What this topic is asking
The Roaring Twenties ended in the worst economic collapse in American history. Standard 4 (Becoming a World Power through World War II) wants you to analyze the causes of the Great Depression, the stock market crash, overproduction, credit, and bank failures, and its effects on ordinary people, including mass unemployment and the Dust Bowl, plus the failure of President Hoover's response. LEAP often uses an unemployment graph, a breadline photograph, or a Dust Bowl image as the source.
The stock market crash
The most visible trigger was the collapse of the stock market.
The deeper causes
The exam expects you to look past the crash to the underlying causes that had built up during the decade:
- Overproduction and underconsumption. Factories and farms produced more goods than Americans could afford to buy, partly because wages had not kept pace with output. When goods went unsold, production and jobs were cut.
- Excessive credit and speculation. Consumers piled up debt on installment buying, and investors gambled on the stock market with borrowed money. When the bubble burst, debts could not be repaid.
- Unequal distribution of wealth. Too much income went to the wealthy few and too little to ordinary workers and farmers, so demand was weak and fragile.
- A weak banking system. Many banks were small and undercapitalized, vulnerable to panics and runs.
Bank failures and unemployment
When the crisis hit, the banking system collapsed. As banks failed, depositors lost their savings, which destroyed spending power and confidence; frightened people pulled money out of surviving banks, causing more to fail; and banks that survived stopped lending, starving businesses of credit. The result was a downward spiral: businesses closed, and unemployment climbed to roughly 25 percent by 1933. Breadlines, soup kitchens, and shantytowns called "Hoovervilles" spread across the country.
The Dust Bowl
Nature compounded the disaster. A severe drought in the early 1930s, worsened by years of poor farming practices that had stripped the soil, turned the southern Great Plains into the Dust Bowl. Enormous dust storms buried farms, ruined crops, and forced hundreds of thousands of families (often called "Okies") to abandon their land and migrate west, especially to California, in search of work. The Dust Bowl is a vivid LEAP example of how the Depression combined economic and environmental catastrophe.
Hoover's response
President Herbert Hoover faced the collapse with a philosophy that the federal government should not intervene heavily in the economy. He believed recovery should come through business confidence and voluntary local and charitable action, and he feared that direct relief would weaken self-reliance. He did eventually take some steps, but they were too limited and too late, and his name became attached to the misery ("Hoovervilles"). His perceived failure to act boldly led voters to elect Franklin D. Roosevelt in 1932 (see the New Deal).

A single-select item assessing analysis of a data source (Standard 4; Standard 1 source analysis).
Correct answer: the onset of the Great Depression, the worst economic collapse in American history.
After the 1929 stock market crash, businesses failed, banks closed, and roughly one in four workers lost their jobs by 1933. Distractors such as "a wartime economic boom" describe the opposite condition, and "the prosperity of the 1920s" predates the collapse shown in the graph.
LA LEAP 2025 US History (style)2 marksPart A: Identify two causes of the Great Depression. Part B: Explain why bank failures made the Depression worse.Show worked answer →
A two-part evidence-based item (Standard 4; Standard 1 claims and evidence).
Part A (1 point): any two of the stock market crash of 1929, overproduction and underconsumption, excessive use of credit and stock speculation, bank failures, and an unequal distribution of wealth.
Part B (1 point): bank failures made the Depression worse because when banks collapsed, people lost their savings, which destroyed spending power and confidence, and surviving banks stopped lending, deepening the downturn. A distractor saying bank failures helped the economy recover is the opposite of the truth.
Markers reward naming two causes in Part A and explaining the loss of savings and lending in Part B.
