the United States report, which summarizes crimes known to the police and arrests made during the reporting calendar year. This information is used to characterize the extent and nature of juvenile crime that comes to the attention of the justice system. Other recent findings from the UCR Program include the following:
- Of the nearly 1,600 juveniles murdered
in 2000, 38% were under 5 years of age,
68% were male, 52% were white, and
52% were killed with a firearm.
- Juveniles were involved in 9% of murder
arrests, 14% of aggravated assault arrests,
33% of burglary arrests, 25% of
robbery arrests, and 24% of weapons
arrests in 2000.
- Juvenile murder arrests increased substantially between 1987 and 1993. In
the peak year of 1993, there were about 3,800 juvenile arrests for murder.
Between 1993 and 2000, juvenile arrests for murder declined, with the
number of arrests in 2000 (1,200) less than one-third that in 1993.
- Juvenile arrest rates for burglary
declined 63% between 1980 and 2000.
- Between 1990 and 2000, the juvenile
proportion of all arrests for drug abuse
violations increased from 8% to 13%.
- Juvenile arrests for curfew and loitering
violations increased 81% between 1991
and 2000. In 2000, 28% of curfew arrests
involved juveniles under age 15 and
31% involved females.
- In 2000, 59% of arrests for running away
from home involved females and 39%
involved juveniles under age 15.
- Arrests of juveniles accounted for 12% of all violent crimes cleared by arrest in 2000—specifically, 5% of murders, 12% of forcible rapes, 16% of robberies, and 12% of aggravated assaults.

What do arrest statistics count? To interpret the material in this Bulletin properly, the reader must have a clear understanding of what these statistics count. The arrest statistics report the number of arrests made by law enforcement agencies in a particular year�not the number of individuals arrested, nor the number of crimes committed. The number of arrests is not equivalent to the number of people arrested because an unknown number of individuals are arrested more than once in the year. Nor do arrest statistics represent counts of crimes committed by arrested individuals because a series of crimes committed by one individual may culminate in a single arrest, or a single crime may result in the arrest of more than one person. This latter situation, where many arrests result from one crime, is relatively common in juvenile law-violating behavior because juveniles are more likely than adults to commit crimes in groups. This is the primary reason why arrest statistics should not be used to indicate the relative proportion of crime committed by juveniles and adults. Arrest statistics are most appropriately a measure of flow into the criminal and juvenile justice systems. Arrest statistics also have limitations for measuring the volume of arrests for a particular offense. Under the UCR Program, the FBI requires law enforcement agencies to classify an arrest by the most serious offense charged in that arrest. For example, the arrest of a youth charged with aggravated assault and possession of a controlled substance would be reported to the FBI as an arrest for aggravated assault. Therefore, when arrest statistics show that law enforcement agencies made an estimated 203,900 arrests of young people for drug abuse violations in 2000, it means that a drug abuse violation was the most serious charge in these 203,900 arrests. An unknown number of additional arrests in 2000 included a drug charge as a lesser offense.
What do clearance statistics count? Clearance statistics measure the proportion of reported crimes resolved by an arrest or other, exceptional means (e.g., death of the offender, unwillingness of the victim to cooperate). A single arrest may result in many clearances. For example, 1 arrest could clear 40 burglaries if the person was charged with committing all 40 of these crimes. Or multiple arrests may result in a single clearance if the crime was committed by a group of offenders. For those interested in juvenile justice issues, the FBI also reports information on the proportion of clearances attributed to the arrest of persons under age 18. This statistic is a better indicator of the proportion of crime committed by this age group than is the arrest proportion, although some concerns exist that even the clearance statistic overestimates the juvenile proportion of crimes. For example, the FBI reports that persons under age 18 accounted for 25% of all robbery arrests but only 16% of all robberies cleared in 2000. If it can be assumed that offender characteristics of cleared robberies are similar to those of robberies that were not cleared, then it would be appropriate to conclude that persons under age 18 were responsible for 16% of all robberies in 2000. However, the offender characteristics of cleared and noncleared robberies may differ for a number of reasons. If, for example, juvenile robbers were more easily apprehended than adult robbers, the proportion of robberies cleared by the arrest of persons under age 18 would overestimate the juvenile responsibility for all robberies. To add to the difficulty in interpreting clearance statistics, the FBI�s reporting guidelines require the clearance to be tied to the oldest offender in the group if more than one person is arrested for a crime. In summary, while the interpretation of reported clearance proportions is not straightforward, these data are the closest measure generally available of the proportion of crime known to law enforcement that is attributed to persons under age 18. |
