Table containing authoritative violent crime values for Sioux Falls, South Dakota.

Abstract (en): This data collection contains county-level counts of arrests and offenses for Part I offenses (murder, rape, robbery, aggravated assault, burglary, larceny, auto theft, and arson) and counts of arrests for Part II offenses (forgery, fraud, embezzlement, vandalism, weapons violations, sex offenses, drug and alcohol abuse violations, gambling, vagrancy, curfew violations, and runaways). ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection: Standardized missing values.; Performed recodes and/or calculated derived variables.; Checked for undocumented or out-of-range codes.. County law enforcement agencies in the United States. 2006-03-30 File CB2389.ALL.PDF was removed from any previous datasets and flagged as a study-level file, so that it will accompany all downloads.2005-11-04 On 2005-03-14 new files were added to one or more datasets. These files included additional setup files as well as one or more of the following: SAS program, SAS transport, SPSS portable, and Stata system files. The metadata record was revised 2005-11-04 to reflect these additions.2001-02-16 A correction was made to the formula for calculating the Coverage Indicator listed in the ICPSR Data Collection Description section of the codebook.1998-09-17 Parts 4 and 8 were reprocessed to correct four records that indicated that no agencies had reported data, but which actually contained crime data. Changes affect the variables AG_OFF and COVIND in each data file. Funding insitution(s): United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics. (1) Two major changes to the Uniform Crime Reports (UCR) county-level files were implemented beginning with the 1994 data. A new imputation algorithm to adjust for incomplete reporting by individual law enforcement jurisdictions was adopted. Within each county, data from agencies reporting 3 to 11 months of information were weighted to yield 12-month equivalents. Data for agencies reporting less than 3 months of data were replaced with data estimated by rates calculated from agencies reporting 12 months of data located in the agency's geographic stratum within their state. Secondly, a new Coverage Indicator was created to provide users with a diagnostic measure of aggregated data quality in a particular county. Data from agencies reporting only statewide figures were allocated to the counties in the state in proportion to each county's share of the state population. (2) No arrest data were provided for Florida, Illinois, Kansas, or Montana. Limited arrest statistics were provided for Kentucky, Mississippi, and South Dakota. For most counties in Vermont, the majority of arrest data were reported by the state police in that county. No offense data were provided for Montana. Limited offense data were available for Florida, Illinois, Kentucky, Mississippi, Missouri, South Dakota, and Tennessee. (3) UCR program staff at the Federal Bureau of Investigation (FBI) were consulted in developing the new adjustment procedures. However, these UCR county-level files are not official FBI UCR releases and are being provided for research purposes only. Users with questions regarding these UCR county-level data files can contact the National Archive of Criminal Justice Data at ICPSR. (4) The codebook is provided as a Portable Document Format (PDF) file. The PDF file format was developed by Adobe Systems Incorporated and can be accessed using PDF reader software, such as the Adobe Acrobat Reader. Information on how to obtain a copy of the Acrobat Reader is provided on the ICPSR Web site.

There were over 7.55 million arrests for all offenses in the United States in 2023. This figure is a decrease from 1990 levels, when the number of arrests was over 14.1 million. Arrest rate in the U.S. Along with the declining number of arrests, the arrest rate for all offenses in the United States has also decreased since 1990, from 5691.6 arrests per 100,000 of the population down to 2232.1 per 100,000 in 2023. Additionally, South Dakota had the highest arrest rate in the country in 2023 while Massachusetts had the lowest. High numbers of arrests and unsolved crimes A high number of arrests does not necessarily correlate to a high number of solved cases, and in the U.S., many cases remain unsolved. The crime clearance rate, or rate of closed cases, was less than half for violent crimes in the U.S., and less than 20 percent for property crimes.

In 2023, the arrest rate in South Dakota was 5,878.35 arrests per 100,000 inhabitants, the highest of any state. Kentucky, North Dakota, Arkansas, and Wyoming rounded out the top five states with the highest arrest rates in that year.

Alaska saw the highest rape rate in the United States in 2023, with 118.4 rapes per 100,000 inhabitants. The lowest rate was found in New Jersey, with 17.9 rapes per 100,000 inhabitants. Sexual assault in Alaska Fighting sexual assault in Alaska is particularly difficult due to small, isolated, close-knit communities who can be wary of airing their dirty laundry to outsiders, as well as a low number of law enforcement employees in the state. In addition, Alaska’s low population is spread out over a large land area, meaning that in the event of an assault being reported to police, it can take law enforcement hours, or even days, to reach the most isolated communities. The victims of sexual assault There tends to be more reported female victims of sexual assault than male victims. However, since sexual assault is typically an underreported crime, especially among males, these figures could be, and probably are, much higher. In addition, many victims of sexual offenses tend to be young, although sexual assault can occur at any age.
