Calumet City ( KAL-yuu-MET) is a city in Cook County, Illinois, United States. The population was 36,033 at the 2020 census. It is part of the Chicago metropolitan area.
History
Calumet City (commonly referred to locally as "Cal City") was founded in 1893 when the villages of Schrumville and Sobieski Park merged under the name of West Hammond, since it lies on the west side of the Illinois-Indiana line from Hammond, Indiana.
In 1916, when alcohol was prohibited in Indiana, West Hammond became a preferred location for drinkers coming from northwest Indiana. Bootleggers including Al Capone built on this basis once the Prohibition era arrived, and West Hammond gained the nickname of "Sin City".

West Hammond became known for illegal alcohol consumption, gambling, and prostitution. In 1923, residents wishing to rid the city of its reputation voted to change the name from West Hammond to Calumet City.
Frank LaPorte is believed to have been the member of the Chicago Outfit who was most responsible for developing and maintaining the "Sin Strip" area of Calumet City. Police avoided Sin Strip and risked violence if they tried to make an arrest.
In 1959, the state of Illinois conducted a police raid that resulted in 98 arrests and the seizure of business records. An article published in Chicago Daily News on June 2, 1959, exposed LaPorte as being instrumental in the illegal activities in Calumet City.

In 1995, the city began demolishing bars and taverns in the "Sin Strip" area.
