Construction of Average Weekly Hours for Supervisory and Nonproduction
Wage and Salary Workers in Detailed Industries
In measuring output per hour for detailed industries, the Division of Industry
Productivity Studies (DIPS) in the Bureau of Labor Statistics (BLS) constructs annual
total hours series for each industry. To construct these series, the Bureau relies primarily
on data collected in the BLS monthly Current Employment Statistics (CES) survey of
U.S. establishments. The CES provides monthly and annual data on total employment, as
well as data on employment and average weekly hours of production and nonsupervisory
workers, by detailed industry. However, the CES does not collect data on the hours of
nonproduction and supervisory workers, and therefore the hours must be estimated. This
report describes the construction of these estimates for detailed industries. 1
Average weekly hours of supervisory and nonproduction workers in each industry
are derived using data from the BLS-sponsored Current Population Survey (CPS), a
monthly household survey, and data from the CES establishment survey. Annual ratios
of supervisory worker average weekly hours to nonsupervisory worker average weekly
hours for each service-providing industry are calculated from the CPS data. Similarly,
ratios of nonproduction worker average weekly hours to production worker average
weekly hours for each manufacturing and mining industry are also calculated. These
ratios are applied to the CES nonsupervisory or production worker average weekly hours,
respectively, for the industry to estimate the nonproduction or supervisory worker
average weekly hours by industry.
In this effort, the Division of Industry Productivity Studies (DIPS) uses data
sources and methods similar to those used by the Bureau’s Division of Major Sector
Productivity (DMSP), described in a report on this website at
www.bls.gov/lpc/lprswawhtech.pdf, and in “Alternative measures of supervisory
employee hours and productivity growth" in the October 2004 Monthly Labor Review,
available at https://www.bls.gov/opub/mlr/2004/04/art2full.pdf. While the methods and
data are similar, some differences occur in constructing industry-specific estimates. This
report will discuss those differences.
The Methodology
Productivity and cost measures for detailed industries are maintained back to
1987. The adjusted hours series discussed here were developed for the period 1987
1
The hours of self-employed and unpaid family workers also are included in industries where those
workers tend to be relatively large. Estimates for self employed and unpaid family workers are not
available from the CES establishment survey and are separately constructed using CPS data. This report
does not discuss the estimation of self-employed and unpaid family worker hours, however.
through 2002. They have since been extended to 2003 and will be updated to current
years in future updates of the industry productivity measures.
Defining nonproduction and supervisory workers in the establishment survey
Estimates of nonproduction or supervisory worker employment in each industry
are derived from the CES establishment survey by subtracting the estimate of production
workers, construction workers, or nonsupervisory workers from the total employees in
that industry. In the CES, production workers in manufacturing and natural resources
and mining refer to employees who engage directly in the production of the
establishment’s products; production workers include working supervisors and group
leaders who may be in charge of a group of employees, but whose supervisory function is
only incidental to their regular work. In construction industries CES data refer to
construction workers, while in utilities industries and in service-providing industries,
CES data refer to nonsupervisory workers. 2 Nonsupervisory workers are defined to
include most employees except those whose major responsibility is to supervise, plan, or
direct the work of others, such as top executive and managerial positions, officers of
corporations, department heads, and superintendents.
Defining nonproduction and supervisory workers in the household survey
In the CPS, respondents are not asked to classify themselves as production,
nonproduction, nonsupervisory or supervisory workers. They are asked, however, to
report on their occupation and employment status. Using this information, we
constructed employment counts and worker categories in a manner that is highly
consistent with the way employers report on workers for the CES.
The CPS microdata that were used cover all private wage and salary workers who
were employed and at work beginning with data for January 1987. We sorted these data
into categories of nonproduction (supervisory) or production (nonsupervisory) workers
based on industry and occupation codes. For data prior to 2000, we define nonproduction
workers in goods-producing industries as those in the following occupational groups:
Executive, administrative, and managerial occupations
Professional specialty occupations
Technical, sales and administrative support occupations
In nongoods-producing industries, supervisory workers are defined as persons in:
Executive, administrative, and managerial occupations
Beginning with data for 2000, the CPS occupation codes are consistent with the 2000
population census. We define nonproduction workers in goods-producing industries to
include the following:
2
The Bureau does not currently maintain productivity measures for construction industries.
