U-6 Underemployment Rate

The BLS publishes six different measures of unemployment, labeled U-1 through U-6. The headline Unemployment Rate, U-3, counts only those who are actively looking for work. The broadest measure, U-6, adds workers who want a job but haven't searched recently, workers only marginally attached to the labor force, and workers part-time for economic reasons. The May 2026 reading is 8.1%.

The gap between U-3 and U-6 is a rough index of hidden slack. The current spread sits well above the 2022 reading of roughly 3.1 points and well below the 2009 crisis gap that exceeded 7 points. That gap rises when underemployment climbs faster than unemployment, which is what American Worker Index-adjacent labor distress typically looks like in its early stages.

U-6 leads U-3 modestly when the labor market turns, because underemployment builds before outright job loss. Initial Unemployment Claims validates 1 quarter with r = 0.72 into U-6 itself across two prior crises — meaning when first-time filings rise, underemployment follows.

For households, U-6 is often the more honest number. A worker who has stopped looking because the market is dead or who is stuck in 25 hours a week isn't counted in the headline figure. They are counted here. If the question is how many Americans are not getting the work they need, 8.1% is closer to the truth than the headline U-3 print.
