This page includes information from the O*NET 31.0 Database (opens in a new tab) by the U.S. Department of Labor, Employment and Training Administration (USDOL/ETA). Used under the CC BY 4.0 (opens in a new tab) license. O*NET® is a trademark of USDOL/ETA. Orbyt Labs has modified all or some of this information. USDOL/ETA has not approved, endorsed, or tested these modifications.
The changes: Orbyt Labs matched each O*NET® job title to its 6-digit occupation code, removed duplicates, and kept the 14,832 of 51,533 titles listed by the most O*NET® sources, for search only.
Anthropic's Claude use release has a share for 614 of these 807 occupations, its observed exposure a figure for 756, and OpenAI for 800. Orbyt matched all three by occupation code; it summed Claude use over each occupation's O*NET codes and averaged the release's months, and rounded the other two to whole percent. A job title finds its occupation through Orbyt's salary roles or O*NET® job titles, so the figures describe that occupation, not the title. Where a source splits an occupation into finer codes, Orbyt shows their plain average. A rank compares an occupation only with the others the same source measured: the share of them with a strictly lower figure.