2
Management occupations
Business and financial operations occupations
Computer and mathematical occupations
Architecture and engineering occupations
Life, physical, and social science occupations
Community and social service occupations
Legal occupations
Education, training, and library occupations
Arts, design, entertainment, sports, and media occupations
Healthcare practitioners and technical occupations
Sales and related occupations
Office and administrative support occupations
In nongoods-producing industries, supervisory workers include:
Management occupations
Business and financial operations occupations
Using this information, employment and hours of relevant occupational
categories in each industry were grouped to arrive at estimates for production,
nonproduction, supervisory, and nonsupervisory workers consistent with the CES data.
Calculating Average Weekly Hours of Supervisory and Nonproduction Workers
Annual estimates of employment and average weekly hours from the CPS
household survey were constructed as annual averages of the estimates derived from the
monthly survey data. CPS estimates of annual average weekly hours for each industry
were constructed by dividing the sum of average weekly hours for each month in a given
year by the sum of monthly employment in that industry during the year.
Hours data for production and nonsupervisory workers in detailed industries from
the establishment survey are hours paid. At the major sector level, data on the
relationship between hours worked and hours paid from other establishment surveys are
available to convert hours paid to hours worked. This information is not available for
detailed industries. The CPS, however, collects information on hours worked. Because
the estimates of hours obtained from respondents in the CPS reflect hours worked rather
than hours paid, the measure of the employed used in estimating employment and hours
for individual industries from the CPS data was constructed to include those employed
and at work during the survey period, rather than all employees paid. The estimates of
average weekly hours for detailed industries constructed from the CPS data thus use the
ratio of hours worked to employees at work as a proxy for the ratio of hours paid to
employees paid.

Adjustments to Historical CPS Data
Multiple Jobholding
A major redesign of the CPS survey occurred in 1994, causing inconsistencies
between CPS data collected before and after 1994. In particular, prior to 1994 the
monthly CPS household survey data classified individuals only according to the industry
and occupation of his or her primary job. In contrast, from 1994 forward the CPS data
also provide information on the industry and occupation of secondary jobs, and
information on hours worked at both the primary and the secondary job. Beginning in
1994, the CPS data can be combined to be more consistent with the data from the CES
establishment survey, which measures jobs, counting a person who is employed by two
or more establishments at each place of employment. BLS adjusted the CPS data prior to
1994 for multiple jobholding to be consistent with the data for 1994 forward. Adjustment
ratios were constructed from the 1994 CPS data, where employment and hours of
multiple jobholders in all twelve months were classified according to both the old and the
new method. (Additional information was also available from the May 1985, 1989, and
1991 supplements to the CPS, but too few observations were available at the industry
level from these monthly supplements to construct reliable adjustment ratios.) The
industry-specific adjustment ratios based on 1994 employment and hours data were
applied to the pre-1994 data to make them consistent with the later data.
Industry Coding
Industry employment and hours data from the CES establishment survey are
identified with codes pertaining to the North American Industry Classification System
(NAICS). In contrast, the Current Population Survey (CPS) uses the Census Bureau’s
Industry Classification System (ICS) for coding industries. Depending on the year, an
ICS code may represent a detailed industry as classified in the Standard Industrial
Classification (SIC) system or the NAICS system, or a combination of several industries.
CPS data classified at the most detailed ICS industry level were used wherever possible.
From 1987 to 2002, each ICS code corresponds roughly to a 3-digit SIC code,
although in some instances it corresponds to a 2-, 3-, or 4-digit SIC code or combination
of several SIC codes. The ICS industry codes are updated in every decennial Census of
Population to take into account SIC changes that introduce new industries and eliminate
obsolete ones. The period studied, 1987-2002, includes two different SIC-based
classification systems. For the years 1987-1991, the ICS is based on the 1980 Census,
which uses the 1972 SIC classification, as modified in 1977. The ICS for the years
1992-2002 is based on the 1990 Census which uses the 1987 SIC classification. As a
result of the changes made in the SIC and the ICS, some changes to coding were
necessary to keep industries consistent throughout the period of the study. The recoding
was done as the datasets were created.
