Units:  Percent of Capacity, Seasonally Adjusted

Frequency:  Quarterly

For a given industry, the capacity utilization rate is equal to an output index divided by a capacity index. The Federal Reserve Board's capacity indexes attempt to capture the concept of sustainable maximum output-the greatest level of output a plant can maintain within the framework of a realistic work schedule, after factoring in normal downtime and assuming sufficient availability of inputs to operate the capital in place.
