Industrial Production and Capacity Utilization - G.17

About the G.17 RSS Data Download FRED

The Federal Reserve's monthly index of industrial production and the related capacity indexes and capacity utilization rates cover manufacturing, mining, and electric and gas utilities. The industrial sector, together with construction, accounts for the bulk of the variation in national output over the course of the business cycle. The industrial detail provided by these measures helps illuminate structural developments in the economy.

The production index measures real output and is expressed as a percentage of real output in a base year, currently 2017. The capacity index, which is an estimate of sustainable potential output, is also expressed as a percentage of actual output in 2017. The production indexes are computed as Fisher indexes since 1972; the weights are based on annual estimates of value added. The rate of capacity utilization equals the seasonally adjusted output index expressed as a percentage of the related capacity index.

The Industrial Production and Capacity Utilization statistical release is published around the middle of the month. More detailed descriptions of industrial production and capacity utilization are available. In addition, files containing data shown in the release, more detailed series that were published in the G.17 prior to December 2000, and historical data are available from the Data Download Program. Instructions for searching for and downloading specific series are provided as well.