In recent years NAICS has replaced the SIC system for reporting U.S. data by
industry. In 2003 the CES data were published on a NAICS basis for the first time, and
4
historical series were reconstructed to reflect the new industry structure. The NAICS
system was also officially introduced into the CPS data in 2003, and CPS data for
2000-02 are available on both an SIC and a NAICS basis. In order to have consistent
historical NAICS CPS series back to 1987 for estimating supervisory and nonproduction
worker average weekly hours by industry, the Industry Productivity Studies staff used a
multi-step process to convert the historical CPS data from SIC-based ICS codes to
NAICS-based codes. Using the dual-coded CPS data for 2000-02, SIC to NAICS
conversion ratios were calculated to reflect the percentage of SIC industry employment
accounted for by the employment in each NAICS industry. Adjustments to the initial
conversion ratios were later made based on a comparison of the NAICS industry
employment levels for 2000-02 generated by applying this ratio with the employment
estimates from the CPS data provided on a NAICS basis. NAICS final employment and
hours estimates for 1987-2002 were derived by applying the adjusted conversion ratios to
the historical SIC-based employment and hours series.
Construction of Adjusted Hours Series
Employment, total hours, and average weekly hours series were constructed
separately for supervisory (nonproduction) workers and for nonsupervisory (production)
workers for each ICS industry for the years 1987-2002 using CPS data. Using these
series, the ratios of supervisory worker average weekly hours to nonsupervisory worker
average weekly hours and nonproduction worker average weekly hours to production
worker average weekly hours were calculated for each of 301 ICS industries at the
greatest level of detail available, representing industries at the 3-, 4-, 5-, or 6-digit NAICS
level, as well as combinations of industries. Included were 52 industries that were
created by combining data for detailed ICS industries to more closely represent a 3-digit
NAICS industry.
In using CPS microdata classified by detailed industry, the number of responses
collected for each industry in the household survey was an important factor in assessing
the reliability of the estimates. The employment size of the industry and the volatility of
the constructed annual ratios were also considered. For some industries, the number of
observations was insufficient to produce reliable estimates of employment and hours.
The level of industry detail to be used in calculating the average weekly hours ratios was
based on the number of responses for that industry in the CPS survey. Data for the most
detailed industries classified in the CPS were used wherever possible, as long as the
average number of responses for the industry was 492 or greater per year. For detailed
industries where there were insufficient responses, the average weekly hours ratios were
calculated using data for a more highly aggregated industry.
Once the level of industry detail to be used was determined, ratios of supervisory
(nonproduction) worker average weekly hours to nonsupervisory (production) worker
average weekly hours were calculated from the CPS data. Table 1 shows the level of
CPS industry detail used, as well as the ratios for selected years, for each of the industries
for which BLS maintains output per hour measures. The ratios were then multiplied by
the number of nonsupervisory (production) worker average weekly hours from the
5
establishment survey to create supervisory (nonproduction) worker average weekly hours
for each industry. The supervisory (nonproduction) average weekly hours are then
multiplied by the number of supervisory (nonproduction) workers from the establishment
survey to create total supervisory (nonproduction) worker hours for each industry. These
hours were later combined with the hours of nonsupervisory (production) workers from
the CES and self-employed and unpaid family workers from the CPS to create revised
total hours for each industry.
Results
Previous estimates of supervisory and nonproduction worker average weekly
hours used in most industry productivity measures published prior to the completion of
this research were held constant at levels derived from the discontinued BLS Employer
Expenditures for Employee Compensation (EEEC) survey of 1977 (for manufacturing) or
from the 1980 Census of Population (for non-manufacturing industries).
Effect on Levels of Supervisory and Nonproduction Worker Average Weekly Hours by
Industry
Using the new method for estimating supervisory and nonproduction worker
hours changed the average weekly hours levels of these workers in many industries.
Table 2 compares the 1987-2002 mean supervisory (nonproduction) worker average
weekly hours on the old and new basis for each of 477 unique industries in this study for
which the Bureau maintains output per hour measures. 3
In general, the new levels of nonproduction worker average weekly hours tend to
be higher than the old levels for goods-producing industries. The new levels of
supervisory worker average weekly hours tend to be lower than the old levels for serviceproviding industries, particularly for industries in retail trade and accommodation and
food services. Many of the large revisions in supervisory worker average weekly hours
also occurred in service-providing industries, in retail trade in particular. Of the 477
industries, the mean supervisory (nonproduction) worker average weekly hours were
revised by 10 hours or more in 27 industries. Of those, 25 (93 percent) were in the
service-providing industries and 20 industries (74 percent) were in retail trade.
