Previous Notices and Updates

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.
June 4, 2007: Seasonal factors for auto and truck production have been reestimated using final production data through April 2007 and manufacturers' assembly plans through September 2007. Factors have been revised back to February 2007 and extended through December 2007. Factors for the fourth quarter of 2007 were estimated based on the holiday schedule in place the past three years. Current agreements with domestic manufacturers, however, expire before then. The factors will be updated to reflect any changes made to the holiday schedule as a result of the new agreement and extended through June 2008 after third-quarter production is completed. A comma-delimited text file containing these seasonal factors is available for download.
June 4, 2007: A Federal Reserve Bulletin article, Industrial Production and Capacity Utilization: The 2006 Annual Revision (144 KB PDF) is now available online.

It discusses both the changes in estimation methods introduced in the revision and the revised estimates of IP, capacity, and capacity utilization.
February 15, 2007: The data in this release include preliminary estimates of industrial capacity for 2007.

January 17, 2006: This release no longer contains tables on electric power use by industry. The December 15, 2005, release included results from the final survey of industrial electric power use conducted by the Federal Reserve Board. The rate of response to the voluntary survey had dropped significantly since the early 1990s, and coverage in 2004 was nearly 40 percent lower than at its peak in 1993. A notice seeking comment on the termination of the electric power survey was published in the Federal Register on September 29, 2005; by the end of the public comment period, November 28, 2005, no comments had been received. Although the indexes of electric power use will no longer be updated, the historical indexes will remain available on the historical data webpage for the G.17.
December 15, 2005: This release includes the results from the final survey of industrial electric power use to be conducted by the Federal Reserve Board.
December 6, 2005: The Federal Reserve will discontinue its survey of industrial electric power use with the publication on December 15, 2005, of data for October 2005. The response rate for the voluntary survey had dropped significantly since the early 1990s, with coverage in 2004 nearly 40 percent less than at its peak in 1993. With the publication of the annual revision to the G.17 on November 7, 2005, the monthly indicators for the industrial production indexes for the twenty industries that previously relied on electric power use were changed to production-worker hours for the period 1997 to the present. Although the indexes of electric power use will no longer be updated, the historical indexes will remain available from the historical data page for the G.17. A notice seeking comments on this action was originally published in the Federal Register on September 29, 2005; no comments were received during the public comment period, which ended on November 28, 2005.
