Crime Trends, by Suburban and Nonsuburban Cities by Population Group,
2011-2012

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

General comments

• This 2-year trend table provides the number of offenses for 2011 and 2012 and the percent change between these 2 years for suburban and nonsuburban cities.
• Suburban cities include law enforcement agencies in cities with less than 50,000 inhabitants that are within a Metropolitan Statistical Area (MSA) but exclude all metropolitan agencies associated with a principal city.
• Nonsuburban cities include law enforcement agencies in cities with less than 50,000 in population that are not associated with an MSA.

Methodology

• The data used in creating this table were from all law enforcement agencies submitting at least 6 common months of complete offense reports for 2011 and 2012.
• A crime trend represents the percentage change in crime based on data reported in a prior equivalent period. In calculating trends, the UCR Program includes only common reported months for individual agencies.

Population estimation

The FBI calculated 2012 state growth rates using the U.S. Census Bureau’s 2011 and 2012 provisional state/national population estimates. The FBI then estimated population figures for city and county jurisdictions by applying the 2012 state growth rate to the updated 2011 U.S. Census Bureau data.
