Percent of Offenses Cleared by Arrest or Exceptional Means
by Population Group, 2007

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.
This table furnishes national clearance data and clearances broken down by six city population groups, two county population groups, and suburban area.
This table lists the number of agencies meeting the criteria for inclusion in this table and the 2007 estimated population for those agencies by city grouping, county grouping, and suburban area.
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.
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 2007.
The FBI bases percent cleared statistics on aggregated offense and clearance totals.

Population groups

The UCR Program uses the following population group designations:

Population Group	Political Label	Population Range
I	City	250,000 and more
II	City	100,000 to 249,999
III	City	50,000 to 99,999
IV	City	25,000 to 49,999
V	City	10,000 to 24,999
VI	City^{1, 2}	Less than 10,000
VIII (Nonmetropolitan County)	County²	N/A
IX (Metropolitan County)	County²	N/A

¹Includes universities and colleges to which no population is attributed.
²Includes state police to which no population is attributed.

Population estimation

For the 2007 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 2006 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 2006 Census population estimate to derive the agency’s 2007 population estimate.
