What the sources establish

ADP reported a September 2026 year-over-year 3.7% employment decline for US ages 22–25 in highly AI-exposed occupations, versus a 0.2% increase in least-exposed jobs.

Evidence limit: Observational payroll trends do not prove AI caused the decline; exposure differs from measured displacement.
