Answer:
A period of great economic depression worldwide between 1929 and 1939[1] became evident after a major fall in stock prices in the United States.[2] The economic contagion began around September and led to the Wall Street stock market crash of October 24 (Black Thursday). The economic shock impacted most countries across the world to varying degrees. It was the longest, deepest, and most widespread depression of the 20th century.[3]
Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession.[4] Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II.[5] Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% and in some countries rose as high as 33%.[6]
Cities around the world were hit hard, especially those dependent on heavy industry. Construction was virtually halted in many countries. Farming communities and rural areas suffered as crop prices fell by about 60%.[7][8][9] Faced with plummeting demand and few job alternatives, areas dependent on primary sector industries suffered the most.[10]
