Violent crime
According to reports in 2013, "most of Chicago's violent crime comes from gangs trying to maintain control of drug-selling territories", and is specifically related to the activities of the Sinaloa Cartel, which is active in several American cities. By 2006, the cartel sought to control most illicit drug sales. Violent crime rates vary significantly by area of the city, with more economically developed areas having low rates, but other sections have much higher rates of crime. In 2013, the violent crime rate was 910 per 100,000 people; the murder rate was 10.4 – while high crime districts saw 38.9, low crime districts saw 2.5 murders per 100,000.
