The term "recession" gets used casually to describe almost any bad economic news, but economists apply a more precise definition when determining whether one is actually underway.
The common shorthand -- and its limits
A widely cited rule of thumb defines a recession as two consecutive quarters of declining gross domestic product (GDP). It's a useful shorthand, but it isn't the official U.S. standard, and it can miss downturns that don't fit that exact pattern.
How recessions are officially determined in the U.S.
In the United States, the nonprofit National Bureau of Economic Research (NBER) is the body most commonly cited as the official arbiter of recession dates. Its Business Cycle Dating Committee looks at a broad set of monthly indicators rather than GDP alone, including:
- Employment levels
- Real personal income
- Industrial production
- Retail and wholesale sales
The NBER defines a recession as a significant decline in economic activity that is spread across the economy and lasts more than a few months. Because it relies on multiple data series and revisions, the NBER often doesn't declare a recession's start date until months after it has actually begun.
What typically happens during a recession
Recessions are commonly associated with rising unemployment, falling business investment, and declining consumer spending. Their length and severity vary widely -- some are short and mild, while others, like the downturns associated with 2008 and 2020, are deep and prolonged.
Why the distinction matters
Because a recession is formally declared only in hindsight, policymakers, businesses, and consumers often have to make decisions under uncertainty about whether a downturn is actually occurring. That uncertainty is part of why economic indicators -- jobs reports, inflation data, and GDP estimates -- draw so much attention when they're released.
Leading indicators economists watch
Beyond the NBER's official determination, economists and investors track a range of leading indicators that can signal a recession may be approaching, including the unemployment rate's trajectory, manufacturing activity surveys, consumer confidence measures, and the shape of the Treasury yield curve. No single indicator reliably predicts every downturn, which is part of why economists often disagree about recession risk in real time.
How recessions compare in severity
Not all recessions look alike. Some, such as the brief downturn in the early 1990s, were relatively mild and short. Others, including the 2007-2009 financial crisis and the sharp but short 2020 pandemic-driven downturn, involved much larger job losses and economic disruption. The NBER's dating identifies when a recession started and ended but does not, by itself, measure severity -- that requires looking at the underlying economic data.
What policymakers can do
Both fiscal policy (tax and spending decisions made by Congress and the president) and monetary policy (interest rate decisions made by the Federal Reserve) are commonly used tools intended to shorten or soften recessions, such as lowering interest rates to encourage borrowing or approving stimulus spending to support demand. The effectiveness and timing of these tools is a frequent subject of economic and political debate.
How recessions affect different parts of the economy
Recessions don't affect every sector equally. Industries tied closely to consumer discretionary spending, such as retail, travel, and housing construction, often see sharper pullbacks than sectors providing essential goods and services, such as utilities and healthcare. Labor markets also tend to show uneven effects, with layoffs typically concentrated first in cyclical industries before potentially spreading more broadly if a downturn deepens.
The jobs recovery pattern
Economists frequently distinguish between the technical end of a recession -- when GDP and other broad indicators stop declining and begin growing again -- and a full "jobs recovery," when employment returns to its pre-recession level. In some past downturns, job market recovery has significantly lagged the technical end of the recession, a pattern sometimes referred to as a "jobless recovery," which is part of why unemployment data remains closely watched even after GDP growth resumes.
International context
While the NBER's dating methodology is specific to the United States, other countries and international organizations, including the International Monetary Fund and individual national statistical agencies, use their own criteria -- sometimes more closely aligned with the simpler two-consecutive-quarters GDP decline definition -- to assess recessions in their own economies, which can occasionally lead to differing public characterizations of the same global economic period.
