There's no single definition of an economic recession, though recessions are commonly identified by two consecutive quarters of shrinking gross domestic product.

A recession is commonly defined as two straight quarters of shrinking GDP

Recessions are sustained downturns in the economy. They’re significant, widespread, and there’s no single, surefire way to define or predict them.

One signal that a recession has become a depression? When GDP declines more than 10%

There’s no single definition for recessions or depressions, but both are marked by sustained periods of declining economic activity. Depressions are more severe than recessions.

The clearest sign of a recession is a steady increase in job losses and high unemployment.

The US has been through 34 recessions since 1854

From 1855 to 2020, the average US recession lasted for an average of 17 months. But in the 20th and 21st centuries, the average recession length has shortened, decreasing to 14 months.

Roughly $5T of stimulus money flooded the economy during the pandemic

Recessions can last anywhere from months to years. To encourage economic growth, governments use policy levers such as lowering interest rates or introducing a stimulus. Economists credit massive stimulus funds for helping the economy quickly recover from a recession during the COVID-19 pandemic.

Recessions are considered to be inevitable by modern economic standards

Recessions are caused by imbalances in the market and are guaranteed to happen in capitalist systems, but predicting them is a complex task.

The Sahm rule attempts to predict recessions based on unemployment trends.

In the wake of the Great Depression, a Russian-American economist named Simon Kuznets popularized the formula for gross domestic product to summarize the health of the economy and provide the American government with a metric to track growth.

Economists define deflation as a sustained decline in prices across an economy

Deflationary periods are characterized by broad, significant price declines. The Federal Reserve can monitor deflation by tracking prices through price indexes, such as the Consumer Price Index (CPI), which characterizes the average costs for consumers each month.

When consumers think an economic downturn is looming, the 'lipstick index' economic theory argues that sales of more affordable luxury items (such as lipstick) go up.

In 2025, the US credit rating was downgraded over concerns about the debt-to-GDP ratio.

The Great Depression is one of history's most notable periods of deflation

The stock market crash of 1929 helped trigger a period of deflation in the United States by creating a drastic decrease in the total money supply. Because of the United States' central role in the world economy, virtually every single country was impacted by the recession.

Experts recommend preparing your finances accordingly if you're expecting to be laid off soon, taking actions such as looking into the cost of replacing employer-sponsored benefits like healthcare.

The Federal Reserve fought the Great Recession primarily with quantitative easing and repurchasing agreements.

A V-shaped recovery from a recession is the most common kind

When charted, recession recoveries resemble letters including V, U, W, L, and K. For instance, an L-shaped recovery involves a steep decline that slowly reverses.

The men’s underwear index predicts recessions based on men’s underwear sales

Internet users have been using some nontraditional indicators to predict whether a recession is imminent, including the return of so-called “recession pop.”

Gross domestic product only accounts for consumer spending, investments, government spending, and net exports—meaning factors such as stock market performance, Social Security payments, household labor, and the value of environmental damage largely aren't represented.

There are three different ways to calculate gross domestic product: the expenditure approach, the value-added approach, and the income approach.

Consumer spending accounts for 70% of America's gross domestic product.

Falling demand and lower costs of production cause deflation

"Falling demand" refers to anything that changes someone's willingness to spend money on goods and services. Global recessions, fears of a worldwide recession, and a fall in the money supply are all factors that could lead to falling demand. Likewise, lower production costs allow companies to increase production, which can lead to a surplus in supply.

An inverted yield curve has preceded every recession that’s occurred in the last 50 years

Prolonged yield curve inversions can predict recessions, but even brief inversions can cause investors to react with knee-jerk reactions.

Read about the evolution of the S&P 500 and its recession recovery

Since the S&P 500 is considered a bellwether index (meaning it represents the health of the US economy), its value is important for investors in both bull and bear markets. The S&P 500 has been impacted by recessions and downturns, from the 1970s oil crisis to the dot-com crash of the early 2000s.

The UK was already in a depression before the US Great Depression took hold

The US Great Depression was felt globally, but the severity and length of different countries’ economic downturns varied. For instance, Japan was the first country to exit its depression.

Experts don't believe upbeat tunes, called 'recession pop,' are legitimate recession indicators

Social media users have begun deeming pop music by the likes of Kesha and Katy Perry a "recession indicator" as they try to predict the next economic downturn.

Interest rates have historically been an indicator of the US economy's overall health.

The US Bureau of Labor Statistics releases a monthly 'jobs report' that tracks the unemployment rate, the number of Americans currently on payroll, and more.

'Good deflation' happens when prices naturally track with supply, meaning prices change gradually

This tends to make products and services more affordable and normalizes the standard of living. Bad deflation usually happens when there are sudden changes to either supply or demand. Near-zero [interest rates helped create the real estate bubble that sparked the Great Recession when it crashed](https://www.youtube.com/watch?v=LMo9mD8j7IA&t=91s) Because deflation distorts the value of money, deflation is particularly harmful for borrowers. Low interest rates made it easy for businesses and everyday people to take on enormous debt, which exacerbated the effects of the recession.

A list of the world's top 25 economies by GDP

Gross domestic product estimates the value of goods and services produced in a country, typically through the expenditure method, which adds up spending by consumers, investors and governments with the value of exports. The top five economies are the US, China, Germany, Japan and India.

Why there's a snack recession

Inflation and economic uncertainty have driven many Americans to make cuts to their snack budgets, according to reports from major food manufacturers like General Mills, JM Smucker, and Campbell's. Major retailers have also observed lower-income consumers cutting back on nonessentials due to the macroeconomic environment.

Some economists argue the national debt is not a critical concern

The US has the largest national debt and one of the highest debt-to-GDP ratios. These vitals have long been considered a sign of poor fiscal health, but economists are beginning to shift their attention to interest rates to evaluate national debt.

US state economies compared to entire countries

This map compares US state economies by their gross domestic product to that of a similarly sized country. For instance, California has the largest state economy in the US, with a GDP nearly equal to that of India, the fifth-largest economy in the world. Click here to see how the rest of the states compare.

The Great Depression was an international depression felt far beyond the US

Many countries suffered through a depression in the 1930s that the First World War, the US stock market crash, and an economic downturn in Germany turned into an international crisis.

Government shutdowns can cost the US economy billions

The Congressional Budget Office estimated that the 2018-19 shutdown reduced economic output by about $11B, including a permanent loss of roughly $3B

The US unemployment rate soared to over 24% during the Great Depression, the highest in recorded history.

Markets have always recovered and hit new highs following crashes

The crash that preceded the Great Depression was the most severe the US has ever experienced. It was 28 times worse than the downturn that followed the Cuban Missile Crisis.

COVID-19's shock to employment rates sparked some economists to fear deflation

COVID-19 simultaneously disrupted the supply chain and the labor market. Since the unemployment rate had hit record highs, some economists were worried that the supply chain would recover before the labor market. If that had happened, businesses would have been producing goods, but no one would have been able to buy them because they wouldn't have the disposable income to do so.

Watch Ray Dalio explain how the economy works

Dalio describes the economy as a machine that runs on three main cycles: productivity growth, the short-term debt cycle, and the long-term debt cycle. Dalio says layering these three cycles on top of each other essentially creates a template for understanding changes in the economy.

US homeownership rates declined from the start of the Great Recession through 2016.
