While the books don't explicitly name a city or state, there are clues suggesting it's set in a typical American suburban town:
* The school and surrounding community seem familiar to the typical American experience. This is reinforced by the characters' clothing, activities, and overall lifestyle.
* The books often reference pop culture and trends that are relevant to a wider American audience. This helps place the story in a relatable context for young readers.
While the exact setting is unspecified, the focus of the Dear Dumb Diary series is on the universal experiences of being a middle school student, making the setting less important than the relatable characters and humorous situations.
