Is rising education driving down structural unemployment?
Core argument: The U.S. trend unemployment rate fell 3.3 percentage points—from 7.8% in 1976 to 4.8% in 2024—with rising educational attainment alone accounting for 1.0 percentage point of that structural decline.
We find that the trend unemployment rate declined from 7.8% in 1976 to 4.8% in 2024 [Figure 1]. Roughly half of that decline reflects compositional change. Figure 2 separates the estimated cumulative change in the annual unemployment trend since 1976 into its components. The total decline was about 3.3 percentage points by 2024. Changes in workforce composition account for a little more than half of that decline. Rising educational attainment is the single largest compositional force, lowering the trend about 1pp. Figure 4 plots estimated education shares for entering cohorts of women, and these patterns are similar for male cohorts (not shown). The figure shows a steady long-run fall in the share of new female cohorts with less than high school education and a steady rise in the share with some college or a college degree. [Returning to Figure 2], changes in group-specific LFP rate trends contribute only ~0.3 pp. The remaining decline, a bit under 1pp, comes from lower group-specific trend unemployment.
