Important Information Regarding Industry Multifactor Productivity Data Tables
Industry Multifactor Productivity Data Tables
The industry multifactor productivity indexes show the change over time in the
relationship between the output of an industry and the combined inputs of labor, capital,
and intermediate purchases used in producing that output. Multifactor productivity
measures are currently published for 108 3-digit SIC manufacturing industries, railroad
transportation, and air transportation. Multifactor productivity series for an additional 32 3-digit manufacturing
industries were withheld from publication because they did not meet BLS publication
standards. Data for these industries are available upon request from the Office of
Productivity and Technology (202-691-5618) or by e-mail (dipsweb@bls.gov).
Industry Multifactor Productivity
Measures of multifactor productivity are useful for analyzing trends in total costs and
overall efficiency, and for studying the effects on labor productivity of changes in
capital relative to labor and intermediate purchases relative to labor. Multifactor
measures are also useful for studying the utilization of the nonlabor inputs - capital and
intermediate purchases - over time. The multifactor productivity measures are constructed
by calculating the ratio of an output index to an input index comprised of a weighted
average of employee hours, capital services, and intermediate purchases (including
materials and supplies, energy, and purchased services). Inputs are weighted together
using cost weights representing each input's share of total output to develop the combined
inputs index. Although the industry multifactor productivity measures relate output to a
combination of several categories of inputs, they still reflect the impact of many other
influences such as economies of scale, capacity utilization, and skill and effort of the
work force as well as technological change. Multifactor productivity measures can be
thought of as labor productivity measures adjusted to remove the effects of changes in
capital per hour and intermediate purchases per hour.
The following index series are contained in the industry multifactor productivity data
tables.
