Companies
located in the United States that performed or funded research and development
domestically or overseas employed an estimated 27.1 million workers worldwide
in 2008 (table 1).
R&D employees (employees who perform or directly support R&D
activities) accounted for 1.9 million, or 7.1%, of this worldwide employment.
The domestic employment of these companies totaled 18.5 million workers,
including 1.5 million domestic R&D employees.[2]
Thus, domestic R&D employment accounted for 7.9% of companies' total
domestic employment and for 77% of their worldwide R&D employment. In 2008
companies reported $346 billion of company-performed R&D worldwide; 82% of
this activity was performed in the United States.[3]

Workers
engaged in R&D activities have a direct input into the creation and
diffusion of knowledge, and in turn contribute to innovation and economic
growth. The figures in this report are the first employment statistics to be
released from the new Business R&D and Innovation Survey (BRDIS), developed
jointly by the National Science Foundation (NSF) and the U.S. Census Bureau.
These statistics are preliminary; final data will be available in early 2011.[4]
Employment statistics in this InfoBrief refer to headcounts. See "Definitions"
and "Survey Information and Data Availability," below, for further information.
New
measures from BRDIS related to R&D employment that will be available in
future publications include R&D employment by selected occupational
category (engineers, scientists, technicians, and support staff), level of
educational attainment (PhD and other college degrees), and sex. The survey
will also provide the number of non-U.S. citizens with temporary visas (such as
H-1B or L-1) who are employed by industry as R&D scientists and engineers
in the United States.
R&D
Employment Intensity
The
proportion of R&D employment relative to total employment, or R&D
employment intensity, is one indicator of a company's involvement in R&D
activity. Examination of this indicator across the industries into which
companies were classified shows that worldwide R&D employment intensity in
some industries is much higher than the 7.1% figure for the aggregate of all
industries. Scientific R&D services (31%), communications equipment (27%),
and computer systems design and related services (25%) top the list (figure 1).
These three industries plus semiconductor and other electronic components,
software publishers, and pharmaceuticals and medicines accounted for about half
of worldwide company-performed R&D expenditures in 2008 (table 1).
Figure 1 Source Data: Excel file
Domestic
and Foreign R&D Employment
About
1.5 million (77%) of companies' 1.9 million worldwide R&D employees worked
in the United States, and 448,000 (23%) worked at foreign locations of U.S.
companies in 2008 (table 1).
As a group, manufacturing industries reported that 74% of their worldwide
R&D employment was domestic, compared with 80% for nonmanufacturing
industries. Industries with domestic R&D employment shares of 80% or more
included both small R&D-performing industries (less than one billion
dollars in company-performed R&D), such as wood products or primary metals
manufacturing, and large R&D performing industries with historically
significant shares of federally funded R&D. The latter include aerospace
products and parts and scientific R&D services industries.
Only
three industries, all in manufacturing, reported domestic R&D employment as
a percentage of worldwide R&D employment below 70%: communications
equipment, semiconductor and other electronic components, and motor vehicles,
trailers, and parts. This last industry had the lowest domestic R&D
employment share at just over 55% in 2008.
The
closest indicator of domestic R&D employment from the predecessor Survey of
Industrial Research and Development (SIRD) reported 1.1 million full-time
equivalent (FTE) R&D scientists and engineers in 2007. The SIRD measure is
not directly comparable with BRDIS domestic R&D employment figures, which
are headcounts. In general, numbers for headcounts are larger than those for
FTEs whenever companies have employees that devote time to both R&D and
non-R&D functions or have employees that work on a part-time basis.[5]
Further, the BRDIS measure includes not only R&D scientists and engineers
but also their managers, along with technicians and support personnel.
Company-performed
R&D expenditures per R&D employee
Company-performed
R&D per R&D employee varied among domestic and foreign activities.
Worldwide, companies spent about $181,000 on R&D per R&D employee,
whereas the domestic and foreign figures were estimated to be about $194,000 and
$140,000, respectively.[6]
R&D funds spent per R&D employee were higher for manufacturing industries
($210,000) than for nonmanufacturing ($139,000). Within each of these
aggregates the domestic company-performed R&D per R&D employee exceeded
the estimated corresponding foreign figure. The pharmaceuticals and medicines
industry had the largest R&D funds per R&D employee among all 4-digit
