The U.S. trend unemployment rate has dropped from 7.8% in 1976 to 4.8% in 2024, a decline driven in roughly equal parts by a more educated and older workforce and by newer generations entering the job market with lower jobless rates, according to new research published by the Federal Reserve Bank of San Francisco in August 2026. The study, authored by Andreas Hornstein and Marianna Kudlyak, examined five decades of labor market data across 44 demographic groups to separate long-term structural shifts from cyclical business fluctuations. The findings show that demographic transformation and generational change have fundamentally reshaped America's baseline unemployment picture.
Rising educational achievement stands out as the single biggest force pushing joblessness down, accounting for about 1.1 percentage points of the total 3.3-point decline since the late 1970s. The aging of the workforce contributed roughly another 0.7 percentage point to the drop. Among prime-age adults between 25 and 54, the share holding more than a high school education jumped from 21.0% in 1976–1984 to 31.9% in 2016–2024, while those with a high school diploma or less fell from 29.8% to 16.8%. For workers 55 and older, the college-educated share soared from just 6.0% to 21.3% over the same periods. The population itself has shifted older: people 55 and up rose from 27.3% of the workforce in the earlier period to 36.6% in the later one, while the 16-to-24 age group shrank from 22.0% to 14.7%. Because older and more-educated workers traditionally face lower unemployment, these compositional changes alone pushed the trend rate down even before accounting for within-group improvements.
The other half of the decline—just under 1 percentage point—comes from lower unemployment propensities within demographic groups themselves, meaning a worker with identical age, gender, and education faces less joblessness today than decades ago. The report finds that newer cohorts appear to bring somewhat lower unemployment risk into the labor market, with men's trend unemployment beginning to edge down in the early 1990s and women's declining more clearly around 2000. For entering cohorts of women age 25, the college share climbed from less than 10% to roughly 50% for recent cohorts, while for men the share with less than high school education fell from around 70% for those born in the late 1920s to single digits today.
The structural forces behind the decline show no sign of reversing. Hornstein and Kudlyak project that continued demographic shifts will push the trend unemployment rate down another 0.4 percentage point over the next two decades, reaching about 4.4% by 2044. Aging will continue to lower overall unemployment because older workers who stay in the labor force tend to face lower jobless rates, even as the same aging process reduces overall participation since older people work less. Educational upgrading will keep pulling in the same direction as the labor force tilts further away from younger, high-unemployment groups toward older, more-educated workers with historically steadier employment. The report's central message is clear: what looks like a cyclical unemployment number today sits atop a falling structural floor that has dropped 3 percentage points in half a century and isn't done moving yet.
