The headline unemployment number you see in the news — the one that rises and falls with economic cycles — tells only part of the story. The U6 unemployment rate is a broader measure that captures a wider range of labor market distress. Understanding what it includes, how it differs from the more familiar figures, and why economists and policymakers watch it helps put employment data in context.
The U.S. Bureau of Labor Statistics (BLS) publishes six different measures of labor underutilization, labeled U1 through U6. Each successive measure captures a broader segment of workers who aren't fully employed in the way they'd like to be.
U6 is the broadest of these measures. It includes:
The U3 rate — the one most often cited in news coverage — only counts people actively searching for work in the past four weeks. U6 is consistently higher than U3 because it casts a wider net.
The spread between U3 and U6 is itself an important signal. During healthy economic periods, the two rates move closer together. During recessions or slow recoveries, the gap widens — reflecting an increase in discouraged workers and involuntary part-time employment.
| Measure | What It Counts |
|---|---|
| U3 | Officially unemployed (active job seekers) |
| U4 | U3 + discouraged workers |
| U5 | U4 + other marginally attached workers |
| U6 | U5 + part-time for economic reasons |
Historically, U6 has run roughly 3 to 5 percentage points above U3 in normal labor market conditions, though the gap has been significantly wider during economic downturns. During the aftermath of the 2008–2009 financial crisis, U6 peaked near 17%, while U3 peaked around 10%. During the COVID-19 shock in April 2020, U6 reached roughly 22%.
The standard unemployment rate can understate labor market weakness in two important ways:
First, when workers become discouraged and stop actively searching, they drop out of the U3 calculation entirely — even though their circumstances haven't improved. A falling U3 rate can sometimes reflect people leaving the labor force rather than finding jobs.
Second, involuntary part-time employment — working 20 hours when you need 40 — represents real economic hardship that U3 doesn't capture. These workers are technically employed but aren't getting the hours or income they need.
U6 accounts for both. That's why labor economists often use U6 as a more complete picture of slack in the labor market.
The BLS derives U6 from the Current Population Survey (CPS), a monthly survey of roughly 60,000 households conducted by the Census Bureau. Respondents answer questions about their employment status, job search activity, availability to work, and hours worked. The data is collected monthly and published as part of the Employment Situation report, typically released on the first Friday of each month.
Because U6 is based on household survey data — not administrative records or unemployment insurance claims — it measures the entire labor force, including workers who never filed for benefits, self-employed individuals, and gig workers.
U6 is a macroeconomic measure. It describes aggregate conditions across the entire U.S. labor force. It doesn't:
The factors that determine whether someone qualifies for unemployment benefits — their work history, the reason they left their job, their state's specific rules — are entirely separate from how they might be classified in the U6 framework.
A worker counted in U6 is not necessarily receiving unemployment insurance, and many aren't. Unemployment insurance is a state-administered program funded through employer payroll taxes. Eligibility depends on meeting each state's specific wage and hour thresholds during a base period, the reason for job separation, and ongoing availability and work search requirements.
Many workers captured in U6 — discouraged workers, marginally attached workers, involuntary part-timers — may not qualify for benefits under their state's rules, or may have exhausted their benefits, or may never have filed. The BLS survey measures labor market conditions independent of who is receiving benefits.
U6 figures fluctuate based on broader economic forces, but within those aggregate numbers, individual circumstances vary enormously:
The national U6 figure tells you something important about overall labor market health. What it can't tell you is how conditions in your specific region, industry, or personal situation compare to that national picture — and it says nothing at all about what any individual's unemployment claim might look like.
