The source ledger

Every figure displayed on this site, with its primary source, its retrieval date, and — for computed results — the method. This page exists so you can check us. Paid reports re-derive their figures on the order date and carry this same ledger for their own numbers.

1 · The engine finding (r = 0.907; 122 of 192)

Claim displayed: across 782 scoreable occupations, the correlation between an occupation’s AI-exposure percentile and the mean exposure percentile of its ~20 skills-related occupations is r = 0.907; of the 192 top-quartile-exposed occupations, 122 (63.5%) have zero related occupations below median exposure, and on average only 6.4% of their related occupations sit below median.

Derived: 2026-08-15, from files downloaded that day from the primary publishers.

O*NET 30.3 Database — “Related Occupations” (18,460 pairs, 923 occupations), “Occupation Data,” “Job Zones.” U.S. Department of Labor / Employment and Training Administration, CC BY 4.0.
Felten–Raj–Seamans AI Occupational Exposure (AIOE) appendix — 774 occupations scored, SOC-2010 vintage (published 2021).

Method, stated fully: AIOE scores are converted to percentile ranks (average-rank method) across the 774 scored occupations. O*NET-SOC 2019 codes are joined to AIOE’s SOC-2010 codes on the 6-digit base code. An occupation is “scoreable” when it has an AIOE percentile and at least one scored related occupation. “Below median exposure” means percentile < 50. Pearson correlation is computed between own percentile and the mean of scored related occupations’ percentiles. Known limitation, disclosed everywhere it matters: occupation codes new in the 2018 SOC taxonomy (e.g., Web & Digital Interface Designers, Video Game Designers) carry no AIOE score; we print “not scored” rather than dropping them silently.

2 · Wages, employment, and outlooks

Figures displayed: median annual wages (2025), employment counts (2024), and projected-growth categories (2024–2034) for 19 occupations across the site — e.g., Customer Service Representatives $44,770 / 2,814,000 / “Decline (−1% or lower)”; Medical Assistants $45,690 / “Much faster than average (7% or higher)”; Electricians $63,190; Web & Digital Interface Designers $104,000; Cashiers $32,880 / “Decline.”

Source: O*NET OnLine occupation summary pages (per-occupation URLs of the form onetonline.org/link/summary/code), fetched 2026-08-15. O*NET OnLine republishes the Bureau of Labor Statistics’ OEWS May 2025 wage estimates and 2024–2034 Employment Projections. Cross-check against BLS directly at bls.gov/oes and bls.gov/emp.

Disclosure: we read these figures from O*NET OnLine’s republication rather than bls.gov directly; the republication is the Department of Labor’s own sponsored surface, and the figures carry BLS’s vintages as labeled.

3 · Exposure and usage readings

AIOE percentiles (73rd — Customer Service Representatives; 77th — Bookkeeping Clerks; 87th — Paralegals; 67th — Graphic Designers; 14th — Truck Drivers; destination percentiles in the sample report): derived 2026-08-15 as in §1. The index was published in 2021, before modern LLMs — a vintage caveat we attach wherever a percentile appears.
Anthropic Economic Index (Customer Service Representatives: usage share 0.07%, rank 203 of 718 published occupations, augmentation 65.7% / automation 34.3%): May 2026 period, dataset snapshot 2026-06-24, retrieved 2026-08-15 via the published dataset interface.

4 · Program prices and training terms

$5,491 — Clinical Medical Assistant Certificate, total in-district approximate cost, 2025–26, with published line items: Northeast Texas Community College program-fees page, fetched 2026-08-15.
$8,999 — Medical Assistant program including NHA CCMA certification exam fee, ~629 instructional hours; textbook ≈$225 separate: Brookdale Community College (NJ), fetched 2026-08-15. Correction note: an earlier internal draft carried $8,499 from a prior listing; the college’s own page said $8,999 on fetch date, so that is the figure we display.
≈$8,899 — Practical Nursing (LPN) certificate of achievement, estimated total in-district tuition and fees, 2025–26 ($287/credit hour): Lincoln Land Community College (IL), fetched 2026-08-15.
$19.25/hr — first-year inside-wireman apprentice rate, IBEW Local 3 (NYC), effective 2026-04-15 (was $18.50 from 2025-04-09): Joint Industry Board of the Electrical Industry rate sheet (PDF), fetched 2026-08-15. Apprentice rates are set per local; this is one published example, not a national figure.
$4,000–$6,000, 160 hours — CDL-A training national range, and “WIOA grants … can cover up to 100% of your CDL tuition” for eligible workers: 160 Driving Academy’s published cost guidance, fetched 2026-08-15. A training seller describing its own market — read it as such; the WIOA mechanism itself is federal (see §5).

Program-level earnings records: U.S. Department of Education College Scorecard field-of-study data and U.S. Census Bureau Post-Secondary Employment Outcomes (PSEO).

6 · Market-context figures

87,714 AI-attributed announced job cuts, 22% of all announced cuts — 2026 through May (the May 2026 report, published 2026-06-04: “For the year, AI has been cited in 87,714 cuts, or 22% of all 2026 layoffs”); AI the most-cited reason for five consecutive months through the July 2026 report (“led all reasons for the fifth consecutive month”) — Challenger, Gray & Christmas monthly job-cut reports (challengergray.com), checked 2026-08-15. Later months add to the YTD total; we quote the last figure Challenger itself published, with its period. Interest disclosure, printed wherever the figure appears: Challenger sells outplacement services; these are announcement attributions, not verified causes.
Price comparisons — Truity $29; CareerFitter $19.95–$39.95; JobTest.org $24.90–$99.90; checked 2026-08-15 against each seller’s published pricing. The $7.99–$19.99 figure for score-plus-pivots reports reflects one seller’s own pages showing both prices (funnel-dependent), checked 2026-08-15 — quoted as a range for that reason. Free full-engine exposure browsers exist (e.g., aiexposure.org), also checked 2026-08-15.

7 · Standing honesty rules

A figure is our reading of the named source on the named date. Sources reprice and revise; the date is part of the figure.
Paid reports re-derive every figure on the order date — they do not reuse this page’s numbers on trust.
Where two credible sources disagree, both appear. Where data does not exist, “no published record” appears. Where an index has a known gap (unscored occupations), the gap is printed.
Publishers’ interests are disclosed next to their figures (see §6).
