U-3, U-6 and the rest of the jobs report
The US unemployment rate everyone quotes is one of six official measures, and it excludes people who want work but stopped looking. In some cycles the measures it excludes tell the more important story.

How each one is built
- Unemployment rate (U-3)
- Method: Unemployed as a share of the labour force; requires active job search in the last four weeks
- Covers: The headline rate, from the household survey
- Released: First Friday
- Broad unemployment (U-6)
- Method: U-3 plus discouraged and marginally attached workers plus part-time for economic reasons
- Covers: The widest official measure of underused labour
- Released: With the jobs report
- Labour force participation rate
- Method: Share of the population aged 16+ working or actively looking
- Covers: Falls when people give up looking, which mechanically lowers U-3
- Released: With the jobs report
- Employment-population ratio
- Method: Share of the population that is employed — no search test at all
- Covers: Immune to the discouraged-worker problem
- Released: With the jobs report
- Initial jobless claims
- Method: Administrative count of new unemployment insurance filings
- Covers: A flow of new job losses, weeks ahead of the monthly rate
- Released: Thursday
Why the headline rate can fall for a bad reason
U-3 counts you as unemployed only if you actively looked for work in the past four weeks. Stop looking and you leave the labour force entirely — which lowers both the numerator and the denominator, and pushes the unemployment rate DOWN. A falling U-3 alongside a falling participation rate is a warning sign, not good news.
The employment-population ratio has no search test, so it cannot be gamed this way. It is the cleanest single measure of how much of the population is actually working, though it drifts down over decades as the population ages.
Which one to use
Use U-3 for comparison across countries and across history — it is the standard international definition and has the longest consistent series.
Use U-6 when the question is labour market slack. The gap between U-6 and U-3 widens in a weak recovery, when people are working part time because full-time work is unavailable, and that gap has historically closed late in an expansion.
Use prime-age employment-population (25–54) to strip out demographics, and initial claims for timing: they are weekly and move before any monthly measure.
Frequently asked questions
- What is the difference between U-3 and U-6?
- U-3 counts only people who actively looked for work in the last four weeks. U-6 adds discouraged and marginally attached workers plus those working part time because they cannot find full-time work.
- Can the unemployment rate fall for a bad reason?
- Yes. When people stop looking for work they leave the labour force, which lowers the measured unemployment rate even though nobody found a job.
- Why is the prime-age employment rate often preferred?
- Restricting to ages 25 to 54 removes the effect of students and retirements, so changes reflect labour market conditions rather than demographics.
- Which labour measure arrives first?
- Initial jobless claims, published every Thursday for the week ending the previous Saturday, weeks ahead of the monthly household survey.
