Notice of Series Changes with the Update to North American Industry Classification System 2012 and Annual Benchmark Release on February 3, 2012

With the release of January 2012 data on February 3, 2012, the Current Employment Statistics (CES) program updated the National Nonfarm Payroll series to the North American Industry Classification System (NAICS) 2012 from the NAICS 2007 basis and also released the annual benchmark revision. For more information about NAICS in the CES program, see www.bls.gov/ces/naics/home.htm.

Update to NAICS 2012

The conversion to NAICS 2012 resulted in minor content changes within the Manufacturing and the Retail trade sectors, as well as minor coding changes within the Utilities and the Leisure and hospitality sectors. Several industry titles and descriptions also were updated. All employee (AE) series are published at a more detailed level than AE hours and earnings, production employee (PE), women employee (WE), or PE hours and earnings series, collectively called Non-AE series. The Non-AE series were sometimes unaffected or affected at a less-detailed level than the AE series. Consequently, tables are provided below for both the AE and Non-AE series.

Detailed tables on AE series affected by the update to NAICS 2012:

• New AE Series as a Result of NAICS 2012
• Change in Scope of AE Series Due to NAICS 2012
• Discontinued NAICS 2007 AE Series
• Employment Ratio Tables for NAICS 2012 Update
  • NAICS 2007 to NAICS 2012 AE Ratio Table
  • NAICS 2012 to NAICS 2007 AE Ratio Table

Detailed tables on Non-AE series affected by the update to NAICS 2012:

• New Non-AE Series as a Result of NAICS 2012
• Change in Scope of Non-AE Series Due to NAICS 2012
• Discontinued NAICS 2007 Non-AE Series
• Employment Ratio Tables for NAICS 2012 Update
  • NAICS 2007 to NAICS 2012 Non-AE Ratio Table
  • NAICS 2012 to NAICS 2007 Non-AE Ratio Table

Changes as a Result of Annual Sample Review

All CES series are evaluated annually for sample size, coverage, and response rates. Some very small industries no longer have sufficient sample to be estimated and published separately. In some cases all Non-AE series were affected while in others only WE or overtime series were discontinued, as noted in the table titles. The following series were discontinued due to this evaluation:

• Discontinued AE Series
• Collapsed AE Series
• Discontinued Non-AE Series
• Discontinued WE Series
• Discontinued Overtime Series

The CES survey also updated industry titles to reflect similar changes in the NAICS 2012 update. In most cases the scope of each industry is not affected by the title changes, except where the industries are also listed in the "Change in Scope" tables listed above.

AE Ratios

NOTE: This table shows ratios of employment from NAICS 2007 series to corresponding NAICS 2012 series. The table was prepared using second quarter 2011 data from the Quarterly Census of Employment and Wages Program and can be used to evaluate correspondence between NAICS 2007 and NAICS 2012 in the CES series. For example, for CES NAICS 2007 series 31-337129 Miscellaneous household and institutional furniture, approximately 96.1 percent of the employment will go to CES NAICS 2012 series 31-337127 Miscellaneous household and institutional furniture and approximately 3.9 percent to 31-321990 All other wood products.

For example, for CES NAICS 2012 series 31-321990 All other wood products, approximately 97.3 percent of the employment comes from CES NAICS 2007 series 31-321990 All other wood products, and approximately 2.7 percent from 31-337129 Miscellaneous household and institutional furniture. Ratios may not add up to 100 percent for a CES NAICS 2012 series due to rounding.
