What you'll learn
The U.S. economy has had great times and very hard times. A boom is a period of fast growth. A bust is a sharp drop. In this lesson you will learn six big events the GED expects you to know:
- the Industrial Revolution in the United States (1800s to early 1900s),
- the Great Depression (1929–1941),
- the New Deal (1933–late 1930s),
- the post–World War II boom (late 1940s–1960s),
- stagflation in the 1970s, and
- the 2008 financial crisis and Great Recession.
How the GED tests this: You will rarely need to recall a date by itself. Instead, you will read a short source. It might be:
- a line graph of unemployment,
- a table of inflation rates,
- a passage from a presidential speech, or
- a short history article.
Then you answer questions about it. Typical questions ask you to:
- read a graph,
- find a trend,
- connect a cause to its effect, or
- compare two sources.
Economics questions make up roughly 15% of the Social Studies test. Economic history also shows up in U.S. history questions.
Key terms
- Industrial Revolution — the shift from hand tools and farms to machines and factories (textile mills, steel mills).
- urbanization — people moving from the countryside into cities (farm families moving to Chicago for factory jobs).
- depression — a very long, very deep downturn in the economy (the 1930s).
- recession — a significant, widespread decline in economic activity lasting more than a few months (2007–2009).
- unemployment rate — the percent of people who want a job and are looking but cannot find one (24.9% in 1933).
- stock market crash — a sudden, steep fall in stock prices (October 1929).
- bank run — many depositors rushing to withdraw cash at once because they fear the bank will fail.
- New Deal — President Franklin D. Roosevelt's programs to bring relief, recovery, and reform (CCC, Social Security, FDIC).
- deposit insurance — a government guarantee that savers get their money back if an insured bank fails (the FDIC, 1933).
- inflation — a general rise in prices over time (a gallon of milk costing more each year).
- stagflation — high inflation and high unemployment (a *stag*nant economy) at the same time (the 1970s).
- embargo — an official ban on trade with a country (the 1973 OPEC oil embargo).
- subprime mortgage — a home loan to a borrower with weak credit, usually at a higher interest rate.
- stimulus — government spending or tax cuts meant to boost a weak economy (the 2009 Recovery Act).
The Industrial Revolution and the postwar boom
In plain words: Machines moved work from farms and homes into factories and cities.
Industrial Revolution (about 1800–1920). Picture a family spinning thread by hand at home. Now picture a mill where one water wheel runs rows of spinning machines. That change is the heart of the Industrial Revolution — the shift from hand tools and farms to machines and factories. Early textile mills in New England used water power to spin cotton into cloth. After the Civil War, industry grew much faster. Key drivers:
- Railroads. The first transcontinental railroad (1869) linked the East and West coasts. Now factories could sell to buyers across the whole nation.
- New technology. Steel made by the Bessemer process changed building. So did electricity and the telephone. Later came the assembly line (Henry Ford, 1913). All of these made goods cheaper.
- Workers. Farm machines (reapers, steel plows, tractors) meant farms needed fewer hands. Millions of rural Americans moved to cities. Millions of immigrants came too.
- Big business. Giant firms such as Standard Oil grew powerful. Working conditions were harsh, and this led workers to form labor unions.
Example: In 1840, about 69% of U.S. workers farmed. By 1900, it was about 41%. By 2000, it was about 2%. A graph of this drop is classic GED material.
Post–World War II boom (late 1940s–1960s). In plain words: after the war, Americans had jobs, money, and things they wanted to buy.
World War II production ended the Depression. After the war, several forces created two decades of strong growth:
- pent-up demand — people were ready to buy things they could not get during the war;
- the GI Bill, which paid for veterans' education and home loans;
- new homes built in the suburbs;
- the interstate highway system (1956);
- cheap energy.
Family incomes rose. A large middle class bought houses, cars, and televisions.
The Great Depression and the New Deal
In plain words: The Depression was the worst economic collapse in U.S. history. Many problems hit at the same time.
Causes of the Great Depression. No single cause explains it. Think of a table that falls because several legs break at once. The GED expects you to know several causes:
- Stock speculation. In the 1920s, many people bought stocks "on margin" — with borrowed money. Prices crashed in October 1929. Then these buyers could not repay their loans.
- Bank failures. About 9,000 banks failed from 1930 to 1933. There was no deposit insurance, so savers lost everything. Fear spread, and bank runs spread with it.
