US O*NET-SOC Occupation taxonomy (O*NET)

The Occupational Information Network (O*NET) provides occupation data such as knowledge, skills, and abilities needed to perform in a role, as well as education and training requirements and alternate job titles. Lightcast incorporates this data throughout its tools in various ways. Central to the project is the ONET database, containing information which is categorized into the O*NET-SOC occupation taxonomy. The current version used by ONET and Lightcast is the 2019 release, which incorporates the 2018 SOC. Essentially, the ONET-SOC occupations add an extra level of granularity to the SOC taxonomical hierarchy. The 2019 ONET-SOC taxonomy includes 1,016 occupational titles, 923 of which represent O*NET data-level occupations. These are granular subdivisions of the 867 SOC codes, which are further grouped into 459 Broad Occupations, 98 Minor Groups and 23 Major Groups.

ONET releases updates to its database twice a year, which Lightcast incorporates into our quarterly data runs as available. The ONET-SOC occupation taxonomy updates do not follow a schedule, but Lightcast monitors O*NET for updates to the taxonomy as they become available. Source:O*NET
