What is the main setting of "The Great Gatsby"?

The main setting of "The Great Gatsby" is Long Island, which plays a crucial role in the novel. The story is divided between the affluent neighborhoods of West Egg and East Egg on Long Island, where the wealthy characters, including Jay Gatsby and Tom Buchanan, live. The geographic and social distinctions between these two areas reflect the novel's themes of class, aspiration, and the American Dream. While New York City is significant in the story, particularly for its representation of modernity and excess, the core narrative revolves around the residences and parties that take place in Long Island's elite circles, making it the central locale of Fitzgerald's exploration of 1920s American society.
