> The first figure in a release is often revised. US GDP is revised in later estimates, and payroll numbers can change in later months. Here is what that means when you read a headline.

Many economic figures are published more than once. A quarter's GDP is followed by later estimates, and the numbers can change at each step. The Bureau of Economic Analysis lists the second estimate separately in its schedule, for example as "GDP (Second Estimate) and Corporate Profits, 3rd Quarter 2026" ([Bureau of Economic Analysis release schedule](https://www.bea.gov/news/schedule)).

## What revisions look like on this site

- **GDP**: [US GDP growth is revised up to 2.2% for the second quarter](/news/us-gdp-second-quarter-2026-third-estimate/) shows a later estimate changing an earlier figure.
- **Payrolls**: [US employers add just 29,000 jobs in September, and July's payrolls are revised](/news/us-jobs-report-september-2026-payrolls/) shows earlier months changing when a new month is published.
- **UK GDP**: [UK GDP growth is revised up to 0.5% for the second quarter](/news/uk-gdp-second-quarter-2026-revised/) is an example from another economy.

## How to read a headline

When you see a figure in a release, check whether it is the first estimate, a revised estimate, or the same figure as the previous month. Revisions do not mean the first number was wrong. They mean more source data arrived. For the calendar terms used in releases, see [How to read an economic calendar](/news/how-to-read-an-economic-calendar/).

## Common questions

### Why does GDP get revised?

Later estimates use more complete source data, so the figure can change between the advance, second and third estimates.
