The BLS’s Occupational Employment Statistics (OES) dataset is the foremost source of occupation data in the US. Emsi’s SOC structure almost entirely follows OES’s, so Emsi will be adopting SOC 2018 with OES.
- Spring 2020: BLS releases OES using hybrid SOC system
- July 2020: Emsi releases 2020.3 datarun using OES’s hybrid SOC system
- Spring 2022: BLS releases OES using SOC 2018 classification for the first time
- July 2022: Emsi releases 2022.3 datarun using OES’s SOC 2018 classification
How OES Works
OES is a survey distributed to approximately 1.2 million businesses. Those businesses are divided in to six groups, one of which is surveyed every six months (November and May). It takes the BLS three years to create a full OES dataset that contains responses from all 1.2 million businesses. OES is released annually, and each annual release is made up of the latest responses from each of the six groups of businesses in the 1.2 million business universe.
Transitioning OES to SOC 2018
Because OES is only completely refreshed every three years, it will take three years to switch it entirely from using the SOC 2010 classification to using SOC 2018. In November 2018, the OES survey was sent to one of the six groups of businesses in SOC 2018 for the first time.The sixth group will receive the survey in SOC 2018 format in May of 2021.
Until May 2021, the active six-panel sample straddles SOC 2010 and SOC 2018, containing responses in both classifications.To match the two classifications for reporting purposes, OES will “roll up” detailed SOCs that are undergoing changes between the 2010 and 2018 classifications to less detailed SOCs that will span both classifications. Rolling up to levels of less detail enables OES to combine data from older panels that reported using SOC 2010 with newer panels that report in SOC 2018. Once all six panels of businesses in the OES dataset have reported using the new classification, the data will be “rolled down” again into the most detailed level of SOC 2018.
