The Chicago Crime Commission publication "The Gang Book 2012" gave the statistic that Chicago has more gang members than any other city in the United States: 150,000.[7] The city had 532 murders in 2012, however, it saw a decrease to 413 murders in 2013. Not all murders are gang-related, but the Chicago Police Department states that 80% of all shootings and murders in the city are gang-related, which means that most violence in the city is gang upon gang violence.
