Industry capacity utilization rates measure the potential for short-term expansion and the intensity of current production given currently available capital. Short-term changes in utilization reflect changes in demand and the availability of labor. In the long-run, firms may adjust the amount of capital due to persistent changes in utilization rates.
| Industry Capacity Utilization | Nov-01 | Dec-01 |
|---|---|---|
| Capacity Utilized for Vehicles and Parts | 74.40 | 77.30 |
| Percent Change from Previous Month | 5.22 | 3.90 |
| Capacity Utilized for Transportation Equipment | 71.59 | 72.58 |
| Percent Change from Previous Month | 1.95 | 1.38 |
| Capacity Utilized for Aerospace and Other Industries | 67.20 | 65.27 |
| Percent Change from Previous Month | -3.12 | -2.88 |
NOTES: These data are for the industries with the following Standard Industrial Classification codes: Transportation equipment (37), Motor vehicles and parts (371), and Aerospace and miscellaneous transportation equipment (372-6,9). The latter two consist of three-digit industrial classifications which are components of the two-digit industry classification.
The Federal Reserve Board constructs estimates of capacity and capacity utilization for industries in manufacturing, mining, and energy. A capacity utilization rate is equal to a specified output index divided by the corresponding capacity index. The Federal Reserve Board's capacity indices are designed to quantify the concept of sustainable maximum output within a given industry. Sustainable maximum output is the highest level of output that a plant can maintain within the framework of a realistic work schedule, taking both into account normal downtime and assuming sufficient availability of inputs to operate the capital in place.
Data from September to December 2001 are preliminary.