- Falling demand. Families without jobs stopped buying. So factories cut more jobs. Then even fewer people could buy. This is a downward spiral.
- A shrinking money supply. The Federal Reserve let the money supply fall by about a third.
- Trade collapse. The Smoot-Hawley Tariff (1930) raised taxes on imports. Other countries struck back, and world trade shrank.
- Farm crisis. Crop prices were already low in the 1920s. Then the Dust Bowl drought hit the Plains in the 1930s.
Example: Unemployment rose from 3.2% in 1929 to 24.9% in 1933. That is about 1 in 4 workers without a job.
The New Deal (1933–1939): the three R's. In plain words: President Franklin D. Roosevelt's government tried to help people now, fix the economy, and stop a repeat.
| Goal | Program | What it did |
|---|---|---|
| Relief (help now) | Civilian Conservation Corps (CCC), Works Progress Administration (WPA) | Government hired the unemployed for forests, parks, roads, schools |
| Recovery (fix the economy) | Agricultural Adjustment Act (AAA), Tennessee Valley Authority (TVA) | Raised farm prices; built dams and brought electricity to a poor region |
| Reform (prevent a repeat) | FDIC, Securities and Exchange Commission (SEC), Social Security Act (1935) | Insured deposits; policed the stock market; pensions and unemployment insurance |
Unemployment fell from 1933 to 1937. But it jumped again in 1938, after the government cut spending and the Federal Reserve tightened credit. Only the huge military buildup of World War II brought unemployment down to very low levels. The New Deal made the federal government's role in the economy permanently bigger.
Stagflation in the 1970s
In plain words: Stagflation means prices rise fast while jobs disappear. Two bad things happen at once.
Usually, inflation and unemployment move in opposite directions:
- In a boom, jobs are easy to find, but prices rise faster.
- In a slump, more people lose jobs, but prices rise more slowly.
Think of a busy restaurant. When crowds come in, it hires more cooks and can raise menu prices. When the crowds stop, it cuts staff and holds prices down. The 1970s broke this pattern. Prices and unemployment were both high.
Causes:
- Oil shocks. In October 1973, Arab members of OPEC placed an oil embargo (a ban on trade) on the United States. They did this because the U.S. supported Israel in the Yom Kippur War. Oil prices roughly quadrupled — they became about four times higher. A second shock followed the 1979 Iranian Revolution. Higher energy costs raised the price of almost everything. They also forced businesses to cut workers.
- Earlier spending on the Vietnam War and social programs had already pushed prices up.
Example: From 1973 to 1975, inflation rose from 6.2% to 9.1%. Unemployment rose from 4.9% to 8.5%. Both went up at once. By 1980, inflation reached 13.5%.
The cure. Fed Chair Paul Volcker raised interest rates sharply around 1979–1981. Higher rates made loans cost more, so people and businesses spent less. Inflation fell. But the cost was a deep recession in 1981–1982, when unemployment rose above 10%.
The 2008 financial crisis
In plain words: Risky home loans went bad. Banks lost huge sums, and the whole economy slid into a deep recession.
Causes.
- In the 2000s, home prices climbed fast.
- Lenders gave subprime mortgages — home loans to borrowers with weak credit. Many had low "teaser" rates that later jumped. When the rate jumped, the monthly payment jumped too.
- Banks bundled many mortgages together into securities (investments that can be bought and sold). They sold them around the world. Many firms borrowed heavily to buy them.
- Home prices fell in 2006–2007. Many borrowers defaulted — they stopped paying their loans.
- The securities collapsed in value. Banks that held them faced huge losses.
- In September 2008, Lehman Brothers went bankrupt, and lending froze.
Effects. The Great Recession lasted from December 2007 to June 2009. It was the worst downturn since the 1930s. Unemployment peaked at 10.0% in October 2009. Millions of families lost homes to foreclosure — the lender taking back a home when the loan is not paid.
Responses:
- TARP (October 2008): up to $700 billion to stabilize banks and automakers.
- Federal Reserve: cut its key interest rate to nearly zero and bought bonds.
- American Recovery and Reinvestment Act (2009): a stimulus of roughly $800 billion.
- Dodd-Frank Act (2010): tighter rules on large banks. It also created a consumer financial protection agency.
