The UCR Program collects information on crimes reported by law enforcement agencies regarding the violent crimes of murder and non-negligent manslaughter, rape, robbery, and aggravated assault, as well as the property crimes of burglary, larceny-theft, motor vehicle theft, and arson. (Although the FBI classifies arson as a property crime, it does not estimate arson data because of variations in the level of participation by the reporting agencies. Consequently, arson data are not included in the property crime estimate.) The program also collects arrest data for the offenses listed above plus 20 offenses that include all other crimes except traffic violations.
The revised UCR definition of rape is “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.
For the 2015 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 2014 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 2014 Census population estimate to derive the agency’s 2015 population estimate.
In 2013, the UCR Program initiated the collection of rape data under a revised definition and removed the term “forcible” from the offense name. The UCR Program now defines rape as follows:
Rape (revised definition): 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. (This includes the offenses of rape, sodomy, and sexual assault with an object as converted from data submitted via the National Incident-Based Reporting System.)
Rape (legacy definition): The carnal knowledge of a female forcibly and against her will.

Rounding off of values was applied in the Total Percent Distributions for Violent Crimes and Property Crimes, so the percentages may not add to 100.0.
For legend #2
The rape figures in this table are aggregate totals of the data submitted based on both the legacy and revised Uniform Crime Reporting definitions.
For legend #3
Violent crimes are offenses of murder and nonnegligent manslaughter, rape, robbery, and aggravated assault. Property crimes are offenses of burglary, larceny-theft, motor vehicle theft, and arson.
