With the release of January 2018 data on February 2, 2018, the Current Employment Statistics (CES) program implemented publication changes related to annual sample review and updated the national nonfarm payroll series to the 2017 North American Industry Classification System (NAICS) from the NAICS 2012 basis. CES series changes resulting from the most recent annual review of sample size, coverage, and response rates are available on the CES New Series page at www.bls.gov/web/empsit/cesnewseries.htm. CES series changes resulting from the update to NAICS 2017 are detailed below.
The CES series changes discussed on this page affected two industries contained in table B-1 of the Employment Situation. Exhibit A details the table B-1 changes.

The CES program updated the national nonfarm payroll series to the 2017 North American Industry Classification System (NAICS) from the NAICS 2012 basis with the February 2, 2018 Employment Situation release. This change is in accordance with the final decision from the Office of Management and Budget (OMB) on recommendations put forth by its Economic Classification Policy Committee (ECPC) in the Federal Register, Volume 81, Number 152. For more information on OMB's decision and directive on the NAICS 2017 update, see www.gpo.gov/fdsys/pkg/FR-2015-08-04/pdf/2015-19022.pdf. For more information on NAICS 2012 and NAICS 2017 classifications and other Federal Register notices involving NAICS, see www.census.gov/naics.
This conversion resulted in minor revisions reflecting content and coding changes within the retail trade, information, financial activities, and professional and business services major industry sectors, as well as a number of consolidations within the durable goods manufacturing, retail trade, and information major industry sectors. Several industry titles and descriptions were also updated. Approximately 4 percent of CES employment was reclassified into different industries as a result of the revision.
Some of the changes associated with the NAICS 2017 update impacted levels of detail not published by CES; therefore, only cases where CES industries were impacted are discussed in detail here. Only the following directly estimated data types are noted in the following tables: employment of all employees (AE), AE average weekly hours (AE AWH), AE average hourly earnings (AE AHE), employment of production and nonsupervisory employees (PE), PE average weekly hours (PE AWH), PE average hourly earnings (PE AHE), and employment of women employees (WE). Directly estimated data types other than AE are collectively called non-AE data types.
For instances where reconstructions were necessary, ratios of employment moving from old CES industries based on NAICS 2012 to new CES industries based on NAICS 2017 were calculated for March 2017 and were applied to historical CES data. These ratios were calculated by assigning both a NAICS 2012-based CES industry and a NAICS 2017-based CES industry to individual report-level data from the longitudinal database (LDB) from the Quarterly Census of Employment and Wages (QCEW) which is used as the CES sample frame. The March 2017 LDB employment was summed by old CES industry based on NAICS 2012 and by new CES industry based on NAICS 2017. Forward ratios were created by dividing the amount of each old NAICS 2012-based CES industry moving to a new NAICS 2017-based CES industry by its total for the old CES industry (see table 4 for AE ratios and table 9 for non-AE ratios). Reverse ratios were created by dividing the amount of each old NAICS 2012-based CES industry moving to a new NAICS 2017-based CES industry by its total for the new CES industry (see table 5 for AE reverse ratios and table 10 for non-AE reverse ratios). For more information about previous CES NAICS conversions and how CES industry codes relate to NAICS codes, see www.bls.gov/ces/naics/home.htm.
AE series are published at a more detailed level than non-AE series. Forward ratios were held constant and applied to each monthly CES employment estimate for the entire history of the series, usually back to 1990, to determine the amount of employment moving from a NAICS 2012 CES industry to a NAICS 2017 CES industry. Average weekly hours and average hourly earnings were recalculated by applying forward ratios to the amount of old total hours and old total payroll to move the correct amount of hours or earnings into the new CES industry. Total hours and total earnings were then averaged using the new employment levels. More information about the calculation of CES estimates for employment, hours, and earnings estimates is available in the CES Technical Notes under Estimation Methods.
The conversion from NAICS 2012 to NAICS 2017 affected CES industry codes in several ways. Some CES series were converted as a whole from their NAICS 2012 industry code to their new NAICS 2017 industry code. Some CES series were combined with other series because their underlying NAICS codes were combined. Other CES series were split into more detailed CES series because their NAICS codes were changed to accommodate new distinct industries. Finally, some CES series are no longer published at the same level of detail under NAICS 2017. Examples of each of these changes are outlined below.
Some AE series were partially or completely combined with other series. For example, in table 1 the CES industry department stores, except discount (42-452111) was combined with a portion of discount department stores (42-452112) to create the new CES industry department stores (42-452200). This is because the associated NAICS 2012 industry code 452111 became NAICS 2017 industry code 452210, and part of NAICS 2012 industry code 452112 became NAICS 2017 industry code 452210. The remainder of NAICS 2012 industry code 452112 became NAICS 2017 industry code 452311, along with all of NAICS 2012 industry code 452910.

