Economic Cycles Explained: Phases, Causes & Indicators

Key Takeaways

• Economic cycles explained in one sentence: an economic cycle is the recurring but irregular pattern of expansion and contraction in overall economic activity (output, employment, income, and spending) around a longer-run growth trend. Cycles vary widely in length and severity and follow no fixed schedule.

• Dating happens after the fact. In the United States, the National Bureau of Economic Research (NBER), a private nonprofit, identifies official peaks and troughs, usually months after they occur. Neither "the government" nor a news headline declares a recession in real time.

• Rules of thumb are not the official method. "Two straight quarters of falling GDP" is a popular shortcut, not NBER's approach, and no single indicator (the yield curve, the Sahm rule, jobless claims) reliably forecasts recessions.

• Different cycles run on different clocks. The economic cycle is not the same as the stock market cycle, the credit cycle, or the housing cycle, and they often move out of step with one another.

• Policy moderates cycles; it does not eliminate them. Central-bank and fiscal policy can soften downturns and cool overheating, but they work with lags, trade-offs, and real disagreement among economists.

Economic Cycles Explained at a Glance

The table below summarizes the core ideas. Each row is expanded later in the guide.

What Are Economic Cycles?

An economic cycle is the recurring but irregular pattern of expansion and contraction in a country's overall economic activity, measured by output, employment, income, and spending, around its longer-run growth trend. Cycles differ in length and severity, and they follow no fixed schedule.

"Cycle" is a convention, not a promise of repetition. The word describes a pattern economists see in the data: periods when activity rises across many parts of the economy, followed by periods when it falls broadly, followed by renewed growth. The sequence recurs, but it is not periodic. Some expansions last a few years and others last a decade or more.

What is the difference between an economic cycle and a business cycle?

There is almost no difference. Most sources use the two terms interchangeably. This guide uses "economic cycle" throughout and uses "business cycle" only when naming NBER's work, such as its Business Cycle Dating Committee.

How is a cycle different from a trend?

The trend is the economy's longer-run growth path, driven by factors such as the size of the labor force, the amount of capital, and productivity. The cycle is the up-and-down movement around that path. In an expansion, activity runs above where it was before; in a contraction, activity falls, sometimes below its previous level for a long while.

Why are economic cycles irregular?

Economic cycles are irregular because each one is shaped by different shocks, policies, and conditions. An oil-price spike, a housing-finance problem, a pandemic, and a change in interest rates are very different events, so the resulting downturns differ in cause, depth, and length. Economists generally reject the idea that expansions "die of old age" simply because they have lasted a long time.

Why do economic cycles matter to ordinary people?

Economic cycles matter because they shape job availability, wage growth, prices, borrowing costs, and the value of savings and investments. The effects are uneven: workers in cyclical industries, younger job seekers, small businesses, and households with little savings often feel downturns differently from others.

A brief analogy, offered only as an illustration and not as a model of the economy: think of weather rather than a clock. Seasons recur in broad patterns, but no two storms are alike, and forecasting any specific day is much harder than describing the general pattern.

What Are the Phases of the Economic Cycle?

The economic cycle is commonly described in four phases:

1. Expansion: overall activity rises.

2. Peak: activity reaches its high point before turning down.

3. Contraction (recession): activity declines broadly across the economy.

4. Trough: activity bottoms out, after which recovery and a new expansion begin.

This four-phase model is a teaching framework. NBER's official chronology identifies only two turning points, peaks and troughs. Expansions are the periods between a trough and a peak, and recessions are the periods between a peak and a trough. "Recovery" is an informal label for the early part of an expansion, not an official NBER phase.

Expansion: what happens when the economy grows?

Expansion is the phase in which overall economic activity is rising: output, employment, income, and spending grow. Typically, hiring increases, unemployment tends to fall, businesses invest, credit expands, and consumers spend more. Inflation may stay stable or build as demand presses on available workers and capacity, and central banks may raise interest rates if price pressures grow.

Caveat: NBER describes expansion as the economy's normal state, but gains are not shared equally across sectors, regions, or income groups.

Peak: what is the top of the cycle?

A peak is the month when overall economic activity reaches its highest level before a contraction begins. By NBER's convention, the peak month is the last month of the expansion. Near a peak, labor markets are often tight, capacity can be stretched, and interest rates may be relatively high.

Caveat: A peak can only be identified in hindsight. A tight job market or high spending is not proof that a peak has arrived.

