Download Data Declaration
The FBI collects these data through the Uniform Crime Reporting (UCR) Program.
General comments
- This table furnishes the number of violent and property crimes for which additional clearance data are available. These data are listed by six city population groups, two county groups, and suburban area.
- This table provides the following offense breakdowns and the percentages of those crimes cleared by arrest or exceptional means:
Forcible rape (by force and assault to rape-attempts)
Robbery and aggravated assault (weapon used)
Burglary (forcible entry, attempted forcible entry, and unlawful entry)
Motor vehicle theft (vehicle type)
Arson (property type)
- Not all agencies submit reports for arson to the FBI. As a result, the number of reports the FBI uses to compute the percent of offenses cleared for arson is less than the number it uses to compute the percent of offenses cleared for all other offenses.
- Agencies must report arson clearances by detailed property classification on the Monthly Return of Arson Offenses Known to Law Enforcement to be included in this table. However, not all agencies submit these supplemental data to the FBI; therefore, clearance data for arson in this table may differ from those in other clearance tables.
- This table lists the number of agencies and the 2005 estimated population in each city population group, county population group, and suburban area.
- Suburban area includes law enforcement agencies in cities with less than 50,000 inhabitants and county law enforcement agencies that are within a Metropolitan Statistical Area.
- Suburban area excludes all metropolitan agencies associated with a principal city. The agencies associated with suburban areas also appear in other groups within this table.
Methodology
- The data used in creating this table were from all law enforcement agencies submitting at least 6 months of complete offense reports for 2005.
- The FBI bases percent cleared statistics on aggregated offense and clearance totals.

Population estimation
The FBI calculated 2005 state growth rates using revised 2004 state/national population estimates and 2005 provisional state/national population estimates provided by the U.S. Census Bureau. The FBI then estimated population figures for city and county jurisdictions by applying the 2005 state growth rate to the updated 2004 U.S. Census Bureau data.