Effect on Trends in Supervisory and Nonproduction Worker Hours by Industry
The revised supervisory and nonproduction worker average weekly hours also
affected the trends in total hours of supervisory and nonproduction workers for many
industries. 4 Table 3 compares the 1987-2002 average annual percent change in

The industries included in this study are those for which estimates of nonproduction or supervisory
worker hours previously had been based on the 1977 EEEC survey or the 1980 Census of Population.
Industries for which productivity measures were recently developed or that use hours data from an alternate
source are excluded from this study.

Changes were expected. Since average weekly hours of these workers were previously assumed to be
constant, previous trends in the hours of these workers reflected only their employment trends.
6
supervisory and nonproduction worker hours using the old and new average weekly hours
estimates. Chart 1 shows the distribution of these changes among the industries for
which BLS maintains labor productivity measures. Of the 477 industries in this study
for which labor productivity measures are maintained, the impact of the new measures on
the trend in the hours of these workers was minor (a difference of plus or minus 0.1
percent or less in the average annual change between 1987 and 2002) for 148 industries
(31 percent). For 195 other industries (41 percent), the average annual change in
supervisory and nonproduction worker hours was revised from (±) 0.2 to 0.4 percentage
points per year. In 134 industries (28 percent) the trend in hours of supervisory and
nonproduction workers was revised by (±) 0.5 percentage points per year or more. In 28
of these industries, the average annual percent change in hours of those workers was
revised by one percentage point per year or more. Five of the 28 most affected industries
were in the retail trade sector (NAICS 44-45), while five were in the information sector
(NAICS 51) and another 11 were in the manufacturing sector (NAICS 31-33).
Concentration of Supervisory and Nonproduction Workers by Industry
The extent to which changes in supervisory and nonproduction worker hours
affect total labor hours depends in part on the concentration of supervisory and
nonproduction workers in the industry. Table 4 below shows the 1987-2002 average
concentration of supervisory and nonproduction workers by industry, based on CES data.
In general, the concentration of nonproduction workers in manufacturing industries tends
to be higher than the concentration of supervisory workers in service industries. Of the
22 industries where nonproduction or supervisory workers exceeded 50 percent of all
workers, twenty-one were in manufacturing.
Effect on Trends in Total Labor Hours by Industry
Table 5 below shows the 1987-2002 trend in total hours on a new and old basis,
by industry. Because supervisory and nonproduction workers are only a portion of all
workers in each industry, trends in total industry hours were less affected than the trends
in supervisory or nonproduction worker hours. The average annual percent change in
total labor hours for 1987-2002 was revised up or down by 0.2 percentage points or more
in 95 of the 477 industries examined. However, changes of 0.5 percentage points per
year or more occurred in only 8 industries. The largest revision in total hours growth
from 1987 to 2002 was in other electrical equipment and components, NAICS 3359,
where average annual hours growth increased by almost 0.9 percentage points. Of the 8
industries where trends in total hours were most impacted, 5 are in the manufacturing
sector.
Chart 2 shows the distribution of the revisions to the 1987-2002 average annual
percent change in hours that resulted from the adjustment of the supervisory and
nonproduction worker average weekly hours series.

Conclusions
With the construction of new supervisory and nonproduction worker average
weekly hours estimates for detailed industries, both the levels and the1987-2002 trends of
these series changed for many industries. These changes affected the levels and trends in
total supervisory and nonproduction worker hours, which in turn induced changes over
the period in total hours of all workers. Change was expected since the previous
estimates were based on the assumption that supervisory and nonproduction worker
average weekly hours were constant over time.
The trend in hours of supervisory and nonproduction workers was revised by
more than half a percentage point per year in about a third of all the industries examined.
However, for many industries the new measures did not have a major effect on the trends
in total hours. The 1987-2002 average annual percent change in total labor hours was
revised up or down by more than 0.5 percentage points in only 8 industries. The impact
of the revisions to supervisory or nonproduction worker average weekly hours on the
trends in total hours for an industry depended on a variety of factors, including the
magnitude of the revisions to supervisory (nonproduction) worker average weekly hours
levels, the concentration of supervisory or nonproduction workers in the industry, and the
trends in the CPS-based adjustment ratios.
