The BLS’ alternative measures of labor underutilization each capture a progressively broader slice of labor market weakness. These measures shed light on Americans who have fallen out of the labor market or stepped back from searching and therefore are not counted in the headline unemployment number (U-3), meaning the historically low U-3 rate understates how many people are struggling to connect with work.
Headline unemployment understates the true extent of labor market slack
Across all measures of underutilization, labor market conditions today remain worse than pre-pandemic norms. As of May 2026, the broadest measure of labor underutilization, the U-6 unemployment rate, stands at 8.1 percent, significantly higher than U-3 headline unemployment, at 4.3 percent. While the U-3 three-month average rate has grown faster than the U-6 compared with pre-pandemic averages, the U-6—which includes the unemployed, broader measures of detachment from the labor market, and underemployment measured by involuntary part-time work—has been sitting more than 1 percentage point above where it was just a few years ago.
As of May 2026, the three-month average rate of U-3 unemployment is 13.7 percent above its 2018–2019 average. (see Figure 2) Meanwhile, the three-month average U-4 rate, which captures both unemployed and discouraged Americans, sits 13.6 percent above its pre-pandemic average. Similarly, the three-month average U-5 rate—which includes unemployed, discouraged, and all other marginally attached Americans who have stopped searching entirely—is running 14.4 percent above baseline, indicating that the rise in headline unemployment is partly understated because of this parallel rise in labor force detachment. U-6 unemployment, often referred to as the “real unemployment” rate, sits 8.9 percent above its pre-pandemic average, highlighting that more Americans who have managed to stay in the labor market are settling for involuntary part-time work.
