Table 5 Data Declaration
Crime in the United States, by State, 2018
The FBI collects these data through the Uniform Crime Reporting (UCR) Program.
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.
- This table provides the estimated number of offenses and the rate of crime per 100,000 inhabitants for each state.
- This table provides the estimated number of offenses and the actual number of offenses reported in Metropolitan Statistical Areas, cities outside metropolitan areas, nonmetropolitan counties, the rate (per 100,000 inhabitants) for each community type, and the estimated population for each state.
- Violent crime includes the offenses of murder and nonnegligent manslaughter, rape (revised definition), robbery, and aggravated assault. Property crime includes the offenses of burglary, larceny-theft, and motor vehicle theft.
- The UCR Program does not have sufficient data to estimate for arson.
Caution against ranking
Any comparisons of crime among different locales should take into consideration relevant factors in addition to the area’s crime statistics. UCR Statistics: Their Proper Use provides more details concerning the proper use of UCR statistics.
- The data used in creating this table were from all law enforcement agencies in the UCR Program (including those submitting less than 12 months of data).
- Crime statistics include estimated offense totals (except arson) for agencies submitting less than 12 months of offense reports for each year.
- The statistics under the heading “Area actually reporting” represent offense totals for agencies submitting 12 months of data and estimated totals for agencies submitting less than 12 but more than 2 months of data.
- The statistics in the table under the heading “Estimated total” represent the above “Area actually reporting” plus estimated totals for agencies submitting 2 months or less of data.
- The rape data reported by those agencies using the UCR legacy definition are not included in this table.
These tables contain statistics for the entire United States. Because not all law enforcement agencies provide data for complete reporting periods, the FBI includes estimated crime numbers in these presentations. The FBI computes estimates for participating agencies not providing 12 months of complete data. For agencies supplying 3 to 11 months of data, the national UCR Program estimates for the missing data by following a standard estimation procedure using the data provided by the agency. If an agency has supplied less than 3 months of data, the FBI computes estimates by using the known crime figures of similar areas within a state and assigning the same proportion of crime volumes to nonreporting agencies. The estimation process considers the following: population size covered by the agency; type of jurisdiction, e.g., police department versus sheriff’s office; and geographic location.
In response to various circumstances, the FBI has estimated offense totals for some states. For example, problems at the state level (e.g., noncompliance with UCR guidelines, technological difficulties) have, at times, resulted in data that cannot be used for publication, and estimation was necessary. Also, efforts by an agency to convert to NIBRS have contributed to the need for unique estimation procedures.
A summary of state-specific and offense-specific estimation procedures is available in the “Estimation of state-level data” section of the Methodology.
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.
