Crime in the United States

Crime has been recorded in the United States since its founding and has fluctuated significantly over time, with a sharp rise after 1900 and reaching a broad bulging peak between the 1970s and early 1990s. After 1992, crime rates have generally trended downwards each year, with the exceptions of a slight increase in property crimes in 2001 and increases in violent crimes in 2005-2006, 2014-2016 and 2020-2021.^[1] While official federal crime data beginning in 2021 has a wide margin of error due to the incomplete adoption of the National Incident-Based Reporting System by government agencies, federal data for 2020-2021 and limited data from select U.S. cities collected by the nonpartisan Council on Criminal Justice showed significantly elevated rates of homicide and motor vehicle theft in 2020-2022.^[1][2][3] Although overall crime rates have fallen far below the peak of crime seen in the United States during the late 1980s and early 1990s,^[4][5] the homicide rate in the U.S. has remained high, relative to other "high income"/developed nations, with eight major U.S. cities ranked among the 50 cities with the highest homicide rate in the world in 2022. The aggregate cost of crime in the United States is significant, with an estimated value of $4.9 trillion reported in 2021.^[6] Data from the first half of 2023^[update], from government and private sector sources show that the murder rate has dropped, as much as 12% in as many as 90 cities across the United States.^[7] The drop in homicide rates is not uniform across the country however, with some cities such as Memphis, TN, showing an uptick in murder rates.^[7]

Statistics on specific crimes are indexed in the annual Uniform Crime Reports by the Federal Bureau of Investigation (FBI) and by annual National Crime Victimization Surveys by the Bureau of Justice Statistics. In addition to the primary Uniform Crime Report known as Crime in the United States, the FBI publishes annual reports on the status of law enforcement in the United States. The report's definitions of specific crimes are considered standard by many American law enforcement agencies. According to the FBI, index crime in the United States includes violent crime and property crime. Violent crime consists of five criminal offenses: murder and non-negligent manslaughter, rape, robbery, aggravated assault, and gang violence; property crime consists of burglary, larceny, motor vehicle theft, and arson.

The basic aspect of a crime considers the offender, the victim, type of crime, severity and level, and location. These are the basic questions asked by law enforcement when first investigating any situation. This information is formatted into a government record by a police arrest report, also known as an incident report. These forms lay out all the information needed to put the crime in the system and it provides a strong outline for further law enforcement agents to review. Society has a strong misconception about crime rates due to media aspects heightening their fear factor.^[8] The system's crime data fluctuates by crime depending on certain influencing social factors such as economics, the dark figure of crime, population, and geography.^[8]
