General comments

  • This table provides the types of weapons used in robbery offenses. The data are based on the aggregated data from agencies within each state for which weapon information was reported to the FBI. The table includes the number of agencies that submitted data by state and the population covered by those agencies.
  • The FBI received limited weapon data from the Illinois state UCR Program.

Methodology

  • The data used in creating this table were from all law enforcement agencies that submitted complete offense reports for 12 months in 2013.
  • The weapon totals are aggregated from all robbery offense data for which the FBI received weapon breakdowns.

Population estimation

For the 2013 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 2010 decennial population counts and 2011 through 2012 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 2012 Census population estimate to derive the agency’s 2013 population estimate.
