No Widespread Displacement, but the AI Employment Gap for Young Workers Has Widened to 19%
Highlights from the new revision of “Canaries in the Coal Mine? Six Facts About the Recent Employment Effects of Artificial Intelligence”
by Erik Brynjolfsson, Bharat Chandar, and Ruyu Chen
We are releasing a revised version of “Canaries in the Coal Mine? Six Facts About the Recent Employment Effects of Artificial Intelligence.” Using payroll data from ADP, we document six facts about how employment has evolved since the release of ChatGPT, with particular attention to differences by age and AI exposure.
The updated data strengthen several patterns we first documented in August 2025. Most notably, the employment gap for young workers in highly AI-exposed occupations has continued to widen through mid-2026.
Our six main facts
- We do not see widespread, economy-wide job displacement associated with AI.
- However, young workers in AI-exposed occupations are increasingly falling behind their less-exposed peers. Employment among workers ages 22–25 in highly AI-exposed occupations now stands about 19% below where it would be if it had kept pace with employment among similarly aged workers in less-exposed occupations. Experienced workers show no comparable gap.1
- This divergence has widened steadily since we first documented it in August 2025: by this same measure, the shortfall was 15% at the July 2025 data vintage and is 19% as of June 2026.
- The adjustment appears to operate primarily through reduced hiring of young workers rather than increased separations.
- The declines are concentrated in occupations where AI usage tends to automate human tasks. In occupations where AI is used more to complement workers, employment is flat or rising, particularly among more experienced workers.
- So far, adjustment is showing up primarily in employment rather than base pay.2
These are descriptive patterns, not causal estimates of the effect of AI. The timing and structure of the changes are suggestive, but the data alone cannot establish how much of the divergence was caused by generative AI rather than other forces affecting the labor market.
What is new in this revision
Beyond extending the data through mid-2026, the revised paper provides new evidence about the mechanisms that may be driving these patterns.
One distinction that appears important is between codified and tacit knowledge.
Employment has declined among young workers in occupations that rely heavily on codified knowledge: formal, standardized, documented knowledge that can be taught through education, textbooks, or written procedures. In contrast, employment has increased among experienced workers in occupations that rely more heavily on tacit knowledge acquired through practice, mentorship, and repeated exposure to real situations.
This distinction is consistent with a world in which generative AI is particularly effective at reproducing and applying knowledge that has already been encoded in text and other digital information, while experience-based knowledge remains harder to replicate.
We also find that women face greater AI exposure on average, an important source of heterogeneity that we intend to monitor as the data evolve.
Is AI causing these changes?
We cannot yet answer that question definitively.
Several prominent alternative explanations do not appear sufficient to account for the pattern. The divergence remains when we exclude technology firms and computer occupations, when we control for exposure to interest-rate increases and remote work, when we include firms that enter or leave the sample, and when we use alternative measures of AI exposure.
There are also several reasons to think AI may be playing a meaningful role:
- The divergence has continued to widen through mid-2026, well after interest rates peaked.
- By November 2022, the relative position of exposed young workers had already returned to roughly its pre-pandemic level. The subsequent decline therefore pushes the gap below that earlier baseline rather than merely reversing a pandemic-era distortion.
- The declines are concentrated specifically in occupations where observed AI usage is more automating than complementary, and they show a clear age gradient. That combination is not naturally predicted by explanations based solely on interest rates, education, or remote work.
- U.S. government administrative data show broadly consistent raw descriptive patterns by age and industry (Tucker 2026, U.S. Census Bureau).
At the same time, there are important reasons for caution.
The gaps between more- and less-exposed young workers shrink when we account for education. Some differential trends are visible before the widespread use of generative AI. The estimated gaps are also larger in the ADP analysis sample than in national survey benchmarks.3
In addition, improvements to our data pipeline produced qualitatively similar raw patterns, but estimates that account for overall changes in firm hiring are directionally consistent while becoming more sensitive to specification choices. This raises legitimate questions both about how much of the pattern is actually caused by AI and about how well the results in the ADP analysis sample generalize to the broader economy.
For those reasons, we do not view this paper—or any single study—as definitive evidence of AI’s labor-market effects. A growing body of research has appeared since the first version of our paper, and the cumulative evidence across studies will ultimately be more informative than any one result.
What comes next
We do not know whether the patterns documented here will accelerate, stabilize, or reverse.
That uncertainty is one reason we have invested in building the infrastructure to measure these changes continuously rather than relying on occasional snapshots.
The Stanford Digital Economy Lab recently launched the AI Economic Indicators, providing high-frequency measures of how AI is changing the economy. As part of that effort, our Canaries Dashboard will update the key results in this paper every month.
The goal is not to declare the labor-market effects of AI settled. It is to make them measurable.
If generative AI is beginning to reshape opportunities for particular groups of workers before its effects are visible in aggregate employment statistics, we want to identify those changes early, understand the mechanisms behind them, and track whether they spread.
That is, after all, what canaries are for.

Footnotes
- In levels, employment of workers ages 22–25 in the two most exposed quintiles fell about 11% between November 2022 and June 2026, while employment of the same age group in the three least-exposed quintiles grew about 10%.
- Base pay excludes bonuses, equity, and other variable pay.
- The discrepancy between the estimates is concentrated in education, health care, and public administration, and part of it reflects recent Census Bureau revisions to the ACS population weights.

Postdoctoral Fellow
Bharat Chandar is a labor economist working on understanding AI’s impact on work. His recent projects include work with Erik Brynjolfsson and Ruyu Chen tracking “canaries in the coal mine” for entry-level employment changes in jobs exposed to AI. He also recently surveyed the state of knowledge about AI and labor markets.
His ongoing work has focused on three areas. The first asks, how will workers adjust if we see AI-driven changes in hiring? Which workers will have an easier or more challenging time if displaced, and where should we target support? The second asks, how can we use AI to make it easier for people to learn new things and pursue new forms of work? Third, how will impacts of AI differ across the world?
