Emsi SOC

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

Vintage: 2010 (with adjustments)

Emsi follows OES’s SOC structure, since OES is our primary source of occupation data. OES currently uses SOC 2010 but with some combinations they introduced in 2017. For example, beginning with 2017 OES, OES combined SOCs 29-2011 (Medical and Clinical Laboratory Technologists) and SOC 29-2012 (Medical and Clinical Laboratory Technicians) into one SOC. All Emsi dataruns from 2018.3 on use this slightly rolled-up version of SOC 2010.

For more information on the 2017 SOC roll-ups from the BLS, see this page. We recommend that users looking for a missing SOC code (or wondering where a new SOC code came from) check this cheat sheet.

Emsi SOC Particularities

As noted above, Emsi generally uses the flavor of SOC particular to the BLS’s OES dataset, since this is the primary source of our occupation data. Listed below are some common Gotchas.

  • Emsi does not use SOC codes for military occupations due to lack of good data. Emsi uses one aggregate code, 55-9999, for all 20 military occupations in standard SOC codes.
  • Emsi 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 Emsi Data’s research on this topic, click here.
  • Emsi 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 OES, Emsi adds the code 25-3098 (Substitute Teachers).

Updating to SOC 2018

Since OES is a three-year rolling survey, it will take the BLS several years to switch OES fully to SOC 2018. Emsi will follow OES’s implementation of SOC 2018; therefore we anticipate switching to SOC 2018 with our 2022.3 datarun, which will be released shortly after the BLS releases OES in SOC 2018. For more information on the timeline for the switch, see this article.
