Why is To Kill a Mockingbird set during the Great Depression?Quotes implying that they're actually in the Great Depression.

Author Harper Lee (born in
1926) based much of her first and only novel, To Kill a
Mockingbird, on her own life experiences. The character of Scout is based on
Miss Lee, who was also a tomboy and was about the same age as Scout during the years
(1933-1935) encompassing the novel. Miss Lee grew up in little Monroeville, Alabama, and
it was the model for Maycomb. Her father was an attorney, like Atticus; and her best
friend was Monroeville summer resident, future writer Truman Capote, who was portrayed
by Dill in the novel. The Great Depression was still ongoing during these years, and
since it was a worldwide crisis, it was an essential part of life for both Miss Lee and
her characters in the novel.
