Utility Natural Gas in the Producer Price Index Program

Due to a processing error, the December and August 2001 seasonally adjusted indexes for utility natural gas (series ID number wps055) posted on this website from January 11, 2002, until February 13, 2002, were incorrect. The table below shows the originally published and corrected index values. The corrected data are subject to recalculations of seasonal factors in subsequent years and, in the case of the December estimate, normal PPI procedures that recalculate and finalize 4-month-ago values remain in effect. The BLS regrets any inconvenience this error may have caused data users. For further information, call the Section of Index Analysis and Public Information at (202) 691-7705.