industry classifications for worldwide ($378,000), domestic ($396,000), and
foreign ($319,000) activity.
Definitions
Company. A business organization of one or more establishments under
common ownership or control. A company includes all subsidiaries and divisions
in which there is more than 50% ownership, no matter where the subsidiary or
division is located.
Company-performed
R&D. The total of the amount a
company pays for R&D performed in its own locations for its own benefit
plus the amount paid for by others for R&D performed in the company's
locations for others' benefit.
Domestic
locations. The 50 states and the
District of Columbia.
Foreign. All geographic locations except the 50 states and the
District of Columbia.
Full-time
equivalent (FTE). A full-time
equivalent takes into account employees who do not work full-time, and for
BRDIS, employees who do not work on R&D activities full-time. For example,
an employee who works half-time would be counted as one employee on a headcount
basis but as one-half an FTE employee.
Industry. Industry refers to 2-, 3-, or 4-digit codes used by the
North American Industry Classification System (NAICS) or group of NAICS codes
used to publish statistics resulting from the survey. Comparisons in this
report are made among 4-digit industry classifications except for wood products
and primary metals manufacturing, for which 4-digit detail was unavailable.
R&D
employment. R&D
employment refers to headcounts of all employees providing direct support to
either R&D paid for by the company or R&D paid for by others not owned
by the company, such as R&D the company performed under a grant or
contract. R&D employees include scientists and engineers working on R&D
as well as R&D managers, technicians, administrators, clerical staff, and
interns providing direct support to R&D. R&D employees do not include
staff providing indirect support, such as security guards and cafeteria
workers. Leased employees, temps, and on-site consultants are not counted as
R&D employees.
R&D
funds per R&D employee.
Company-performed R&D divided by R&D employment.
Total
employment. All employees
during the pay period that includes 12 March 2008, including employees on paid
sick leave, paid holidays, and paid vacations.
United
States. The 50 states and the
District of Columbia.
Worldwide. All geographic locations, including the United States.
Survey
Information and Data Availability
The
sample for BRDIS was selected to represent all for-profit companies with five or
more domestic employees, publicly or privately held. The resulting sample can
produce estimates for companies that perform or fund R&D or engage in
innovative activities in the United States. Employment estimates are based on
companies that performed or funded R&D. The statistics from the survey are
based on a sample and are subject to both sampling and nonsampling errors.
For
2008, 39,553 companies were sampled representing 1,926,012 companies in the
population. The estimated number of companies that reported worldwide R&D
expense was 58,304 and the estimated number that reported R&D paid for or
funded by others was 11,453. The estimated number that reported both worldwide
expense and funded R&D was 7,679. The overall response rate was 77.4%; the
response rate for the top 500 domestic R&D-performing companies was 92.6%.
Industry classification was based on the dominant business activity for
domestic R&D performance where available. For companies that did not report
business activity codes for R&D, the classification used for sampling was
assigned.
More
detailed information about the survey sample and methodology will be available
in the forthcoming survey description at http://www.nsf.gov/statistics/survey.cfm. Copies of the BRDIS questionnaires and comparisons of
BRDIS with the predecessor survey are available at http://www.nsf.gov/statistics/srvyindustry/about/brdis/. Coefficients of variation and imputation rates for the
statistics in this InfoBrief are available from the authors.
An
InfoBrief on business innovation is being prepared and will present additional
preliminary BRDIS data for 2008. Detailed tables for 2008 will be available in
the report R&D and Innovation in Business: 2008 at http://www.nsf.gov/statistics/ in early 2011. Individual tables may be available in
advance of publication of the full report. For further information, please

reported that respondents employed 16.7 million total workers in the United
States in 2007. However, this measure was based on R&D performers only and
thus excluded companies that funded but did not perform R&D.

[5] SIRD measured R&D employment exclusively
on a full-time equivalent (FTE) basis and focused on R&D scientists and
engineers. Future BRDIS data will also include an FTE measure, but only for
domestic R&D scientists and engineers. Estimates will be available in early
2011.
[6] The closest indicator from SIRD shows that
companies spent domestically $253,858 per FTE R&D scientist or engineer in
2007. The latter is not fully comparable with the domestic figure from BRDIS.
