What exactly is a recession? Economists say odds of one in the US are high.

A report showing the U.S. economy contracted at the start of the year as businesses raced to import goods ahead of President Donald Trump's widespread tariffs gave fuel to forecasts the economy is likely to cool and could potentially tip into a mild recession.

But what exactly is a recession?

What is the definition of a recession?

The National Bureau of Economic Research (NBER) defines a recession as a “significant decline in economic activity that is spread across the economy, lasting more than a few months.” Three criteria – depth, diffusion, and duration – need to be met individually to some degree to formally identify a recession, according to the NBER.

The committee considers several factors including real incomepayroll employmentconsumer spending, industrial production, and gross domestic product when making its determinations.

“Most of the recessions identified by our procedures do consist of two or more consecutive quarters of declining real GDP, but not all of them,” NBER explains on its website.

What are the odds of a recession?

The odds of a recession are "very high," Steve Blitz, managing director of global macro strategies and chief U.S. economist at Global Data previously told USA TODAY. In early April, Trump threatened an additional 50% tariff on goods imported from China if it did not withdraw its retaliatory tariffs after the president put levies on nearly every country in the world.

While Trump's tariff plans have changed several times since then, experts expect these decisions to ultimately bring higher costs and lay offs to American workers as consumer and business sentiment falls. The tariff talks have also frequently rocked financial markets. After Trump's tariffs announcement in early April, the stock market lost about $6.6 trillion over a two day span — the largest two-day wipeout of shareholder value on record, according to MarketWatch.

Trump's Treasury Secretary Scott Bessent downplayed the stock market drop at the time in an interview with NBC News' 'Meet the Press' Sunday, pointing to data released the previous Friday showing higher-than-anticipated job growth in March.

"We could see from the jobs number on Friday, that was well above expectations, that we are moving forward, so I see no reason that we have to price in a recession," Bessent said.

But one look at social media shows many Americans fear we have already entered one. Still, TikToks and stock prices don't officially determine when the country enters a recession, and the word does have an actual definition worth knowing.
