この出典がどのような性格の値か

BLSの区分は絶対水準ではなく相対順位であり、一次測定でもありません。複数の既存研究が付けた職業別パーセンタイル順位を4段階にまとめた値です。雇用や賃金の予測でもなく、導入確率でもなく、自動化と増強を区別しません。

Values in this tab are predicted labels, not observations. Eloundou et al. (2023) published two rating regimes — human raters and GPT-4 — and the β shown here is derived from the GPT-4 rater basis alone; the same task can take a different value under the other regime. The unit and the meaning differ from the observed shares (%) in the other tabs, so do not place them on the same axis.

関連2026年1月: Frank et al. (arXiv, Jan 2026): unemployment risk in computer and math occupations (SOC 15), which include web developers, began rising in early 2022, before ChatGPT. Graduate cohorts from 2021 onward entered AI-exposed jobs at lower rates than earlier cohorts, with the gap opening before late 2022, pointing to forces that predate generative AI.
