What is the setting in the book Fahrenheit 451?

I looked it up on the computer and it says chicago and st louis

Fahrenheit 451 is set in a suburban city in the twenty first century. The main character, Montag, lives in a dark empty house just like everyone else. The other people in the story are all constantly surrounded by technology, which is a surprisingly accurate description when compared with what our own lives consist of, considering the story was written almost fifty years ago. The atmosphere of the story is very heavy throughout. For most of the book, Montag, the main character, is either scared, confused or angry, and seeing the world through his eyes allows the reader to experience this same atmosphere.
