What is a recession?
A recession is a broad fall in economic activity — output, jobs, incomes and spending — that lasts more than a few months. In the US the dates are set by economists at the NBER, not by a rule of “two quarters of falling GDP”. They have dated 34 recessions since 1857. The 13 since 1945 lasted 10.2 months on average; the latest one, 2020, lasted 2 months.
13 of them since 1945; the latest followed the peak in February 2020

What a recession is, and who decides
A recession is a significant decline in economic activity that spreads across the economy and lasts more than a few months. Production, jobs, incomes and sales fall together, in most industries at once. The stretch between two recessions, when the economy grows, is called an expansion.
The US government has no official definition. The dates everyone uses come from the Business Cycle Dating Committee of the National Bureau of Economic Research (NBER), a private, non-partisan research organization. The committee picks two months: the peak, when activity was highest, and the trough, when it was lowest. The recession runs from the month after the peak to the trough.
What the committee weighs
It looks mostly at monthly data: employment in the payroll and household surveys, personal income excluding government transfers, consumer spending and business sales after inflation, and industrial production. Quarterly GDP counts too, as one measure among several.
“Two quarters in a row of falling GDP” is a popular rule of thumb, not the definition. In 2022 the first estimates showed GDP falling in two quarters, yet payroll employment grew by 2.54M jobs in the first half of the year, and the NBER dated no recession. The 2001 recession, on the other hand, has no two consecutive quarters of falling GDP in today's data.
The committee announces its dates only when the data leave no doubt — months, sometimes more than a year, after the turn. A recession is usually under way, or even over, before it is official.
Every US recession since 1857
Each line below is a decade and each red stripe a recession, from the one that followed the peak in June 1857 to the latest. In the 19th century the economy spent much of its time shrinking: 48% of the months from June 1857 to the end of 1899 fell in a recession. The longest on record, from October 1873 to March 1879, the Long Depression, lasted 65 months; the second longest, 1929–33, the Great Depression, 43 months.
Since 1945 recessions have come less often and ended sooner. A new one began every 6.2 years on average, against every 4.0 years before, and the economy spent 13% of the months in recession, against 42% before 1945. The 2010s were the first whole decade without a single month of recession.

How long recessions and expansions last
Since 1945 the average recession has lasted 10.2 months, from 2 months (2020) to 18 months (2008–09). The 21 recessions before 1945 lasted 21.2 months on average.
Expansions stretched out even more: 64.2 months on average since 1945, about 5.3 years, against 28.9 months before. The longest on record ran 128 months, from June 2009 to February 2020. The current expansion began in May 2020 and had lasted 78 months by October 2026 — longer than all but 5 of the 33 completed ones.
The latest recession, and today
The latest recession in the NBER's table followed the peak in February 2020 and ended with the trough in April 2020: 2 months, the shortest on record. Payroll employment fell by 21.9M (−14.4%) from February 2020 to April 2020, unemployment rose from 3.5% to 14.8% in April 2020, and the S&P 500's monthly average fell by 19%. Payrolls were back at their pre-recession high in June 2022, 28 months after the peak.
Since then the economy has been in an expansion as far as the NBER's table goes (checked November 9, 2026). In October 2026 unemployment was 4.1%, against 4.4% in September 2025, and payroll employment changed by +885K jobs from October 2025 to October 2026. The committee dates turning points only in hindsight, so monthly numbers show the direction, not an official verdict.
What happens to jobs and stocks in a recession
Below is every recession since 1948 on its own card, from a year before the peak to 3 years after it. Unemployment rose by 2.2 points at the least (1980) and 11.3 at the most (2020); the median rise was 3.6 points. The biggest loss of jobs, 21.9M or 14.4% of all payroll jobs, came in 2020.
Stocks usually moved first: in 11 of the 12 recessions the S&P 500 began its fall before the economy's peak. Its deepest fall around each recession ranged from −10% (1960–61) to −51% (2008–09), −18% in the median case. And in 6 of them the index stood higher at the trough than at the peak: much of the fall came before the recession began, and the rebound before it ended.

Unemployment: the lowest rate in the 12 months up to the peak and the highest in the 36 months after it (or until the next peak). Jobs: payroll employment from its high around the peak to its low after it; “back after”: months from the peak until payrolls regained that high. S&P 500: price, monthly averages of daily closes, so falls measured from daily closes were deeper.
Stocks turn first, jobs last
Line the recessions up at their end, the trough. The S&P 500 hit its low before the recession was over in all 12, a median 4 months earlier. Unemployment peaked in the recession's last month or later in all 12 — up to 19 months after the trough (2001). By the time jobs come back, stocks have usually been rising for a while.
12 recessions are a small sample: this is history, not a timing rule.
Questions people ask
Are we in a recession now?
Not according to the NBER's table (checked November 9, 2026): its latest date is the trough in April 2020, so the expansion that began after it is still the current one. The committee dates turning points months after they happen. In October 2026 unemployment was 4.1%, against 4.4% in September 2025, and payroll employment changed by +885K jobs from October 2025 to October 2026.
Is a recession two quarters of negative GDP?
No, that is a rule of thumb. The NBER looks month by month at jobs, incomes, spending, sales and industrial production, and asks how deep, how widespread and how long the decline is. The two falling quarters in the first GDP estimates of 2022 were not a recession; the 2001 recession had no two falling quarters in today's data.
How long does a recession last?
Since 1945, 10.2 months on average, from 2 months to 18 months. Before 1945 recessions lasted 21.2 months on average; the longest, 1873–79, lasted 65 months.
How often do recessions happen?
There have been 13 US recessions since 1945, one every 6.2 years on average, and 34 since 1857. Since 1945 the economy has been in recession 13% of the time; before 1945, 42%.
What happens to the stock market in a recession?
Around each of the 12 recessions since 1948 the S&P 500's monthly average fell by 10% to 51% at the deepest, 18% in the median case. It usually began falling before the recession and hit bottom before it ended, so in 6 of them it stood higher at the trough than at the peak.

How the numbers are calculated
- Recession dates: NBER Business Cycle Dating Committee, US Business Cycle Expansions and Contractions: monthly peaks and troughs since June 1857 (table checked November 9, 2026).
- Unemployment rate (series UNRATE, since 1948) and nonfarm payroll employment (PAYEMS), seasonally adjusted: U.S. Bureau of Labor Statistics, retrieved from FRED, Federal Reserve Bank of St. Louis.
- S&P 500: Robert J. Shiller, Online Data (Yale University), the S&P Composite price as monthly averages of daily closes.
- A recession runs from the month after the peak through the trough. Its length is the months from peak to trough, an expansion's the months from a trough to the next peak, as the NBER counts them. “Since 1945”: recessions whose peak came in 1945 or later.
- Around each recession since 1948: unemployment from its lowest rate in the 12 months up to the peak to its highest in the 36 months after it (never past the next peak); payroll jobs from their highest level between 12 months before the peak and the trough to their lowest after it; the S&P 500's deepest fall from 12 months before the peak to 6 months after the trough.
- BLS data: Civilian unemployment rate, 16 years and over, seasonally adjusted (BLS LNS14000000). Months without a published value are left out (2025-10).
- Shiller's notes on the latest months: Oct price is Oct 2nd close; Sept/Oct CPI estimated; Oct GS10 is Oct 2nd value.
