Notices and Updates

• September 15, 2008: Capacity utilization rates for October 2007 through February 2008 have been updated with this release. In April 2008, a six-month reporting window was instituted for the industrial production indexes in the G.17 Statistical Release; however, the capacity utilization rates inadvertently continued to be calculated for only a four-month window. Table 7A shows the revised rates for the affected months. The data download program and the historical data files on the Federal Reserve Board's website have been updated with revised data.
• September 15, 2008: The Federal Reserve Board plans to issue an annual revision to the index of industrial production (IP) and the related measures of capacity and capacity utilization around the end of March 2009.
• September 15, 2008: The publication dates for 2009 are now available.
• August 11, 2008: A Federal Reserve Bulletin article, Industrial Production and Capacity Utilization: The 2008 Annual Revision (858 KB PDF) is now available online. The article reviews the 2008 annual revision to the index of industrial production (IP) and the related measures of capacity and capacity utilization. It discusses both the changes in estimation methods introduced in the revision and the revised estimates of IP, capacity, and capacity utilization.
• June 17, 2008: Seasonal factors for auto and truck production were revised in June 2008 and extended through December 2008. These factors were based on production data through April 2008 and were revised back to December 2007. Seasonal factors will next revise in mid-October 2008, after production data for the third quarter are available. A comma-delimited text file containing these seasonal factors is available for download.
• April 16, 2008: Monthly releases now include new or revised indexes for a six-month reporting window, which encompasses one month of new data and revisions to the previous five months of data. The new longer reporting window allows the incorporation of additional lagging data before an annual revision. Had a six-month window been used over the past year, an additional 3 percent to 4 percent of IP would have reflected source data. For a few indexes, the longer reporting window will cause the latest month of data shown to be as many as five months earlier than the latest value for aggregate IP; data for detailed production indexes are not shown in the supplement to the G.17 release until either the underlying data are available or the reporting window is closed.
• April 1, 2008: Beginning with the release of March data in the Federal Reserve's monthly G.17 Statistical Release, monthly releases will be based on a six-month reporting window: One month of new data will be reported, and the previous five months of data will be revised. For example, the monthly release to be issued on April 16, 2008 will include new data for March and revised data for October 2007 through February 2008. Previously, the monthly releases were issued with a four-month reporting window, which covered one month of new data and revisions to the previous three months of data.
• March 28, 2008: The Federal Reserve Board issued its annual revision to the index of industrial production (IP) and the related measures of capacity and capacity utilization. The data files and Data Download Application will have updated industrial production, capacity, and capacity utilization data at about 2:00 p.m. The vehicle assembly data was updated for the new seasonal factors at about 3:30 p.m.
• March 28, 2008: Seasonal factors for auto and truck production were revised in March 2008 and extended through September 2008. These factors were based on production data through September 2007 and were revised back to January 2005. Pending the release by the motor vehicle manufacturers in early June of initial assembly plans for the third quarter, seasonal factors will next revise on June 13, 2008 and extend through December 2008. A comma-delimited text file containing these seasonal factors is available for download.
• March 20, 2008: The Federal Reserve Board announced today that it will publish the annual revision to the G.17 statistical release, Industrial Production and Capacity Utilization, on Friday, March 28, at 2 p.m. EDT.
• February 15, 2008: The data in this release include preliminary estimates of industrial capacity for 2008. Measured fourth quarter to fourth quarter, total industrial capacity is projected to rise 1.9 percent this year after having expanded 1.8 percent in 2007. Manufacturing capacity is estimated to increase 2.1 percent in 2008, the same amount as in 2007. In 2008, mining capacity is estimated to expand 0.7 percent, and utilities capacity is projected to rise 1.9 percent; both rates of increase would be slightly faster than for last year. With the publication on March 28, 2008, of the annual revision to industrial production, capacity, and capacity utilization, these estimates will be updated to reflect more-comprehensive source data, including the 2006 Survey of Plant Capacity, physical capacity data from government and trade sources, and the revised production indexes.
• February 15, 2008: The Federal Reserve Board plans to issue an annual revision to the index of industrial production (IP) and the related measures of capacity and capacity utilization on March 28, 2008.
• November 16, 2007: Seasonal factors for auto and truck production have been reestimated using final production data through September 2007 and updated holiday schedules for the domestic manufacturers. Factors were revised for November and December 2007 and have been extended through June 2008. The higher seasonal factor for November 2007 results from one fewer November holiday (local election day) than was present in the previous labor agreements. Seasonal factors will next revise at the time of the annual revision to the index of industrial production, currently planned for the end of March 2008. A comma-delimited text file containing these seasonal factors is available for download.
• August 15, 2007: The Federal Reserve Board plans to issue an annual revision to the index of industrial production (IP) and the related measures of capacity and capacity utilization around the end of March 2008.
• June 15, 2007: This release includes the semiannual update to the capacity estimates for 2007. The estimated rate of increase in total industrial capacity from the fourth quarter of 2006 to the fourth quarter of 2007 is 1.8 percent, a downward revision of 0.3 percentage point from the initial estimate in mid-February; the rate of change for manufacturing capacity was revised down by a similar amount.
