Percent Change, by Population Group

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

General comment

This table provides the percent change in offenses known to law enforcement, by population group, for the first six months of 2018 and 2019.

Important note about rape data

In 2013, the FBI’s UCR Program initiated the collection of rape data under a revised definition within the Summary Reporting System. The term “forcible” was removed from the offense name, and the definition was changed to “penetration, no matter how slight, of the vagina or anus with any body part or object, or oral penetration by a sex organ of another person, without the consent of the victim.”

In 2016, the FBI Director approved the recommendation to discontinue the reporting of rape data using the UCR legacy definition beginning in 2017.

Methodology

The data used in creating this table were from law enforcement agencies submitting three to six common months of offense reports for 2018 and 2019. If the FBI determines certain variables have created unusual fluctuations in the data, those data are excluded from the tabulations.

The rape data reported using the UCR legacy definition for either 2018, 2019, or both years are not included in the rape percent change.

Population estimation

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.
