Question: What percentage did the Dow Jones fall in the historical era where the book takes place?

Knowledge 1: To Kill a Mockingbird
The story takes place during three years (1933–35) of the Great Depression in the fictional "tired old town" of Maycomb, Alabama, the seat of Maycomb County. It focuses on six-year-old Jean Louise Finch (Scout), who lives with her older brother, Jem, and their widowed father, Atticus, a middle-aged lawyer. Jem and Scout befriend a boy named Dill, who visits Maycomb to stay with his aunt each summer. The three children are terrified of, and fascinated by, their neighbor, the reclusive Arthur "Boo" Radley. The adults of Maycomb are hesitant to talk about Boo, and, for many years few have seen him. The children feed one another's imagination with rumors about his appearance and reasons for remaining hidden, and they fantasize about how to get him out of his house. After two summers of friendship with Dill, Scout and Jem find that someone leaves them small gifts in a tree outside the Radley place. Several times the mysterious Boo makes gestures of affection to the children, but, to their disappointment, he never appears in person. [SEP] Knowledge 2: Tanzania
Market strategist Phil Dow believes distinctions exist "between the current market malaise" and the Great Depression. He says the Dow Jones average's fall of more than 50% over a period of 17 months is similar to a 54.7% fall in the Great Depression, followed by a total drop of 89% over the following 16 months. "It's very troubling if you have a mirror image," said Dow. Floyd Norris, the chief financial correspondent of The New York Times, wrote in a blog entry in March 2009 that the decline has not been a mirror image of the Great Depression, explaining that although the decline amounts were nearly the same at the time, the rates of decline had started much faster in 2007, and that the past year had only ranked eighth among the worst recorded years of percentage drops in the Dow. The past two years ranked third, however.

In finance, Black Monday refers to Monday, October 19, 1987, when stock markets around the world crashed. The crash began in Hong Kong and spread west to Europe, hitting the United States after other markets had already declined by a lot. The Dow Jones Industrial Average (DJIA) fell exactly 508 points to 1,738.74 (22.61%). In Australia and New Zealand, the 1987 crash is also referred to as ``Black Tuesday ''because of the time zone difference.
