Crime in Canada is generally considered low overall. Under the Canadian constitution, the power to establish criminal law and rules of investigation is vested in the federal Parliament. The provinces share responsibility for law enforcement, and while the power to prosecute criminal offences is assigned to the federal government, responsibility for prosecutions is delegated to the provinces for most types of criminal offences. Laws and sentencing guidelines are uniform throughout the country, but provinces vary in their level of enforcement.
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 blacks 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 in St. Louis includes an overview of crime both in the city of St. Louis and in the Greater St. Louis metropolitan area. Crime in the city increased from the 1960s through the early 1990s as measured by the index crime rate, followed by a decline in crime rates through 2014. Despite decreasing crime, rates of violent crime and property crime in both the city and the metropolitan area remain higher than the national metropolitan area average. In addition, the city of St. Louis consistently has been ranked among the most dangerous cities in the United States. As of April 2017, St. Louis has the highest murder rate in America. At the end of 2017, St. Louis metropolitan had 205 murders, 159 of which were within the city limits.

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. 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. Although overall crime rates have fallen far below the peak of crime seen in the United States during the late 1980s and early 1990s, 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. Data from the first half of 2023, 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. 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.
