Prior to the 1930s, only sporadic information is available regarding crime in the city and region. As early as 1894, there were 80 homicides in the city, according to the
St. Louis Post-Dispatch. For the period 1901 to 1910, the city recorded 804 homicides, with a homicide rate for the period of 12 per 100,000 residents. In 1915, the city police reported 74 homicides, while 103 people were recorded as having died of homicide by the medical examiner. In 1921, there were 138 homicides in St. Louis according to the St. Louis city coroner, giving a rate of about 14 per 100,000 residents. After 1934, St. Louis reported crime statistics to the FBI, which compiled and published reports of
index crime and homicides in the annual
Uniform Crime Reports. Starting in the 1950s, the city of St. Louis saw increases in its index crime and homicide rates, which both peaked in the early 1990s. However, St. Louis saw its peak number of index crimes and homicides in 1969 and 1970, respectively. Although some of the reduction in the number of index crimes since the early 1990s can be attributed to St. Louis's loss of population, other factors include low inflation, the decline of open-air drug markets, and a decline in crack cocaine use. In 2009, 67 police departments in St. Louis County reported 33,718 index crimes, and three departments did not report crime to the FBI (these include the departments of Wellston, Normandy, and Lakeshire). In 2010, the
St. Louis Metropolitan Police Department (the city police department) reported 33,782 index crimes, which was the lowest total reported index crimes since 1967 (however, index crimes in 1967 did not include larceny under $50, arson, or non-negligent manslaughter). The index crime rate fell 9.2 percent from 2009, with a 15.6 percent decline in violent crime and a 7.6 percent decline in property crime. However,
Chief of Police Daniel Isom noted in the report that both homicides and burglaries remain problems in the city. For 1958–1959, UCR data specified that Greater St. Louis included St. Louis, St. Charles, and Jefferson counties in Missouri, and Madison and St. Clair counties in Illinois. ==2011 and 2012==
