Lightcast SOC
Updated over a week ago

This article details the particulars of Lightcast SOC codes, outlining where they differ from standard SOC and why.

Lightcast SOC 2021

Lightcast follows OEWS's SOC structure, since OEWS is our primary source of occupation data. As of Spring 2022, OEWS is using SOC 2018.

Because of the deviations laid out below, Lightcast refers to the codes internally as SOC 2021, aligning with the first OEWS data release that included the codes. The taxonomy aligns with the 2018 SOC System.

Lightcast SOC Particularities

As noted above, Lightcast generally uses the flavor of SOC particular to the BLS's OEWS dataset, since this is the primary source of our occupation data. Listed below are some common "Gotchas" where OES and Lightcast differ from the standard SOC classification.

  • Lightcast does not use SOC codes for military occupations due to lack of good data. Lightcast uses one aggregate code, 55-9999, for all 20 military occupations in standard SOC codes.

  • Lightcast uses a single aggregate code (25-1099) for all postsecondary teachers instead of the 38 detailed codes in standard SOC. This is due to lack of solid data. To read Lightcast's research on this topic, click here.

  • Lightcast adds the code 99-9999 for “Unclassified Occupation” to the Extended Proprietors class of worker in industries where we cannot reliably estimate occupations due to lack of data.

  • Following OEWS, Lightcast adds the code 25-3098 (Substitute Teachers).

  • Lightcast also ignores ONET codes that don't have any ONET-assigned tasks. These mostly consist of catchall "All Other" categories.
