Claim LD02-HQ-C04 (v1.0)

By June 2026, US workers aged 22–25 in highly AI-exposed occupations were about 19% below the employment path of similarly aged workers in less-exposed occupations, with the divergence driven mainly by reduced hiring rather than separations.

Research opportunities this claim motivates

What this claim leaves open for research. Each is a hypothesis about a gap, not a finding.

Why do Nordic registers and US data disagree about young workers in AI-exposed jobs?The US payroll evidence shows a 19% employment gap for 22–25-year-olds in highly exposed occupations, driven mainly by hiring; the claim itself does not license reading this as a causal AI effect, which is why the cross-country contrast is informative.
Does the young-worker hiring gap hold up with survey-measured AI use instead of exposure?The 19% gap for 22–25-year-olds is defined by exposure and is not licensed as a causal AI effect; re-ranking occupations by measured use is one way to probe it.
