A leading U.S. counterterrorism, counterintelligence, and criminal investigative organization, the FBI has jurisdiction over violations of more than 200 categories of federal crimes.
The Uniform Crime Reporting (UCR) program compiles official data on crime in the United States, published by the Federal Bureau of Investigation (FBI).

The Violent Crime Control and Law Enforcement Act of 1994, commonly referred to as the 1994 Crime Bill, or the Clinton Crime Bill, is an Act of Congress dealing with crime and law enforcement; it became law in 1994. It is the largest crime bill in the history of the United States and consisted of 356 pages that provided for 100,000 new police officers, $9.7 billion in funding for prisons which were designed with significant input from experienced police officers. Sponsored by U.S. Representative Jack Brooks of Texas, the bill was passed by Congress and signed into law by President Bill Clinton. Then-Senator Joe Biden of Delaware drafted the Senate version of the legislation in cooperation with the National Association of Police Organizations, also incorporating the Assault Weapons ban and the Violence Against Women Act (VAWA) with Senator Orrin Hatch.
The National Crime Victimization Survey (NCVS), administered by the US Census Bureau under the Department of Commerce, is a national survey of approximately 49,000 to 150,000 households - with approximately 240,000 persons aged 12 or older - twice a year in the United States, on the frequency of crime victimization, as well as characteristics and consequences of victimization. The survey focuses on gathering information on the following crimes: assault, burglary, larceny, motor vehicle theft, rape, and robbery. The survey results are used for the purposes of building a crime index. It has been used in comparison with the Uniform Crime Reports and the National Incident-Based Reporting System to assess the dark figure of crime. The NCVS survey is comparable to the British Crime Survey conducted in the United Kingdom.
A violent crime, violent felony, crime of violence or crime of a violent nature is a crime in which an offender or perpetrator uses or threatens to use harmful force upon a victim. This entails both crimes in which the violent act is the objective, such as murder, assault, rape and assassination, as well as crimes in which violence is used as a method of coercion or show of force, such as robbery, extortion and terrorism. Violent crimes may, or may not, be committed with weapons. Depending on the jurisdiction, violent crimes may be regarded with varying severities from homicide to harassment.
A military prison is a prison operated by a military. Military prisons are used variously to house prisoners of war, unlawful combatants, those whose freedom is deemed a national security risk by the military or national authorities, and members of the military found guilty of a serious crime. There are two types: penal and confinement-oriented, where captured enemy combatants are confined for military reasons until hostilities cease. Most militaries have some sort of military police unit operating at the divisional level or below to perform many of the same functions as civilian police, from traffic-control to the arrest of violent offenders and the supervision of detainees and prisoners of war.
In the United States, the relationship between race and crime has been a topic of public controversy and scholarly debate for more than a century. Crime rates vary significantly between racial groups; however, academic research indicates that the over-representation of some racial minorities in the criminal justice system can in part be explained by socioeconomic factors, such as poverty, exposure to poor neighborhoods, poor access to public and early education, and exposure to harmful chemicals and pollution. Racial housing segregation has also been linked to racial disparities in crime rates, as black Americans have historically and to the present been prevented from moving into prosperous low-crime areas through actions of the government and private actors. Various explanations within criminology have been proposed for racial disparities in crime rates, including conflict theory, strain theory, general strain theory, social disorganization theory, macrostructural opportunity theory, social control theory, and subcultural theory.
National Incident-Based Reporting System (NIBRS) is an incident-based reporting system used by law enforcement agencies in the United States for collecting and reporting data on crimes. Local, state and federal agencies generate NIBRS data from their records management systems. Data is collected on every incident and arrest in the Group A offense category. These Group A offenses are 52 offenses grouped in 23 crime categories. Specific facts about these offenses are gathered and reported to NIBRS. In addition to the Group A offenses, 10 Group B offenses are reported with only the arrest information.

Crime has been recorded in the United States since its founding and has fluctuated significantly over time. Most available data underestimate crime before the 1930s, giving the false impression that crime was low in the early 1900s and had a sharp rise after. Instead, violent crime during the colonial period was likely three times higher than the highest modern rates in the data we have, and crime had been on the decline since colonial times. Within the better data for crime reporting and recording available starting in the 1930s, crime reached its broad, bulging modern 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. As of July 1, 2024 violent crime was down and homicides were on pace to drop to 2015 levels by the end of the year.
Property crime is a category of crime, usually involving private property, that includes, among other crimes, burglary, larceny, theft, motor vehicle theft, arson, shoplifting, and vandalism. Property crime is a crime to obtain money, property, or some other benefit. This may involve force, or the threat of force, in cases like robbery or extortion. Since these crimes are committed in order to enrich the perpetrator they are considered property crimes. Crimes against property are divided into two groups: destroyed property and stolen property. When property is destroyed, it could be called arson or vandalism. Examples of the act of stealing property is robbery or embezzlement.
America's Safest and Most Dangerous Cities is a publication issued annually by CQ Press, a division of Congressional Quarterly Inc., that ranks American cities on the basis of safety and crime. According to the publisher, the rankings are based upon statistics submitted by cities to the Federal Bureau of Investigation (FBI) which are then published by the FBI online, as part of the Bureau's Uniform Crime Reporting (UCR) program. Recently, the ranking has been criticized by several organizations, including The American Society of Criminology (ASC), Criminal Justice Journalists, and The United States Conference of Mayors as well as the FBI.
Quantitative methods provide the primary research methods for studying the distribution and causes of crime. Quantitative methods provide numerous ways to obtain data that are useful to many aspects of society. The use of quantitative methods such as survey research, field research, and evaluation research as well as others. The data can, and is often, used by criminologists and other social scientists in making causal statements about variables being researched.

Rape in the United States is defined by the United States Department of Justice as "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." While definitions and terminology of rape vary by jurisdiction in the United States, the FBI revised its definition to eliminate a requirement that the crime involve an element of force.
