Final answer:
During the Great Economic Depression, approximately 15.5 million American workers were unemployed by the end of 1933. This accounted for one-fourth of the American workforce at that time. The impact of the depression was severe in cities, leading to the emergence of shantytowns known as "Hoovervilles" as many Americans faced unemployment and homelessness.
Step-by-step explanation:
The Great Economic Depression, which lasted from 1929 to 1939, resulted in a significant increase in unemployment in the United States. By the end of the Great Depression, it is estimated that there were approximately fifteen and a half million unemployed American workers in 1933. This accounted for one-fourth, or 25%, of the American workforce at that time.
The impact of the depression was particularly severe in cities, where many Americans were unable to provide for themselves and their families. Shantytowns called "Hoovervilles" emerged on the outskirts of cities, housing individuals and families who were suffering from unemployment and homelessness. The unemployment rate reached its peak of 25% during the Great Depression, causing immense hardship and economic uncertainty for millions of Americans.
