HistoryA character grade: shown, never part of Calumet City’s overall grade.
Few Illinois towns list much on the Register (a typical Illinois town has 0.5 per 10,000 residents, the U.S. 2.4), so Calumet City’s 0.0 sits below most of its state (28% of Illinois towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to C. The pre-1940 share (±2.0 points) is firm at this size.

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.
The Calumet City post office opened in 1900, the earliest record of the town by name (U.S. post office records).
