Rate: Number of Crimes per 100,000 Inhabitants
by Suburban and Nonsuburban Cities by Population Group, 2007

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

General comments

This table provides the rate per 100,000 inhabitants and the number of offenses known to law enforcement for violent crime (murder and nonnegligent manslaughter, forcible rape, robbery, and aggravated assault) and property crime (burglary, larceny-theft, and motor vehicle theft) in suburban and nonsuburban cities. In addition, the table furnishes the number of agencies meeting the criteria for inclusion in this table and provides the estimated population for each city group.
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 suburban and nonsuburban cities classifications in this table encompass all cities other than principal cities served by municipal law enforcement agencies in Metropolitan Statistical Areas (MSAs).
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.

Methodology

The data used in creating this table were from all law enforcement agencies submitting 12 months of complete data (except arson) for 2007.
The FBI derived the offense rates by first dividing the total aggregated offense estimates 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.

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.