Table 2 shows AE series that had changes in scope due to the conversion from NAICS 2012 to NAICS 2017. These new CES industries combined series that were previously published separately or as part of another series. For example, the new CES industry research and development in nanotechnology (60-541713) combined a portion of the old CES industry biotechnology research (60-541711) and a portion of the old CES industry physical, engineering, and life sciences research (60-541712). The remaining part of the old NAICS 2012 CES industry biotechnology research (60-541711) became the new CES industry research and development in biotechnology, except nanobiotechnology (60-541714). The remaining part of the old NAICS 2012 CES industry physical, engineering, and life sciences research (60-541712) became the new NAICS 2017 CES industry research and development in the physical, engineering, and life sciences, except nanotechnology and biotechnology (60-541715).

Table 3 shows AE series that will no longer be published under NAICS 2017. For example, NAICS 2017 combined electronic shopping and electronic auctions (NAICS 454112) and mail-order houses (NAICS 454113) into electronic shopping and mail-order houses (NAICS 454110). The two CES industries associated with the NAICS 2012 industries are 42-454112 and 42-454113. These were deleted and only the higher level CES series, electronic shopping and mail-order houses (42-454100) is now published.

Table 4 shows the proportion of AE employment that was moved from an old CES industry code based on NAICS 2012 to a new CES industry code based on NAICS 2017. Industries that moved directly and completely from a NAICS 2012 CES industry to a NAICS 2017 CES industry have a ratio of 100. NAICS 2012 CES industries that moved only a portion of their employment from the old NAICS 2012 CES industry to a new NAICS 2017 CES industry have ratios of less than 100. Old NAICS 2012 CES industry codes with ratios of less than 100 are listed multiple times to account for the movement of all of their employment. For example, 98.3 percent of discount department stores (42-452112) moved into the new NAICS 2017 CES industry department stores (42-452200). The remaining 1.7 percent moved into the new CES industry warehouse clubs and supercenters (42-452311).

Table 5 shows the proportion of AE employment that was moved to a new CES industry based on NAICS 2017 that came from an old CES industry based on NAICS 2012. For example, 37.8 percent of the new NAICS 2017 CES industry department stores (42-452200) came from the old NAICS 2012 CES industry department stores, except discount (42-452111). The remaining 62.2 percent of the new NAICS 2017 CES industry department stores (42-452200) came from the old NAICS 2012 CES industry discount department stores (42-452112).

Some non-AE series were partially or completely combined with other series, just like their AE counterparts, while other series affected for AE were not affected for non-AE. For instance, in table 6 the old NAICS 2012 CES industries department stores, except discount (42-452111) and discount department stores (42-452112) do not appear because non-AE data types are not published at the same level. Instead, non-AE data types are published for general merchandise stores (42-452000) which was not affected by NAICS 2017 changes.

Table 7 shows non-AE series that had changes in scope due to the conversion from NAICS 2012 to NAICS 2017. Again, these series reflect the same changes as their AE counterparts, but at less detailed levels, and some series affected for AE are not affected for non-AE. For example, in table 7 the old NAICS 2012 CES industry video tape and disc rental (55-532230) does not appear because non-AE data types are not published at the same level. Instead, non-AE data types are published for consumer goods rental (55-532200) which was not affected by NAICS 2017 changes.

Table 8 shows non-AE series that are no longer published under NAICS 2017. Some AE series that were deleted were already not published for non-AE series, and therefore, were unaffected by NAICS 2017 deletions for non-AE. For example, the old NAICS 2012 CES industry warehouse clubs and supercenters (42-452910) was deleted for AE, and its employment was moved into a new NAICS 2017 CES industry. It is already not published for non-AE series, and, therefore, does not appear in table 8.

Old NAICS 2012 CES industries that moved only a portion of their employment from the old NAICS 2012 CES industry to a new NAICS 2017 CES industry have ratios of less than 100. Old NAICS 2012 CES industry codes with ratios of less than 100 are listed multiple times to account for the movement of all of their employment. For instance, 4.9 percent of biotechnology research (60-541711) moved into the new NAICS 2017 CES industry research and development in nanotechnology (60-541713). The remaining 95.1 percent moved into the new NAICS 2017 CES industry research and development in biotechnology, except nanobiotechnology (60-541714).

Table 10 shows the proportion of non-AE employment that was moved to a new CES industry based on NAICS 2017 that came from an old CES industry based on NAICS 2012. For example, 66.8 percent of the new NAICS 2017 CES industry electronic shopping and mail-order houses (42-454100) came from the old NAICS 2012 CES industry electronic shopping and electronic auctions (42-454112). The remaining 33.2 percent of the new NAICS 2017 CES industry electronic shopping and mail-order houses (42-454100) came from the old NAICS 2012 CES industry mail-order houses (42-454113).
