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 2002. The capacity index, which is an estimate of sustainable potential output, is also expressed as a percentage of actual output in 2002. 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. Further Documentation
