Industrial production and capacity utilization: the 2006 annual revision

On December 11, 2006, the Federal Reserve published revisions to its index of industrial production and the related measures of capacity and capacity utilization. The revision affected the data from 1972 through October 2006, but the largest changes were for the period beginning in 2003. From the fourth quarter of 2002 to the third quarter of 2006, industrial production, as revised, increased about 13/4 percentage points less than previously reported. By year, the change in output was revised down a little for 2003, down substantially for 2004, up a little for 2005, and down a touch for 2006. Revisions for previous years were small.