Contraction: what happens during a recession?

A contraction, or recession, is the stretch between a peak and the next trough during which activity declines broadly across the economy. Typically, output falls, job growth stalls or turns negative, unemployment rises, and spending and business investment pull back. Inflation often eases, though not always. Central banks tend to lower interest rates, and fiscal support rises, partly through automatic stabilizers such as unemployment insurance.

Caveat: Severity varies enormously. According to NBER, most recessions are brief, but some are deep and prolonged.

Trough and recovery: when does the economy bottom out?

A trough is the month when overall economic activity reaches its lowest point, after which an expansion begins. By NBER's convention, the trough month is the last month of the recession. Recovery is the informal label for the rebuilding that follows.

Caveat: NBER notes that the time it takes to return to the previous peak level of activity, or to the previous trend path, may be quite extended. Employment and household incomes often lag a rebound in GDP.

Phase summary table

How Are Economic Cycles Measured and Dated?

In the United States, economic cycles are dated by NBER's Business Cycle Dating Committee, which identifies the months of peaks and troughs using a range of economy-wide measures. The committee's approach is retrospective: it waits until enough data are available to avoid major revisions.

Who decides when a recession starts?

No one declares a recession in real time. NBER, a private nonprofit research organization, dates US peaks and troughs after the fact, often many months later. Federal statistical agencies such as the Bureau of Economic Analysis (BEA) and the Bureau of Labor Statistics (BLS) publish the data the committee uses, but they do not date cycles. Neither the White House nor Congress declares recessions.

How does NBER decide whether a recession occurred?

NBER defines a recession as a significant decline in economic activity that is spread across the economy and lasts more than a few months. The committee weighs three criteria, depth, diffusion, and duration, as somewhat interchangeable: an extreme reading on one can partly offset weaker readings on another.

The committee emphasizes economy-wide measures rather than any single number. These include real personal income less transfers, nonfarm payroll employment, household-survey employment, real personal consumption expenditures, manufacturing and trade sales adjusted for price changes, and industrial production. There is no fixed rule about how these are weighted, though in recent decades the committee has put the most weight on real personal income less transfers and payroll employment. For quarterly dating, it also considers GDP and gross domestic income (GDI), the income-side measure of the economy.

Is two quarters of negative GDP a recession?

No, not by the official US method. Two consecutive quarters of declining real GDP is a common rule of thumb, and some countries and news outlets use it, but NBER does not. Gross domestic product (GDP) is the total market value of goods and services produced in a country over a period.

The two approaches can disagree in both directions. In 2020, the decline in activity was so deep and widespread that NBER classified it as a recession even though it lasted only two months. In the first half of 2022, BEA's initial GDP estimates showed two consecutive quarterly declines, yet NBER's chronology, as checked in October 2026, lists no recession in that year.

Why are cycle dates and GDP figures revised?

Because early data are incomplete, agencies revise their estimates as better information arrives. BEA publishes successive GDP estimates and later annual updates, which can change how a past quarter looks. This is one reason NBER waits before announcing turning points.

How do other countries date their cycles?

Approaches differ. In the euro area, the Euro Area Business Cycle Dating Committee of the Centre for Economic Policy Research (CEPR) dates peaks and troughs in a manner similar to NBER's. Other countries rely on statistical agencies, central banks, or simple rules such as the two-quarter convention. Comparing recession dates across countries requires checking which method each uses.

What Causes Economic Cycles?

Economic cycles have no single cause. They arise from a mix of shocks, policy changes, and the way households, businesses, and lenders respond to them, and each downturn has a different combination of triggers.

• Demand shocks: sudden changes in spending by households, businesses, governments, or foreign buyers.

• Supply shocks: disruptions to production or input costs, such as energy-price spikes or supply-chain breakdowns.

• Monetary-policy changes: shifts in interest rates and credit conditions that raise or lower borrowing and spending.

• Credit and financial stress: lending booms and busts, falling asset values, and strained banks can amplify downturns.

• Confidence and expectations: changes in how optimistic or cautious people are can reinforce spending or pullbacks.

• Inventories: businesses that overbuild or cut stock sharply can exaggerate swings in output.

• External shocks: pandemics, wars, natural disasters, and global events.

What do economists' main theories say?

Economists disagree about which forces matter most, and the frameworks below are best read as complementary or competing lenses, not settled consensus.

• Keynesian views emphasize swings in total demand and the possibility that economies stay below capacity for extended periods.

• Monetarist views emphasize the role of money and credit conditions in driving activity and prices.

• Real business cycle theory emphasizes changes in productivity and technology as drivers of fluctuations.

• Financial-instability perspectives emphasize how credit expansion and balance-sheet stress can build vulnerabilities that later unwind.

No one theory explains every downturn. Reading a given recession usually means asking which of these forces were most important at the time.

Economic Cycles vs. Related Concepts

The economic cycle is not the same as the stock market cycle, the credit cycle, or the housing cycle. Each tracks a different thing and runs on its own timescale, and they can diverge, sometimes for long stretches.

Some researchers have proposed much longer "long wave" cycles, but these theories are contested and are not part of mainstream business-cycle dating.

Recession vs. depression vs. bear market vs. correction vs. slowdown vs. stagflation

These terms describe different things, and mixing them up is a common source of confusion.

A bear market does not always signal a recession, and a recession does not always include a bear market.

Which Economic Indicators Signal Where We Are in the Cycle?

Economists sort indicators by timing: leading indicators tend to change before the economy turns, coincident indicators move with it, and lagging indicators change afterward. Classifications vary by source. The groupings below follow The Conference Board, a private research group whose Leading Economic Index combines 10 components and whose Coincident Economic Index combines four (payroll employment, personal income less transfers, industrial production, and manufacturing and trade sales).

Does an inverted yield curve predict a recession?

Not reliably. A yield curve plots the interest rates on Treasury securities of different maturities, and the curve is "inverted" when short-term yields exceed long-term yields. Historically, inversions have preceded most US recessions since the mid-twentieth century, according to Federal Reserve research, but the lead time varies from many months to roughly two years, and false signals have occurred.

Two spreads are widely used. The New York Fed's recession-probability model uses the 10-year Treasury yield minus the 3-month yield, while news coverage often cites the 10-year minus the 2-year spread. They can give different readings at the same time. An extended inversion that began in late 2022 had not, as of NBER's chronology checked in October 2026, been followed by an NBER-dated recession, though NBER dates turning points only after the fact. Whether any inversion was a true or false signal is known only in hindsight, and the curve says nothing about how deep or long a downturn might be.

What is the Sahm rule?

The Sahm rule is a rule of thumb, devised by economist Claudia Sahm, that signals the start of a recession when the three-month moving average of the national unemployment rate rises by 0.50 percentage points or more above its lowest level of the previous 12 months, according to the FRED data notes.

Its limits are real. It rests on a small number of past recessions. The real-time version reached 0.53 in July 2024, above the 0.50 threshold, and NBER's chronology checked in October 2026 lists no peak after February 2020, although NBER's retrospective dating means that could change. Unemployment can also rise for reasons unrelated to a downturn, such as more people entering the labor force, and the underlying data are revised each January.

How can I check current conditions myself?

The most reliable approach is to read the primary releases directly rather than headlines. These are typically published on a regular schedule:

• BEA, Gross Domestic Product: quarterly, with later revisions.

• BLS, Employment Situation: monthly payrolls and the unemployment rate.

• BLS, Consumer Price Index: monthly inflation.

• Department of Labor, weekly jobless claims: weekly.

• FRED (Federal Reserve Bank of St. Louis): charts and data for most series above, including yield-curve spreads and the Sahm rule.

• Federal Reserve: FOMC statements and the Beige Book, a periodic summary of regional business conditions.

• The Conference Board: monthly Leading, Coincident, and Lagging Economic Index releases.

• NBER: the only source of official US recession dates.

How Long Do Economic Cycles Last?

There is no standard length. According to NBER's US chronology, expansions have averaged about 64 months and contractions about 10 months since 1945, but individual cycles range widely, and averages hide that variation.

Source: NBER, US Business Cycle Expansions and Contractions (data last updated March 2023).

The spread within these averages is large. Among postwar contractions, the shortest was two months (February to April 2020) and the longest was 18 months (December 2007 to June 2009). Postwar expansions ranged from 12 months (July 1980 to July 1981) to 128 months (June 2009 to February 2020), the longest in the NBER record. The longest contraction in the chronology, 65 months, ran from 1873 to 1879.

Comparing eras requires care. Measurement was less complete before World War II, and research by economist Joseph Davis for NBER found that the prewar chronology is open to question and that a revised annual chronology shows smaller differences between eras. Economists continue to debate how much of the postwar change reflects real structural shifts, policy, or measurement.

How Do Central Banks and Governments Respond to Economic Cycles?

Central banks respond mainly by adjusting interest rates and financial conditions, and governments respond through spending and tax choices, plus automatic stabilizers that act without new legislation. Neither can prevent recessions or fine-tune the economy.

Monetary policy is the use of interest rates and related tools by a central bank to influence borrowing, spending, employment, and inflation. In the United States, the Federal Reserve, an independent central bank, conducts monetary policy. Its Federal Open Market Committee (FOMC) states that its strategy aims to promote maximum employment and stable prices, and it defines the longer-run inflation goal as 2 percent, measured by the personal consumption expenditures price index (FOMC statement, last updated August 2025). The FOMC also notes that policy actions affect activity, employment, and prices with a lag.

Fiscal policy is the use of government spending and taxation to influence the economy. In the United States, Congress and the President set it through legislation, and the Treasury carries out much of it.

Automatic stabilizers are features of the tax and benefit system that cushion swings in activity without new laws. When incomes fall, tax payments decline and benefits such as unemployment insurance tend to rise, which supports household spending.

Economists disagree about how large and how fast policy responses should be, how to weigh inflation against employment, and how to treat government debt. A soft landing is an outcome in which inflation is brought down without a recession. It is a description of an outcome, not a guaranteed result of any policy.

How Do Economic Cycles Affect Jobs, Prices, Interest Rates, and Investments?

Economic cycles affect people through jobs, prices, borrowing costs, and asset values, but not equally. Effects depend on a person's industry, region, age, savings, debts, and time horizon.

• Workers: hiring and wage growth tend to be stronger in expansions; layoffs and slower hiring are more common in contractions. Workers in cyclical industries, such as construction, manufacturing, and travel, are often described as more exposed than workers in industries with steadier demand, such as health care and food retail.

• Savers: interest rates on savings often rise when central banks tighten policy and fall when they ease, while inflation reduces what savings can buy.

• Borrowers: loan and mortgage costs are influenced by interest rates, which change over the cycle; housing activity is often sensitive to those changes.

• Business owners: sales, credit availability, and hiring conditions shift with the cycle, and small businesses with thinner cash reserves often feel downturns sooner.

• Investors: stock prices tend to move ahead of the economy because they reflect expectations, so markets can fall before a recession is visible and rise before a recovery is felt.

Investor-education sources such as Investor.gov describe a few widely accepted principles: diversifying investments, matching investments to a time horizon, and keeping emergency savings for short-term needs. These are general principles, not recommendations for any individual.

Four Real U.S. Downturns Show Why No Two Cycles Are Alike

No two recessions share the same cause, length, or shape. The four snapshots below use NBER's turning-point months and durations.

• 1973–75 (November 1973 to March 1975, 16 months): an energy-price shock and high inflation coincided with weak output, a pattern later labeled stagflation.

• 1981–82 (July 1981 to November 1982, 16 months): followed a period of tight monetary policy aimed at bringing down high inflation; economists continue to discuss the trade-offs involved.

• 2007–09 (December 2007 to June 2009, 18 months): rooted in housing and financial-system stress, and the longest contraction of the postwar era in NBER's table.

• 2020 (February to April 2020, 2 months): triggered by the pandemic, and the shortest contraction in the NBER chronology; NBER classified it as a recession because the decline was so deep and widespread.

Illustrative Examples (Hypothetical)

The four scenarios below are hypothetical. The numbers are round and invented, and none is real data or advice.

1. A household reviews its cushion. A household reads that several leading indicators have weakened. It notes that its savings equal about three months of expenses and that it has a variable-rate debt. Takeaway: leading-indicator news is a prompt to look at one's own finances, and it does not by itself show what will happen.

2. A small-business owner manages a slowdown. A shop owner sees orders soften for two months. The owner reviews inventory levels and hiring plans against recent sales. Takeaway: businesses often adjust inventory and hiring step by step as conditions become clearer, rather than reacting to a single report.

3. A new investor faces a bear market in a growing economy. A new investor sees stock prices fall about 20% while unemployment remains low and GDP is still growing. Takeaway: markets and the economy can diverge, and a falling market is not an official signal of a recession.

