Percent of Offenses Cleared by Arrest or Exceptional Means, by Region and Geographic Division, 2010

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

General comments

  • This table provides the number of violent crimes and property crimes with a breakdown of the offenses known to law enforcement and the percentage of those offenses that were cleared by arrest or exceptional means by region and geographic division. 
  • This table furnishes national clearance data and clearances broken down for the Nation’s four regions and nine geographic divisions. 
  • The number of agencies meeting the criteria for inclusion in this table and the 2010 estimated population for those agencies are provided by region and geographic division. 
  • 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. 

Methodology

  • The data used in creating this table were from all law enforcement agencies submitting at least 6 months of complete offense reports for 2010. 
  • 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. 

Regions and geographic divisions

Population estimation

For the 2010 population estimates used in this table, the FBI computed individual rates of growth from one year to the next for every city/town and county using 2000 decennial population counts and 2001 through 2009 population estimates from the U.S. Census Bureau. Each agency’s rates of growth were averaged; that average was then applied and added to its 2009 Census population estimate to derive the agency’s 2010 population estimate.