Comparison: Leaders had learned from the 1930s, so they acted quickly. Deposit insurance helped prevent runs by ordinary savers. Unemployment peaked far below the Depression's 24.9%.
Calculations you may need
\text{percent change} = \dfrac{\text{new value} - \text{old value}}{\text{old value}} \times 100- A positive result is an increase. A negative result is a decrease.
- Always divide by the old (starting) value.
Percentage points vs. percent change. Say unemployment goes from 4.9% to 8.5%.
- It rose 8.5 - 4.9 = 3.6 percentage points. This is simple subtraction.
- The percent change is \dfrac{3.6}{4.9} \times 100 \approx 73\%.
Read the question to see which one it wants.
Defined formulas. The GED sometimes gives you a formula in the question. One example is the "misery index" = inflation rate + unemployment rate. Just use it exactly as written.
Example 1: Reading a line graph
Source: a line graph of U.S. unemployment shows 3.2% (1929), 8.7% (1930), 15.9% (1931), 23.6% (1932), 24.9% (1933).
Question: By how many percentage points did unemployment rise from 1929 to 1933?
Think-aloud:
- "Percentage points" means simple subtraction—no dividing.
- Read the two values: 1929 = 3.2, 1933 = 24.9.
- 24.9 - 3.2 = 21.7 percentage points.
- Elimination: "about 678%" is the percent change—a different question. 28.1 comes from adding instead of subtracting.
Answer: 21.7 percentage points.
Example 2: Matching a source to a program
Source: "Our greatest primary task is to put people to work. … It can be accomplished in part by direct recruiting by the Government itself …" — Franklin D. Roosevelt, First Inaugural Address, 1933
Question: Which program reflects this idea? (A) FDIC (B) Works Progress Administration (C) Social Security (D) Sherman Antitrust Act
Think-aloud:
- Key features: put people to work + the Government itself hires them.
- The WPA directly employed millions of people to build roads, schools, and bridges. ✔
- FDIC insured bank deposits (reform, not jobs). Social Security pays pensions (income, not jobs). The Sherman Act (1890) is from the Industrial era and targets monopolies.
Answer: (B) the Works Progress Administration.
Example 3: Cause and effect with two data series
Source: a table shows inflation of 3.2% in 1972, 6.2% in 1973, and 11.0% in 1974. A note says the OPEC oil embargo began in October 1973 and oil prices roughly quadrupled.
Question: Which conclusion is best supported?
Think-aloud:
- Look at the timing: inflation was already rising in 1973 but nearly doubled again in 1974, right after the embargo.
- Link the cause: oil is used to make and ship almost everything, so a big jump in oil prices raises many other prices.
- Reject overstatements: "The embargo was the only cause of 1970s inflation" is too absolute—inflation was rising before October 1973. "Inflation fell after the embargo" contradicts the data.
Answer: The sharp rise in oil prices after the 1973 embargo likely contributed to the jump in inflation in 1974.
Example 4: Comparing two crises
Source A: Unemployment peaked at 24.9% in 1933. About 9,000 banks failed from 1930 to 1933. Source B: Unemployment peaked at 10.0% in October 2009. Deposit insurance, created in 1933, protected savers.
Question: Which statement does the evidence from both sources support?
Think-aloud:
- Put facts side by side: 24.9% vs. 10.0%; thousands of bank failures with no insurance vs. insured deposits.
- A reasonable connection: a reform created during the first crisis (deposit insurance) helped limit damage in the second.
- Eliminate: "The two crises caused equal unemployment" (24.9 ≠ 10.0) and "Banks did not fail in either crisis" (Source A contradicts).
Answer: A reform from the Great Depression helped protect savers during the 2008 crisis, when unemployment peaked much lower.
Common traps
- Points vs. percent. Wrong: "Unemployment went from 4.9% to 8.5%, a 3.6% increase." Right: it rose 3.6 percentage points, which is a 73% increase.
- Mixing up time periods. Wrong: "Deposit insurance was a response to the 2008 crisis." Right: the FDIC was created in 1933, during the New Deal.
- Confusing the New Deal programs. Wrong: "Social Security put people to work." Right: CCC and WPA created jobs; Social Security gave pensions and unemployment insurance; FDIC and SEC were reforms.
- Reversing cause and effect. Wrong: "People moved to cities, so farmers bought tractors." Right: machines reduced the need for farm workers, so people moved to cities for factory jobs.
