Who Declares a Recession? How the NBER Defines and Dates U.S. Business Cycles

The economic recession definition used in the United States comes from the National Bureau of Economic Research, whose Business Cycle Dating Committee identifies recessions as a significant decline in economic activity spread across the economy and lasting more than a few months. The committee dates recessions after the fact, using several monthly indicators rather than a single GDP rule.

Key Takeaways

  • The NBER’s Business Cycle Dating Committee maintains the official chronology of U.S. business cycle peaks and troughs.
  • The NBER defines a recession as a significant decline in economic activity, spread across the economy, that lasts more than a few months.
  • The popular “two consecutive quarters of falling GDP” rule is not the NBER’s definition.
  • In recent decades, the committee has relied most heavily on real personal income less transfers and nonfarm payroll employment.
  • According to the NBER chronology, the most recent recession ran from a February 2020 peak to an April 2020 trough.
  • The committee typically announces peaks and troughs months after they occur, to avoid major revisions.

The Official Economic Recession Definition Comes From the NBER

When people ask what a recession is, the answer that carries official weight in the U.S. comes from the National Bureau of Economic Research. Its Business Cycle Dating Committee maintains a chronology of U.S. business cycles, identifying the months when economic activity peaked and bottomed out.

The NBER’s definition emphasizes that a recession involves a significant decline in economic activity that is spread across the economy and lasts more than a few months. Each part of that definition matters, and the committee treats them as a set rather than a checklist.

Depth, Diffusion and Duration

The committee describes three criteria: depth, diffusion and duration. It treats them as somewhat interchangeable. Each must be met to some degree, but extreme conditions on one can partially offset weaker signals from another.

The 2020 downturn shows how that works. For the February 2020 peak, the committee concluded that the drop in activity was so large and so widespread that, even if it proved brief, the downturn should be classified as a recession.

Why Two Quarters of Negative GDP Is Not the Official Rule

The financial press often defines a recession as two consecutive quarters of decline in real GDP, a shorthand frequently called a “technical recession.” The NBER has said its procedure differs from that rule in a number of ways.

One key difference is depth. The NBER’s definition includes the phrase “a significant decline in activity,” so the size of a downturn matters, not just its direction. The committee also leans on monthly data rather than quarterly figures, which allows it to date turning points more precisely. The NBER further describes a recession as a period of diminishing activity rather than diminished activity, a distinction that separates the decline itself from the low point it leads to.

The Recession Indicators the NBER Watches

Because a recession must affect the economy broadly rather than a single sector, the committee focuses on economy-wide measures published by federal statistical agencies. These include real personal income less transfers, nonfarm payroll employment, employment measured by the household survey, real personal consumption expenditures, real manufacturing and trade sales, and industrial production.

There is no fixed formula for how those measures are weighted. In recent decades, the committee has relied most heavily on two: real personal income less transfers and nonfarm payroll employment. For quarterly dating, it also weighs both the expenditure-side and income-side estimates of real GDP, which are not available monthly.

Peaks, Troughs and the Business Cycle

The NBER’s chronology divides the economy into two phases. Expansions run from a trough to a peak, and recessions run from a peak to a trough. By convention, the peak month is the last month of an expansion, and the trough month is the last month of a recession.

Why Recession Announcements Come Months Later

The committee’s approach is retrospective by design. It waits until enough data are available to avoid major revisions to its chronology, and it does not declare a peak until it is confident a recession has occurred. As a result, peaks are typically identified a number of months after they actually happened, and troughs are announced only once the committee is confident an expansion is underway.

That lag explains why recession debates often play out in real time before any official call. By the time the committee announces a turning point, the economy may already have moved past it.

How Long Recessions Last

The NBER describes expansion as the normal state of the economy and notes that most recessions are brief. The most recent recession, running from a February 2020 peak to an April 2020 trough, illustrates how short a recession can be. The NBER adds an important caveat: the time it takes for the economy to return to its previous peak level of activity can be much longer than the recession itself.

FAQs

What is the economic recession definition?

In the U.S., 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. Its committee weighs depth, diffusion and duration together.

Who declares a recession in the United States?

The National Bureau of Economic Research’s Business Cycle Dating Committee determines the official peak and trough dates of U.S. business cycles. It announces those dates retrospectively, often months after they occur.

What is a technical recession?

A technical recession is a common shorthand for two consecutive quarters of declining real GDP. It is not the NBER’s official definition, which considers a broader set of monthly indicators and the depth of a decline.

What indicators does the NBER use to identify a recession?

