Answer:
Alabama
Step-by-step explanation:
The To Kill a Mockingbird novel takes place in Alabama, a Southern State of the U.S., more specifically it is set in a fictional place created by Lee: the Maycomb County. Scout, the narrator, tells us a bit about the latter in the following lines of chapter one:
Maycomb was an old town, but it was a tired old town when I first knew it.
And she tells us a bit more about Alabama in Chapter 7:
There are no clearly defined seasons in South Alabama; summer drifts into autumn, and autumn is sometimes never followed by winter but turns to a days-old spring that melts into summer again. That fall was a long one, hardly cool enough for a light jacket. Jem and I were trotting in our orbit one mild October afternoon when our knot-hole stopped us again. Something white was inside this time.
