Current Employment Statistics - CES (National)

Seasonal Adjustment Files and Documentation

Most series published by the Current Employment Statistics (CES) program have a regularly recurring seasonal movement that can be measured from past data. Seasonal adjustment eliminates the part of the change attributable to the normal seasonal variation and makes it possible to observe the cyclical and other nonseasonal movements in CES series. Seasonally adjusted series are published monthly for selected employment, hours, and earnings estimates.

Table of Contents

Use the links below to skip to specific topics about the CES seasonal adjustment research, first and second preliminary estimates specification files, and other files used for seasonal adjustment.

Technical Information

More information about seasonal adjustment methodology in the CES program is available in Seasonal adjustment in the Calculations section of the CES Handbook of Methods. Technical information and a detailed description of input files and methodology is available in the CES Seasonal Adjustment Technical Notes.

Research

Technical research related to seasonal adjustment in the CES program is outlined in the papers below:

  • "Concurrent Seasonal Adjustment for Industry Employment Statistics" (2002) — This research compares concurrent seasonal adjustment to projected-factor seasonal adjustment and discusses the implications of a conversion to concurrent seasonal adjustment by the CES program. (HTML) (PDF)
  • "Adjusting for Calendar Related Fluctuations in Average Weekly Hours and Average Hourly Earnings Series" (1998) — This research discusses distortions in the CES hours and earnings series caused by differences between reference periods in any given pair of months. In highly seasonal months and industries, this variation can be an important determinant of the magnitude of seasonal hires or layoffs that have occurred at the time the survey was taken, thereby complicating seasonal adjustment. (HTML)
  • "Adjusting for a Calendar Effect in Employment Time Series" (1996) — This research discusses inconsistencies in the seasonally adjusted series that arise because of variations of 4 to 5 weeks between the reference periods in any given pair of months. In highly seasonal months and industries, this variation can be an important determinant of the magnitude of seasonal hires or layoffs that have occurred at the time the survey was taken, thereby complicating seasonal adjustment.

Input Files

Note

All seasonal adjustment input files below have been compressed into ZIP files. A ZIP file utility is necessary to extract the files. For more information please visit How to View ZIP Files.

Specification files used to produce seasonally adjusted data for first preliminary estimates

The specification files in this section are equivalent to the files available prior to the 2012 CES benchmark release. The ZIP file containing the prior adjustments file and manual outliers file is now in the Other data used in seasonal adjustment section.

The specification files available in this section are used to produce seasonally adjusted data for first preliminary estimates. These files are used as inputs to X‑13ARIMA‑SEATS for the CES seasonally adjusted series that aggregate to total nonfarm. Not all specification files in these folders correspond to series that are released with first preliminary estimates. More information about the specification files in these ZIP files is available in the CES Seasonal Adjustment Technical Notes. In addition, the readme text file available within each of the ZIP files provides a brief description of and viewing instructions for the specification files.

Seasonal adjustment input specification files are grouped by data type:

Specification files used to produce independently seasonally adjusted data for second preliminary estimates

The specification files in this section relate to detailed series not published prior to the 2012 CES benchmark release. The ZIP file containing the prior adjustments file and manual outliers file is now in the Other data used in seasonal adjustment section. The prior adjustment file is appropriate for use with these series; however, manual outliers identified for the first preliminary estimates are not applied to any detailed seasonally adjusted series available at the second preliminary estimates release.

The specification files available in this section are used to produce independently seasonally adjusted data for second preliminary estimates. These files are used as inputs to X‑13ARIMA‑SEATS for the CES independently seasonally adjusted series. More information about the specification files in these ZIP files is available in the CES Seasonal Adjustment Technical Notes. In addition, the readme text file available within each of the ZIP files provides a brief description of and viewing instructions for the specification files.

Seasonal adjustment input specification files are grouped by data type:

Other data used in seasonal adjustment

The other input files in this section are equivalent to the other input files available prior to the 2012 CES benchmark release. The prior adjustments file and manual outliers file are available in the ZIP file below. The prior adjustment file is appropriate for use with all series; however, manual outliers identified for first preliminary estimates are not applied to any detailed, independently seasonally adjusted series available at the second preliminary estimate release.

The other input files available in this section are used as inputs to X‑13ARIMA‑SEATS for CES seasonal adjustment. This ZIP file includes user-defined regression files, a file of prior adjustments, and a file containing recent outliers. More information about the files in this ZIP file is available in the CES Seasonal Adjustment Technical Notes. In addition, the readme text file available within the ZIP file provides a brief description of the files and instructions.

Other seasonal adjustment input files:

Updates to input files and availability of historical input files

Annually, BLS updates the specification files and prior adjustment file to reflect the updated series structure for that year. Monthly with each release of CES estimates, BLS updates the prior adjustment file and recent outlier file.

The annual specification files from 2005 forward are available upon request by contacting CES by email or by phone at 202‑691‑6555.

Model Specifications

Model specifications tables provide mode (additive or multiplicative) and adjustment type (4/5 week, 10/11 day, Easter/Labor Day, etc.) information about the model selected for each CES series. The tables listed below include information for CES series that aggregate to total nonfarm. More information about mode and adjustment types in the CES application of seasonal adjustment is available in Seasonal adjustment in the Calculation section of the CES Handbook of Methods.

Tables are available for the following data types:

  • All employees (AE)
  • AE average weekly hours (AE AWH)
  • AE average hourly earnings (AE AHE)
  • AE average weekly overtime hours (AE AWOH)
  • Production employees (PE)
  • PE average weekly hours (PE AWH)
  • PE average hourly earnings (PE AHE)
  • PE average weekly overtime hours (PE AWOH)
  • Women employees (WE)

Updates to model specifications and availability of historical model specifications

The seasonal adjustment model specifications tables are updated annually. Historical annual seasonal adjustment model specifications tables for 2003 to 2013 can be found on the Archived CES Benchmark Articles webpage.

The more recent annual seasonal adjustment model specifications tables are available upon request by contacting CES by email or by phone at 202‑691‑6555.
