Number of Offenses Cleared by Arrest or Exceptional Means, Percent of Clearances Involving Persons Under 18 Years of Age by Population Group, 2011

The FBI collects these data through the Uniform Crime Reporting (UCR) Program.

General comments

  • This table provides the number of clearances for violent crimes and property crimes with a breakdown of clearances for those offenses as well as the percentage of those clearances that involved only juveniles.
  • The number of agencies meeting the criteria for inclusion in this table and the 2011 estimated population for those agencies are provided by city population groups, county population groups, and suburban areas.
  • Suburban areas include law enforcement agencies in cities with less than 50,000 inhabitants and county law enforcement agencies that are within a Metropolitan Statistical Area.
  • Suburban areas exclude all metropolitan agencies associated with a principal city.  The agencies associated with suburban areas also appear in other groups within this table.
  • When an offender under the age of 18 is cited to appear in juvenile court or before other juvenile authorities, the UCR Program considers the incident to be cleared by arrest, even though a physical arrest may not have occurred.
  • Clearances for offenses that include both adult and juvenile offenders are classified as clearances for crimes committed by adults and are, therefore, not included in this table.
  • Because the clearance percentages for crimes committed by juveniles include only those clearances in which no adults were involved, the figures in this table should not be used to present a definitive picture of juvenile involvement in crime.
  • Not all agencies submit data reports for arson to the FBI. Therefore, the agency counts and estimated population presented in this table do not represent participation for the reporting of arson.

Methodology

  • The data used in creating this table were from all law enforcement agencies submitting at least 6 months of complete offense reports for 2011.
  • The FBI bases percent cleared statistics on aggregated offense and clearance totals.  The percentage of crimes cleared by arrest is obtained first by dividing the number of offenses cleared by the number of offenses known and then multiplying the resulting figure by 100.

Population estimation

The FBI calculated 2011 state growth rates using the U.S. Census Bureau’s 2010 decennial state/national population figures and 2011 provisional state/national population estimates.  The FBI then estimated population figures for city jurisdictions by applying the 2011 state growth rate to the 2010 U.S. Census Bureau data.