4. A worker in a cyclical industry watches job conditions. A worker in a construction-related field notes that job openings are shrinking locally. The worker looks at local postings and national releases together. Takeaway: national data and local conditions can differ, and both matter for personal decisions.

Common Mistakes When Reading the Economy

Most errors in reading the economy are habits of thinking rather than gaps in knowledge. These are ten common ones.

1. Extrapolating the current phase forever. Assuming that strong or weak conditions will simply continue.

2. Reading one month as a trend. Monthly data are noisy and often revised, so a single release can mislead.

3. Overlooking revisions. Treating first estimates as final, when agencies routinely update them.

4. Following only alarming headlines. Checking data mainly when news coverage is intense, instead of on a steady schedule.

5. Ignoring inflation and real incomes. Looking at dollar amounts without asking what they can buy.

6. Assuming the next cycle will repeat the last one. Each downturn has different causes and a different shape.

7. Assuming policy works instantly. Rate changes and fiscal measures act with lags.

8. Ignoring personal and local conditions. National averages can differ from what happens in a particular industry or region.

9. Waiting for official confirmation before reviewing one's own finances. Official dating arrives months late, while personal circumstances change in real time.

10. Mixing time horizons. Treating money needed soon and money meant for the long term as the same question.

Common Misconceptions

Myth: Economic cycles run like clockwork. Reality: Cycles are irregular in length and severity. Takeaway: Treat averages as a description of history, not a schedule.

Myth: Two negative GDP quarters is the official definition of a recession. Reality: It is a rule of thumb; NBER weighs depth, diffusion, and duration across many measures. Takeaway: Look for NBER's announcements for official US dates.

Myth: The government or the President declares recessions. Reality: NBER, a private nonprofit, dates US recessions retrospectively. Takeaway: Official confirmation typically lags events by months.

Myth: The stock market is the economy. Reality: Stock prices reflect expectations about future profits and can diverge from output and jobs. Takeaway: Read market data and economic data separately.

Myth: A bear market always means a recession. Reality: Stock declines have occurred without recessions, and recessions have begun without prior bear markets. Takeaway: Neither event reliably implies the other.

Myth: Expansions die of old age. Reality: Length alone does not end an expansion; shocks, policy changes, and imbalances do. Takeaway: Duration is not a countdown.

Myth: The yield curve (or any one indicator) is a crystal ball. Reality: Every single indicator has false signals, revisions, and variable lead times. Takeaway: Use several indicators and treat each as one input.

Myth: Central banks can end the cycle. Reality: Policy can moderate swings but works with lags and trade-offs. Takeaway: Expect cycles to continue, with policy influencing their shape.

Myth: Recessions hit everyone equally. Reality: Effects differ by industry, region, age, and savings. Takeaway: National figures describe averages, not individual experiences.

Myth: GDP recovery means everyone is better off. Reality: Employment and incomes often lag a GDP rebound. Takeaway: Check jobs and real income, not only output.

Myth: Inflation only happens in booms. Reality: Inflation can be high during weak growth, as in stagflation. Takeaway: Inflation and growth can move independently.

Myth: Low unemployment guarantees continued growth. Reality: Unemployment often lags activity, and it can be low near a peak. Takeaway: Treat it as one reading among several.

Myth: A recession equals a depression. Reality: Depression is an informal term with no official definition. Takeaway: Use the terms carefully and ask what a speaker means.

Myth: All countries share one cycle. Reality: Countries have separate cycles that are linked by trade, finance, and shared shocks. Takeaway: Check which country and which dating method a claim refers to.

Quick-Start Checklist: How Can I Follow the Economy Without Overreacting?

These questions are a starting point for thinking, not advice.

• Which official releases will I check, and how often?

• Do I know the difference between a market move and an economic data release?

• Have I reviewed my own emergency savings and debts?

• Is my time horizon for each financial goal clear?

• Do I know where to verify current rules, data, and NBER announcements?

Conclusion

Economic cycles are the recurring but irregular swings of overall economic activity around a longer-run trend. They have recognizable phases, but they do not follow a schedule, and each downturn has its own causes. NBER dates US turning points after the fact, while agencies such as BEA and BLS publish the data behind them. Indicators such as the yield curve and the Sahm rule offer useful signals with honest limits, and central banks and governments can moderate but not eliminate cycles. Reading the economy well means using primary sources, several indicators, and a calm, long view. Readers should check current data directly at the sources named here and consult qualified professionals for personal decisions.

