NAICS (North American Industry Classification System)

With the release of January 2018 data on March 12, 2018, the CES survey updated the basis for industry classification to the 2017 North American Industry Classification System (NAICS) from the 2012 NAICS basis.

More information on the 2017 NAICS redefinitions:

This conversion resulted in minor revisions reflecting content and coding changes within retail trade and information sectors for CES State and Area. All CES series affected by the revisions remain in-scope; thus, total nonfarm employment is not impacted in any state or metropolitan area. The majority of the changes associated with the 2017 NAICS update impacted levels of detail not published by CES State and Area; therefore, only the cases in which CES State and Area industries were impacted are shown in detail here.

The conversion from 2012 NAICS to 2017 NAICS can affect CES industry codes in several ways. Some CES series were converted as a whole from their 2012 NAICS industry code to their new 2017 NAICS industry code. Other 2012 NAICS industry codes were partially distributed to multiple new 2017 NAICS industry codes. The impact of the reclassification from 2012 NAICS to 2017 NAICS for CES State and Area can be seen below.
