Corrections to Employment Cost Index Data

Employment Cost Index data for June 2009 through September 2010, as originally published, contained errors for several series. Corrections for the affected series were posted on the BLS Web site on Tuesday, January 18, 2011. Corrected data are available at https://www.bls.gov/ncs/ect/data.htm.

The specific data series that contained statistically significant differences (when compared to the original estimates) for one or more reference periods, for 3-month and/or 12-month percent changes, are listed below:

Additional series were also corrected where the corrected data were different from the original data but those differences were not statistically significant. A listing of those series is at: https://www.bls.gov/ncs/ect/eci_notsig_table.htm.

Corrected data are available at www.bls.gov/ncs/ect/data.htm. In addition, the following listings have been corrected:
