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.
Timeline of six big events in U.S. economic history from 1800 to 2020. Bars show the Industrial Revolution (about 1800 to 1920), the Great Depression (1929 to 1941), the New Deal (1933 to 1939), the post–World War II boom (late 1940s to 1960s), stagflation in the 1970s, and the Great Recession (December 2007 to June 2009). Booms are blue, busts are red, the New Deal response is green. Booms and busts in U.S. economic history 1800 1840 1880 1920 1960 2000 Industrial Revolution about 1800–1920 Great Depression 1929–1941 New Deal 1933–1939 Post–WWII boom late 1940s–1960s Stagflation 1970s (into early 1980s) Great Recession Dec. 2007–June 2009 Growth / boom Bust Government response

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.

Words to know

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).

All Social Studies words in the glossary

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.

The bars shrink sharply, showing workers moving from farms to factories and cities. Share of U.S. workers who farmed 0% 20% 40% 60% 80% Percent of all workers about 69% 1840 about 41% 1900 about 2% 2000

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:

  1. 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.
  2. 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.
  3. Falling demand. Families without jobs stopped buying. So factories cut more jobs. Then even fewer people could buy. This is a downward spiral.
  4. A shrinking money supply. The Federal Reserve let the money supply fall by about a third.
  5. Trade collapse. The Smoot-Hawley Tariff (1930) raised taxes on imports. Other countries struck back, and world trade shrank.
  6. Farm crisis. Crop prices were already low in the 1920s. Then the Dust Bowl drought hit the Plains in the 1930s.
Cycle diagram of the Great Depression downward spiral. Families lose jobs, so families stop buying, so factory sales fall, so factories cut more jobs, which leads back to more families losing jobs. Each trip around the loop makes the economy smaller. The downward spiral of falling demand Workers lose jobs Families stop buying Factory sales fall Factories cut more jobs Each loop shrinks the economy

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.

GoalProgramWhat 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
Diagram of the New Deal three Rs. Relief, meaning help now: CCC and WPA hired the unemployed. Recovery, meaning fix the economy: AAA raised farm prices and TVA built dams and brought electricity. Reform, meaning prevent a repeat: FDIC insured deposits, SEC policed the stock market, and Social Security gave pensions and unemployment insurance. The New Deal: the three R's (1933–1939) Relief help now CCC WPA Hired the unemployed for parks, roads, schools Recovery fix the economy AAA TVA Raised farm prices; dams and electricity Reform prevent a repeat FDIC, SEC Social Security (1935) Insured deposits; stock rules; pensions

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%.

Grouped bar graph comparing 1973 and 1975. Inflation rose from 6.2 percent to 9.1 percent. Unemployment rose from 4.9 percent to 8.5 percent. Both rose at the same time, which is stagflation. Stagflation: both rates rose at once 0% 2% 4% 6% 8% 10% Percent 6.2% 4.9% 1973 9.1% 8.5% 1975 Inflation Unemployment

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.

  1. In the 2000s, home prices climbed fast.
  2. 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.
  3. 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.
  4. Home prices fell in 2006–2007. Many borrowers defaulted — they stopped paying their loans.
  5. The securities collapsed in value. Banks that held them faced huge losses.
  6. In September 2008, Lehman Brothers went bankrupt, and lending froze.
Flowchart of the causes of the 2008 financial crisis in six steps: 1, home prices climb fast; 2, lenders give subprime mortgages; 3, banks bundle mortgages into securities; 4, home prices fall and borrowers default; 5, the securities collapse and banks lose huge sums; 6, Lehman Brothers fails in September 2008 and lending freezes. How the 2008 crisis unfolded 1. Home prices climb fast (2000s) 2. Subprime loans to weak-credit borrowers 3. Banks bundle loans into securities 4. Prices fall borrowers default 5. Securities collapse banks lose huge sums 6. Lehman fails Sept. 2008: lending freezes

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%.

Formula

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.

Worked example

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:

  1. "Percentage points" means simple subtraction—no dividing.
  2. Read the two values: 1929 = 3.2, 1933 = 24.9.
  3. 24.9 - 3.2 = 21.7 percentage points.
  4. Elimination: "about 678%" is the percent change—a different question. 28.1 comes from adding instead of subtracting.
Line graph of U.S. unemployment: 3.2 percent in 1929, 8.7 percent in 1930, 15.9 percent in 1931, 23.6 percent in 1932, and 24.9 percent in 1933. A bracket shows the rise from 1929 to 1933 is 24.9 minus 3.2, which is 21.7 percentage points. U.S. unemployment rate, 1929–1933 0% 5% 10% 15% 20% 25% 30% 1929 1930 1931 1932 1933 Year Unemployment rate 3.2% 8.7% 15.9% 23.6% 24.9% +21.7 points

Answer: 21.7 percentage points.

Worked example

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:

  1. Key features: put people to work + the Government itself hires them.
  2. The WPA directly employed millions of people to build roads, schools, and bridges. ✔
  3. 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.

Worked example

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.

Bar graph of U.S. inflation: 3.2 percent in 1972, 6.2 percent in 1973, and 11.0 percent in 1974. A dashed red line marks the OPEC oil embargo in October 1973, when oil prices roughly quadrupled. Inflation was already rising before the embargo and jumped again after it. Inflation before and after the 1973 oil embargo 0% 2% 4% 6% 8% 10% 12% Inflation rate 3.2% 1972 6.2% 1973 11.0% 1974 Oct. 1973: oil embargo oil prices about ×4

Question: Which conclusion is best supported?

Think-aloud:

  1. Look at the timing: inflation was already rising in 1973 but nearly doubled again in 1974, right after the embargo.
  2. Link the cause: oil is used to make and ship almost everything, so a big jump in oil prices raises many other prices.
  3. 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.

Worked example

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.

Bar graph comparing peak unemployment in two crises: 24.9 percent in 1933 during the Great Depression, when about 9,000 banks failed and deposits were not insured, and 10.0 percent in October 2009 during the Great Recession, when deposit insurance protected savers. Peak unemployment in two crises 0% 5% 10% 15% 20% 25% 30% Peak unemployment rate 24.9% Great Depression (1933, no deposit insurance) 10.0% Great Recession (Oct. 2009, FDIC insurance)

Question: Which statement does the evidence from both sources support?

Think-aloud:

  1. Put facts side by side: 24.9% vs. 10.0%; thousands of bank failures with no insurance vs. insured deposits.
  2. A reasonable connection: a reform created during the first crisis (deposit insurance) helped limit damage in the second.
  3. 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 mistake

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.
Test strategy

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.

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.
