Table 22 Data Declaration
Aggravated Assault, by State, Types of Weapons, 2018
The FBI collects these data through the Uniform Crime Reporting (UCR) Program.
- This table provides the types of weapons used in aggravated assault 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 weapons data from the Illinois state UCR Program.
- The data used in creating this table were from all law enforcement agencies that submitted complete offense reports for 12 months in 2018.
- The weapon totals are aggregated from all aggravated assault offense data for which the FBI received weapon breakdowns.
For the 2018 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 2017 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 2017 Census population estimate to derive the agency’s 2018 population estimate.