Frequently Asked Questions

How many phases are in the economic cycle?

Textbooks describe four: expansion, peak, contraction, and trough. NBER's official chronology marks only two turning points, peaks and troughs, with expansions and recessions between them. "Recovery" is an informal label for the early part of an expansion, not a separate official phase.

Can economic cycles be predicted?

Not reliably. Economists can describe current conditions and estimate risks, but the timing and severity of turning points are hard to forecast. Indicators have mixed records, with false signals and variable lead times, and shocks such as pandemics or wars cannot be anticipated in advance.

Are all countries on the same economic cycle?

No. Each country's cycle is shaped by its own policies, industries, and shocks. Trade and finance link economies, and global events can push many in the same direction at once, but timing and depth differ. Dating methods also vary between countries.

What is a soft landing?

A soft landing is an outcome in which inflation falls without a recession. It is identified in hindsight, and central banks may aim for it, but no policy guarantees it. Economists disagree about how achievable it is in any given episode.

What is stagflation?

Stagflation is weak economic growth and high unemployment occurring together with high inflation. It complicates policy because efforts to fight inflation can weaken the job market, while efforts to support jobs can add price pressure. The 1970s are the standard historical example.

Which yield-curve spread is the better recession signal?

Research from the Federal Reserve Bank of San Francisco favors the 10-year minus 3-month spread on economic and empirical grounds, and the New York Fed's model uses it. The 10-year minus 2-year spread is also widely cited. Neither is infallible, and they can disagree.

Is a recession the same as a bear market?

No. A recession is a broad decline in economic activity dated by NBER, while a bear market is a prolonged fall in stock prices, commonly 20% or more from a high. They can occur separately, and markets often move ahead of the economy.

How do economic cycles affect interest rates?

Interest rates tend to rise when policymakers want to cool inflation in strong expansions and fall when they want to support activity in downturns. Market rates also reflect expectations and other factors, so rates do not follow the cycle in a fixed pattern.

How do economic cycles affect the housing market?

Housing is sensitive to interest rates, incomes, and confidence, so its activity often shifts with the cycle. Local conditions matter a great deal, and the housing cycle can run ahead of, behind, or apart from the broader economic cycle.

How do recessions affect jobs and wages?

Recessions typically bring slower hiring, more layoffs, and weaker wage growth, though effects vary by industry and region. Employment often keeps recovering for some time after output begins to rise, so job markets can feel the downturn longer than GDP suggests.

Why does inflation matter when reading the economic cycle?

Inflation determines what incomes and savings can actually buy, so real (inflation-adjusted) measures matter more than dollar totals. Inflation often builds late in expansions and eases in recessions, but it can also remain high when growth is weak.

Can the Federal Reserve prevent a recession?

No. The Federal Reserve can influence borrowing costs and financial conditions to support employment and stable prices, but its actions work with lags and uncertain effects, and it cannot control shocks such as energy disruptions or pandemics.

What is the difference between GDP and GDI?

GDP measures the value of goods and services produced, while gross domestic income (GDI) measures the income generated in producing them. In theory they match, but in practice estimates differ, so NBER considers both when dating quarterly turning points.

What are leading and lagging indicators?

Leading indicators, such as building permits and jobless claims, tend to change before the economy turns. Lagging indicators, such as measures of inflation or the length of unemployment, tend to change after. Classification varies by source, so check the publisher's definitions.

How can households think about preparing for a downturn?

Educational sources commonly discuss building emergency savings, understanding the terms of debts, tracking fixed expenses, and matching money needed soon to stable options. This is general information, not advice, and a qualified professional can address individual circumstances.

How can small businesses think about preparing for a downturn?

Small-business educators commonly discuss maintaining cash reserves, managing inventory and credit lines, and watching dependence on a few customers. These are general topics, not advice, and an accountant or adviser can help with a specific business.

Where can I check whether the economy is in a recession?

NBER's Business Cycle Dating Committee announcements are the official source for US recession dates, though they arrive after the fact. For current conditions, read BEA GDP releases, BLS employment and inflation reports, and FRED charts directly.

What is the difference between a recession and a depression?

A recession is a significant, broad decline in economic activity lasting more than a few months, dated by NBER. A depression is an informal term for a far more severe and prolonged downturn, with no official threshold. The 1929–33 contraction lasted 43 months in NBER's table.