The committee looks at measures including real personal income less transfers, nonfarm payroll employment, household-survey employment, real consumer spending, real manufacturing and trade sales, and industrial production. In recent decades, it has relied most heavily on income less transfers and payroll employment.

When was the last recession in the U.S.?

According to the NBER chronology, the most recent recession began after a February 2020 peak and ended with an April 2020 trough.

Winter, The Season for a Facial Refresh

By Jeremy Murphy

When the temperatures drop and the days get shorter, there is one unexpected upside. For patients considering a facelift or laser treatment, the colder months offer a practical advantage that has little to do with the temperature itself and everything to do with the sun.

A Shining Ray in the Darker Months

According to Dr. Luis Macias, the Los Angeles-based plastic surgeon known for his sophisticated, natural approach to facial rejuvenation, reduced sun exposure makes winter particularly appealing for certain procedures. That matters because many of today’s laser treatments are light-sensitive, including IPL and BBL treatments, as well as erbium and CO2 lasers. Patients need to limit sun exposure during the healing process, making winter an easier season in which to schedule treatments.

“In the winter, you’re less likely to have those competing activities,” he says. “I think the winter months are a good time for people to do some of these refreshes for themselves.”

It is not, Macias emphasizes, that cold weather magically produces better surgical results. There is no special wintertime advantage when it comes to blood vessels, healing, or the ultimate outcome of a facelift. The benefit is largely practical: less intense sun exposure and, for many people, fewer beach days, vacations, and outdoor activities to work around.

What to Do

The technology itself, meanwhile, has become considerably more sophisticated. Macias stresses that there is no single “best” laser. The appropriate treatment depends on what a patient actually wants to address.

Some technologies are particularly effective for pigmentation and redness. BBL, or broadband light, can target those concerns while also helping to thicken the dermis. But if the goal is resurfacing, fine lines or wrinkles, a different approach may be necessary.

That is where fractional lasers such as erbium and CO2 come in. Macias compares the evolution of these treatments to maintaining a lawn. An ablative CO2 laser essentially “mows the lawn,” removing more of the surface, while fractional treatment “aerates” it by creating tiny channels that allow the skin to heal more quickly.

For some patients, however, CO2 can create pigmentation concerns. Erbium lasers, Macias says, can offer greater versatility, particularly for patients with darker skin tones, while still allowing surgeons to control the degree of coagulation and resurfacing.

A Refreshed Look

The same philosophy of restraint is increasingly influencing the facelift itself.

The era of the conspicuously “done” face is fading. Macias says he is seeing more patients seeking a refreshed appearance rather than an obviously altered one. Deep-plane facelifts, which address deeper anatomical structures rather than simply tightening the skin, have become an important part of that evolution.

The trend is also moving younger.

Rather than waiting until significant skin laxity develops, patients are increasingly addressing early signs of aging. The objective is subtle enough that friends and family may simply think someone looks rested, healthy, or particularly good after a vacation. “If you go from turkey neck to no turkey neck, it’s very obvious,” Macias says. “People don’t want that.”

Normalizing Cosmetic Work for Men

That desire for subtlety is also bringing more men into the conversation. Macias says he is seeing significantly more male patients interested in facial rejuvenation, although preserving a masculine appearance remains paramount.

Many men, he says, arrive with examples of celebrities whose work they like precisely because they cannot tell surgery was performed. Some of his male patients have even allowed him to share their before-and-after photographs, something he says can be particularly powerful in overcoming the stigma surrounding cosmetic surgery for men.

“They allow other guys to look and go, ‘Oh yeah, I could do that,’” he says. “That guy looks pretty good. He still looks like himself.”

Precision and Tailoring

And then there is the changing attitude toward fillers. Hyaluronic acid fillers have taken a beating on social media, Macias says, largely because they became so ubiquitous and were sometimes used indiscriminately. The problem, in his view, was not necessarily the material itself but the way it was being used. “There’s still some role for hyaluronic acid done by a trained professional that knows where to put it, knows what to put where, at what depth,” he says.

At the same time, patients are increasingly interested in alternatives, including biostimulatory and regenerative treatments. Sculptra has benefited from that shift, while products such as Renuva, derived from donated human adipose tissue, are also attracting renewed attention.

Another newer technology gaining momentum is Quantum, a bipolar radio-frequency device designed to tighten skin while addressing some underlying fat. Macias sees it as part of a broader movement toward treatments that work beneath the surface rather than simply adding volume.

Ultimately, the biggest change is philosophical. Patients are no longer necessarily looking for a dramatic transformation. They want to look like themselves, only fresher. And winter, with its shorter days and reduced UV exposure, may be the perfect time to start.
