Gross Domestic Product (GDP)

What GDP measures

Gross domestic product (GDP) is the value of the final goods and services produced in the United States. It is the broadest single measure of the size and growth of the economy. “Final” means it counts what is sold to end users, so the steel in a car is not counted separately from the car.

The headline figure is real GDP growth: the change in output after removing the effect of price changes. BEA reports quarterly growth as a seasonally adjusted annual rate, meaning the quarter’s change is expressed as what it would be if that pace continued for a full year. A quarterly change of about half a percent therefore appears as roughly 2 percent annualised. This convention differs from many other countries, which report plain quarter-over-quarter changes, and is a frequent source of confusion.

Who publishes it and when

The U.S. Bureau of Economic Analysis (BEA) publishes GDP at 8:30 AM Eastern Time. Each quarter gets three successive estimates:

• Advance estimate: about one month after the quarter ends. This is the first look and usually the biggest market event.
• Second estimate: about a month later, with more complete data.
• Third estimate: about a month after that.

BEA also conducts periodic broader updates that can revise several years of history. The release schedule and data are on BEA’s GDP page.

Why the advance estimate is incomplete

The advance estimate is published before all the source data are in. For some components, data for the full quarter are not yet available, and BEA fills the gaps with assumptions, which it documents in a key source data table published with the release. Each later estimate replaces assumptions with fuller data, and the new release supersedes the previous one.

The numbers traders watch

GDP is built from four broad types of spending:

• Consumer spending (personal consumption expenditures), the largest component.
• Business investment in equipment, structures and intellectual property, plus residential investment and inventories.
• Government spending on goods and services.
• Net exports: exports minus imports. Imports are subtracted because they are produced abroad.

Some components swing a lot from quarter to quarter without saying much about the underlying economy. Inventories and net exports are the usual suspects. For that reason, analysts often look at real final sales to private domestic purchasers, which BEA reports as consumer spending plus private fixed investment. It strips out inventories, trade and government to give a steadier read on private demand.

The release also includes price measures. The PCE price index and core PCE price index for the quarter appear in the GDP report, though the monthly PCE report gets more attention for inflation.

Real versus nominal

Nominal (current-dollar) GDP is measured at today’s prices. Real GDP adjusts for inflation. When people discuss growth, they almost always mean real GDP.

GDP versus GDI

BEA also estimates gross domestic income (GDI), which measures the economy from the income side: wages, profits and other income earned in production. In principle the two should match; in practice they differ, and the gap between them is called the statistical discrepancy. Some analysts average the two for a fuller picture.

How markets commonly react

GDP often moves markets less than you might expect, because it is backward-looking: by the time the advance estimate arrives, monthly reports on retail sales, trade and inventories have already given forecasters a good idea of the number. The bigger reactions tend to come when the details surprise, such as consumer spending far from expectations or a notable change in the quarterly inflation measures. Strong growth can be read as supportive for stocks or as a reason for higher interest rates, depending on whether the market is more worried about recession or inflation. No pattern is dependable.

Common misreadings

• Forgetting the annualised rate. The headline is an annual pace, not the quarter’s actual change.
• Calling a recession from two negative quarters. That is a popular rule of thumb, not the official definition. Recessions in the U.S. are dated by a committee of the National Bureau of Economic Research using a broader set of indicators.
• Taking the advance estimate as final. It is the least complete of the three estimates and is routinely revised.
• Over-reading inventories and trade. These can swing the headline without much change in underlying demand.

Frequently asked questions

What time is the GDP report released?

At 8:30 AM Eastern Time on the scheduled release date.

What is the difference between the advance, second and third GDP estimates?

They are successive estimates of the same quarter, each using more complete source data. The advance estimate comes about a month after the quarter ends; the second and third follow at roughly monthly intervals.

Why is GDP shown as an annual rate?

BEA expresses each quarter’s change as the pace it would represent over a full year. That makes quarters easier to compare with annual figures but makes the numbers look larger than the actual quarterly change.

Does a negative GDP quarter mean a recession?

Not by itself. Two negative quarters is a common shorthand, but U.S. recessions are officially determined by the NBER’s dating committee using many indicators.
