The US unemployment rate
A rate built from a survey of sixty thousand households, published to one decimal place - and the sampling error is wider than the step markets trade on.
At a glance
- Published by
- US Bureau of Labor Statistics, monthly
- Released
- Usually the first Friday at 8:30am ET, alongside payrolls
- The number markets trade
- The U-3 rate, seasonally adjusted, to one decimal
- Revisions
- The rate itself carries no monthly revision; seasonal factors and population controls change each January
What the number actually counts
The unemployment rate is a ratio, and both halves of it surprise people. The numerator counts those without a job who were available for work and actively looked for one in the previous four weeks. The denominator is the labour force: everyone employed plus everyone unemployed by that definition. People who want a job but stopped looking appear in neither half.
That is why the rate can fall in a bad month and rise in a good one. If discouraged workers give up searching, they leave the labour force, the numerator and denominator both shrink, and the rate improves. If a strong economy pulls people off the sidelines faster than firms hire them, the rate rises while employment grows.
The headline figure is one of six measures the same release publishes. U-3 is the headline. U-6 adds those working part time because they cannot find full-time work and those marginally attached to the labour force, and it runs roughly four to five percentage points higher. When a market question says unemployment without a qualifier, it almost always means U-3, seasonally adjusted - but that is worth confirming rather than assuming.
Employment and unemployment are not opposites. Both can rise in the same month, and regularly do.
Who acts on it
The Federal Reserve has a dual mandate, and this is the number that carries half of it. Price stability has CPI and PCE; maximum employment has this rate. In practice the committee reads it alongside payrolls, wage growth and the participation rate, but the unemployment rate is the one that appears in the statement language and in the quarterly projections.
It also drives policy that has nothing to do with monetary policy. Extended unemployment insurance benefits trigger off state-level rates, federal funding formulas reference them, and the recession dating committee at the NBER treats a sustained rise as one input among several. The Sahm rule - a widely watched rule of thumb, not an official indicator - flags a recession when the three-month average rises half a point above its low of the previous year.

Who publishes it, and how it is built
The rate comes from the Current Population Survey, a monthly survey of about sixty thousand households run by the Census Bureau for the Bureau of Labor Statistics. It is a different instrument from the payrolls number in the same release, which comes from a survey of employers. One counts people, the other counts jobs, and a person holding two jobs shows up twice in one and once in the other.
The reference period is the calendar week containing the twelfth of the month. Anything that happens after that week - a mass layoff on the twentieth, a hiring wave at month end - belongs to the next report, no matter what the news cycle says.
The survey size sets the precision, and the precision is coarser than the reporting. The BLS itself states that a change in the rate of about two tenths of a percentage point is required before it can be called statistically significant at the ninety percent level. The published figure carries one decimal place. A market question about a single tenth is therefore, in part, a question about sampling noise.
- About 60,000 households surveyed each month; roughly a quarter rotate out every month.
- The reference week contains the twelfth; the release lands early the following month.
- Each January the series absorbs updated population controls, which can shift levels without any change in the labour market.
- Six measures, U-1 through U-6, ship in the same release. U-3 is the headline.
| Name | Share |
|---|---|
| Job losers and completed temporary jobsThe cyclical part - this is what rises in a downturn | 51share of unemployed |
| Re-entrants to the labour forceReturning after time away; rises when conditions look good | 27share of unemployed |
| New entrantsMostly younger workers looking for a first job | 12share of unemployed |
| Job leaversQuit voluntarily; a confidence signal, not a distress one | 10share of unemployed |

What moves a monthly print
The six forces that decide whether the rate ticks up or down - starting with the one that moves it without a single job being lost.
Where an unemployment view gets traded
There is no exchange for the rate itself - four instruments carry the view instead, and only two of them settle on the published number.
How the number travels through markets
The chain from an 8:30am release to a repriced rate path, and why the household survey moves markets less than the jobs number printed beside it.
How this shows up in prediction markets
Which decimal settles the market, why a single tenth is inside the noise band, and the four checks worth running before taking a side.

Frequently asked questions
- Why can the unemployment rate rise while the economy adds jobs?
- Because the two numbers come from different surveys and the rate has a denominator. If people re-enter the labour force faster than firms hire them, employment and the rate both rise. It happens regularly and is not a contradiction.
- What is the difference between U-3 and U-6?
- U-3 is the headline rate: people without work who searched in the last four weeks. U-6 adds those working part time because they cannot find full-time work, plus people marginally attached to the labour force. U-6 typically runs four to five percentage points higher.
- Is a one-tenth move in the rate meaningful?
- By the agency's own standard, not on its own. The BLS states that a change of about two tenths of a percentage point is needed for statistical significance at the ninety percent level. That is why the direction over three months tells you more than any single print.
- Does the unemployment rate get revised?
- Not month by month, the way payrolls are. What changes is the seasonal adjustment, revised annually, and the population controls introduced each January, which can shift the level without any change in the labour market itself.
