Percent of Offenses Cleared by Arrest or Exceptional Means
Additional Information About Selected Offenses
by Population Group, 2007
The FBI collected these data through the Uniform Crime Reporting (UCR)
Program.
General comments
- This table provides offense breakdowns and the percentages of those
crimes cleared by arrest or exceptional means for the following offenses:
- 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)
- These data are listed by six city population groups, two county groups,
and suburban area.
- Agencies must report clearances for specific offense breakdowns on
either the Return A or 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 in this table may differ from those in other clearance
tables.
- 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.
- 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.
- 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.

| II |
City |
100,000 to 249,999 |
| III |
City |
50,000 to 99,999 |
| IV |
City |
25,000 to 49,999 |
| V |

10,000 to 24,999 |
| VI |
City1, 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.
