Methodology
Careers are scored on five normalized axes — salary, job growth, AI resilience, education barrier, and competition — each on a 0–100 scale, with composite Future-Proof, ROI, and breadth verdicts.
See the full methodology and weights →Confidence notes
- Salary and growth figures come from federal Bureau of Labor Statistics data — administrative wage records and official projections, not surveys.
- AI-resilience scores are computed from O*NET task and work-context data, applied consistently across every occupation.
- Every measure is normalized to a fixed 0–100 scale, so careers are directly comparable.
Limitations
- BLS wage data reflect national medians; actual pay varies widely by region, employer, and experience.
- Job growth is a 2023–2033 projection, not a guarantee — labor markets shift with technology and the economy.
- AI-resilience is a directional estimate of automation exposure, not a prediction that any role will or will not be automated.
- Pipeline and compensation-by-company-size figures are modeled estimates, not measured outcomes.
