CAPACITY UTILIZATION
Manufacturing, Mining, Utilities, and Industrial Materials

February 18, 1986

Capacity u t i l i z a t i o n in manufacturing, mining, and u t i l i t i e s edged
up 0.1 percentage point in January to 80.8 percent. The operating rate in
manufacturing also grew 0.1 percentage point in January while mining u t i l i zation rose 0*9 percentage point* Following gains in the previous two months9
the operating rate for u t i l i t i e s decreased 1.1 percentage point. U t i l i z a t i o n
in total industry is s t i l l somewhat below i t s rate at the start of 1985,
U t i l i z a t i o n in durable goods manufacturing rose Q92 percentage
point in January. In this sector9 both the primary metals and motor vehicles
and parts industries showed strong u t i l i z a t i o n rate increases. The operating
rate in the automobile industry alone rose 2.8 percentage points. Utilization
in nondurable manufacturing held steady in January; even so9 the operating
rate in the petroleum products industry rose by the largest amount of all
major industries, 4.5 percentage points.
Capacity u t i l i z a t i o n in total industrial materials declined
0,1 percentage point in January to 79.6 percent. Energy materials, which
had a 0.5 percentage point f a l l , was the major contributor to the overall
decline in January. Durable materials u t i l i z a t i o n was unchanged while the
nondurable materials operating rate rose Qel percentage point*

Definition. This release contains estimates of output, capacity, and capacity utilization for the
nation's factories, mines, and electric and gas utilities. Output data are the Federal Reserve's
seasonally adjusted indexes of Industrial production, which express output as percentages of
1977 output. The capacity estimates are expressed as percentages of 1977 output as well.
Capacity utilization percentages are calculated as ratios of production to capacity. The capacity indexes are based on a variety of data, including capacity data in physical units compiled
by trade associations, private and government surveys of capacity growth and utilization rates,
and estimates of capital stock growth. The concept of practical capacity is applied, which is
defined as the greatest level of output that a plant can maintain within the framework of a realistic
work pattern, taking account of normal downtime, and assuming sufficient availability of inputs
to operate machinery and equipment in place. When the capacity indexes for individual Industries are aggregated—for example to total manufacturing—no explicit account is taken of possible general equilibrium constraints such as emerging industry bottlenecks. Because of the
large and heterogeneous database, changes in utilization rates may be more meaningful In the
analysis of business conditions than any particular level of these rates.
i of capacity and Industrial production for manufacturing Industries are
aggregated top
ng and advanced processing industries, to durable and nondurable
manufacturing industries, and to total manufacturing. The mining, manufacturing, and utilities
estimates aggregate to the total index. Industrial materials are items produced and used as inputs
by manufacturing plants, mines, and utilities. Industrial materials include many of the items
included in the primary processing grouping of manufacturing, as well as some of the output
of the advanced processing industries, mines, and utilities—such as iron ore, crude oil, semiconductors, and electricity sold to industry.

Perspective. The historical highs and lows in capacity utilization shown in the tables above are
specific to each series and did not all occur in the same month. Industrial plants usually operate at capacity utilization rates that are well below 100 percent: none of the broad aggregates
has ever reached 100 percent. For mining, manufacturing, and utilities as a whole, and for total
manufacturing, utilization rates as high as 90 percent have been exceeded only in wartime.
Revisions. The first estimates for a month are published about the 17th of the following month.
These estimates may revise in each of the next three months as new data become available.
After the fourth month no further revisions are undertaken until an annual or benchmark revision. The median of the revisions in the total manufacturing utilization rate between the first
and fourth estimate is 0.3 of a percentage point; that is, in about half of the cases, the absolute
value of the revision from the first to the fourth estimate is less than 0.3 of a percentage point.
Sources. The basic methodology used to estimate the series is discussed In "Revised Federal
Reserve Rates of Capacity Utilization", Federal Reserve Bulletin, October 1985. Revised data
from 1948-84 are included in the statistical supplement to the July 1985 capacity utilization
release, which may be obtained from Publications Services, Board of Governors of the Federal
Reserve System, Washington, D.C. 20551.
Rounding. Utilization rates are calculated from unrounded capacity and production Indexes. Aggregates are derived from unrounded detailed components.
