How old is Scout Finch in To Kill a Mockingbird?
Scout begins the story when she is five (almost six) years old and concludes the story when she is eight.
Scout narrates the story in retrospect and mentions that enough time has passed for her and Jem to be able to look back at the events leading up to how he broke his arm when he was nearly thirteen years old. Scout mentions that she is almost six years old and Jem is nearly ten when the story begins. As the story progresses, Scout experiences many eye-opening events, which includes the wrongful conviction of Tom Robinson. By the end of the story, Scout is almost nine years old. In chapter 23, Scout begins to argue with her aunt, and Jem says,
"Aun-ty...she ain’t nine yet" (Lee, 228).
A few chapters later, Jem and Scout get attacked by Bob Ewell while they are walking home from the Halloween festival, and Jem breaks his arm. Fortunately, Boo Radley saves their lives, and Scout gets an opportunity to talk to her reclusive neighbor for the first time. While standing on Boo's porch, Scout depicts her maturity by viewing the neighborhood from Boo's perspective.
To Kill a Mockingbird is told from the perspective of Jean Louise (Scout) Finch as an adult looking back at the events that occurred during her childhood.
In chapter one, however, she shares how old she was when the chain of events began to occur, which coincides with the time that little Dill came to the house. She was almost six years old when the events began to unfold.
When I was almost six and Jem was nearly ten, our summertime boundaries (within calling distance of Calpurnia) were Mrs. Henry Lafayette Dubose's house two doors to the north of us, and the Radley Place three doors to the south. (Chapter 1)
By the end of chapter thirty, Scout is eight years old, but has certainly grown much more psychologically and intellectually over the course of the novel. With Ewell's death, the drama and chaos that came over the once-peaceful town end.
