Offset lithograph thematic map printed in red and black, 648 x 445 mm (small split to a single fold); folding into original envelope.

Issued to accompany sociologist Frederic Thrasher's seminal 1927 study, The Gang: A Study of 1,313 Gangs in Chicago (seen here), the map depicts the locations of youth gangs in the "poverty belt," rather than focusing on Capone's Mob. Thrasher applied thematic mapping to depict organized criminal activity to help support his thesis that such activity thrives in urban spaces. His concern was that second-generation immigrant children evolved from “play groups” and into youth gangs. His central conclusion was the identification of a place called “Gangland” … “a geographically and socially interstitial area of the city”. Numerous notations printed in red provide added detail of gang territories that include “Hobohemia” in the Gold Coast, “Jewish-Polish Frontier” in Douglas Park, and “Slave Town” in what is now Randolph Street Market.
