The Great Depression was the great economic crisis that started after the U.S. stock market crash in 1929. The prices on the Wall Street stock market fell a lot from October 24 to October 29, 1929. Many people lost their jobs. By 1932, 25–30% of people lost their jobs. They became homeless and poor. This ended the wealth of the Roaring Twenties. Many people think that the Great Depression started on Tuesday, October 29, but economists think Black Tuesday was just one of the causes.
