Rate: Number of Crimes per 100,000 Inhabitants
by Metropolitan and Nonmetropolitan Counties by Population Group, 2009
The FBI collects these data through the Uniform Crime Reporting (UCR) Program.
- This table provides the rate per 100,000 inhabitants and the number of offenses known to law enforcement for violent crimes (murder and nonnegligent manslaughter, forcible rape, robbery, and aggravated assault) and property crimes (burglary, larceny-theft, and motor vehicle theft) for metropolitan and nonmetropolitan county law enforcement agencies submitting 12 months of complete data (except arson) for 2009. In addition, the table furnishes the number of agencies meeting the criteria for inclusion in this table and provides the estimated population for each population group.
- Metropolitan counties include sheriffs’ offices and county law enforcement agencies associated with a Metropolitan Statistical Area (MSA).
- Nonmetropolitan counties include sheriffs’ offices and county law enforcement agencies that are not associated with an MSA.
- Offenses reported by state police agencies are not included in this table.
- The FBI publishes only data that conform to UCR data collection guidelines. For example, the data collection methodology for the offense of forcible rape used by the state UCR Programs administered by the Illinois State Police and the Minnesota Department of Public Safety do not comply with these guidelines, and, therefore, are not available for inclusion in this table. Instead, the FBI computes the rates by estimating forcible rape offenses for each population group for participating agencies in Illinois and Minnesota. The figures are estimated using the national rates for each population group applied to the population by group for Illinois and Minnesota agencies supplying 12 months of complete data.
- The UCR Program does not have sufficient data to publish arson offenses in this table. Information about arson can be found in Arson Tables 1 and 2.
- The data used in creating this table were from all law enforcement agencies submitting 12 months of complete data (except arson) for 2009.
- The FBI derived the offense rates by first dividing the aggregated offense counts by the aggregated populations covered by contributing agencies for which 12 months of complete data were supplied and then multiplying the resulting figure by 100,000.
The UCR Program uses the following population group designations:
||250,000 and more
||100,000 to 249,999
||50,000 to 99,999
||25,000 to 49,999
||10,000 to 24,999
||Less than 10,000
|VIII (Nonmetropolitan County)2
|IX (Metropolitan County)2
1Includes universities and colleges to which no population is attributed.
2Includes state police to which no population is attributed.
For the 2009 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 2008 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 2008 Census population estimate to derive the agency’s 2009 population estimate.