- Assuming inflation and unemployment always move in opposite directions. Wrong: "High unemployment means low inflation." Right: in the 1970s (stagflation) both were high.
- Single-cause thinking. Wrong: "The 1929 crash alone caused the Depression." Right: bank failures, falling demand, a shrinking money supply, tariffs, and the farm crisis all contributed.
GED strategy for economic history
- Read the question first, then the source. Know whether you are hunting for a number, a trend, a cause, or a purpose.
- Check the graph's title, axes, units, and legend before reading values. Is it percent or millions? Which line is which?
- Use the source's date and context. An introduction like "March 1933, when banks were failing" is a clue to the author's purpose.
- Watch absolute words—always, never, every, only. One counterexample in the data makes the choice wrong.
- Match all features. When linking a quote to a program, choose the one that fits every key idea, not just one.
- Two-source questions: jot one fact from each source side by side before reading the choices.
- Time: data questions are quick points—aim for about 1 to 1½ minutes each and flag anything that takes longer.

Unemployment During the Great Depression
The graph shows the estimated percentage of the U.S. labor force that was unemployed each year from 1929 to 1941. The stock market crashed in October 1929. President Franklin D. Roosevelt took office in March 1933 and began the New Deal.
Source: estimates based on historical U.S. Bureau of Labor Statistics data.
Based on the graph, in which year was the unemployment rate the highest?
Hint
Find the highest point on the line, then read straight down to the year.
Step-by-step solution
Where the answer comes from: the highest point on the line is labeled 24.9, above the year '33 (1933).
Step by step:
- Scan the line for its tallest point. The values climb from 3.2 (1929) to 23.6 (1932) and then to 24.9 in 1933.
- After 1933 the line goes down: 21.7 in 1934, 20.1 in 1935.
- Check the other choices: 1929 was the lowest point (3.2), 1938 was a smaller second rise (19.0), and 1941 was 9.9.
So the unemployment rate peaked in 1933, the worst year of the Great Depression—about one in four workers had no job.
Tip: for "highest/lowest" questions, compare the actual data labels rather than eyeballing. Two points can look close (23.6 and 24.9 here).

Unemployment During the Great Depression
The graph shows the estimated percentage of the U.S. labor force that was unemployed each year from 1929 to 1941. The stock market crashed in October 1929. President Franklin D. Roosevelt took office in March 1933 and began the New Deal.
Source: estimates based on historical U.S. Bureau of Labor Statistics data.
Which statement is supported by the information in the graph?
Hint
Test each choice against the actual numbers. Watch for words like every and never.
Step-by-step solution
Where the answer comes from: the graph's labels for 1933–1938 are 24.9, 21.7, 20.1, 16.9, 14.3, and then 19.0 in 1938.
Step by step:
- From 1933 to 1937 each value is lower than the one before (24.9 → 21.7 → 20.1 → 16.9 → 14.3). So unemployment fell every year in that span.
- In 1938 the value jumps to 19.0—a rise. (Historians call this the "Roosevelt recession," which followed cuts in federal spending.)
- The other choices fail: unemployment did not return to 1929 levels by 1941 (9.9 vs. 3.2); it rose every year from 1929 to 1933 but mostly fell after the New Deal began; and it was above 20% in 1932, 1933, 1934, and 1935.
Answer: Unemployment fell each year from 1933 to 1937, then rose in 1938.
Tip: "Supported by the graph" means every part of the statement must match the data. One false part makes the whole choice wrong.
Summary
- The Industrial Revolution (1800s) moved Americans from farms to factories and cities. Railroads, steel, new machines, and immigration powered it.
- The Great Depression (1929–1941) had many causes: speculation, bank failures, falling demand, a shrinking money supply, and tariffs. Unemployment peaked near 25% in 1933.
- The New Deal offered relief (CCC, WPA), recovery (AAA, TVA), and reform (FDIC, SEC, Social Security).
- The post–WWII boom brought suburbs, cars, and a growing middle class. The 1970s brought stagflation after the oil shocks.
- The 2008 crisis began with risky mortgages. Responses included TARP, near-zero interest rates, and a stimulus; unemployment peaked far below Depression levels.
- On the GED, read values carefully. Keep percentage points separate from percent change. Let the source supply the evidence.
