The Federal Reserve Board plans to issue its annual revision to the index of industrial production (IP) and the related measures of capacity utilization on July 21, 2015, at 10:00 a.m. EDT. The classification system for the industry groups will be advanced to the 2012 version of the North American Industry Classification System (NAICS), and the comparison base year will be advanced to 2012. As part of the reclassification from 2007 NAICS codes to 2012 NAICS codes, changes will be made to a few of the published series. Details are available on the Current Release page and the Data Download Page.
