Section A. Detailed Statistical Tables

Table Notes List of Tables

These notes pertain to the tables in this section and in section B, except as noted in footnotes and other explanatory information at the end of specific tables.

Company Size 

Companies were categorized by total number of domestic employees. The following are the size classes used in this report (see Comparability of Statistics in section B for information on how this expanded array of company size classes compares to size classes used previously):

• 5–24 employees
• 25– 49 employees
• 50–99 employees
• 100–249 employees
• 250–499 employees
• 500–999 employees
• 1,000–4,999 employees
• 5,000–9,999 employees
• 10,000–24,999 employees
• 25,000 or more employees

The survey excludes companies with fewer than five employees to limit burden on small business enterprises in compliance with the Office of Management and Budget's (OMB) guidelines for Federal government data collection activities.

Current and Constant Dollars 

Statistics in all tables are reported in current dollars. Constant dollars also are presented in the summary tables (A-1, A-24, A-25, and A-26). Gross domestic product (GDP) implicit price deflators were used to convert current to constant dollars (see The Methodology Underlying the Measurement of R&D Expenditures: 2000 (Data Update) at http://www.nsf.gov/statistics/srs02902/srs02902.pdf for a detailed discussion of the application of the deflators).

Disclosure and Suppression of Statistics 

Title 13 of the United States Code and a pledge of confidentiality to respondents prohibit publication or release of data or statistics that may reveal information about individual companies. Therefore, the data in some table cells have been deleted and replaced with "D." This occurs when a small number of companies account for a large percentage of the estimate in a particular data cell. Although publication of certain cells may be withheld, the estimates in the cells are always included in totals. The tables most often affected by cell suppression are those that contain data on Federal support for industrial R&D performance.

Geographic Statistics 

The statistics in this report cover only those operations located in the 50 U.S. states and the District of Columbia (D.C.). Statistics on company-sponsored R&D performed outside the 50 U.S. states and D.C. by foreign subsidiaries of U.S. domestic companies are included in tables A-11 and A-12 but excluded from all other tables.

Historical Statistics 

Prior to the 1999 report, tables classified by industry contained the current survey's statistics plus statistics for 10 previous years. Because of the new classification system (see below), these tables now contain only statistics for the current year and prior years back through 1999. In Research and Development in Industry: 2000 an effort was made to provide a bridge for users who wanted to make year-to-year comparisons below the aggregate level. In several tables statistics from the 1997 and 1998 cycles of the survey, which were previously classified and published using the standard industrial classification (SIC) system, were reclassified using the new North American Industrial Classification System (NAICS) codes. These reclassified statistics were published using their new NAICS classifications and were shown alongside the 1999 and 2000 statistics, which were estimated using NAICS from the outset.

Industry Classification 

One North American Industrial Classification System (NAICS) code was assigned to each company. Multiestablishment companies were assigned a single code based on the most dominant aggregated activity for that firm in terms of total payroll. Statistics for the following industries and industry groupings are published in this report (NAICS codes are given on the right) (see Comparability of Statistics in section B for information on NAICS and how it compares with the Standard Industrial Classification (SIC) system used in reports prior to the 1999 edition. The 1997 version of NAICS was used for the 1999–2001 surveys):

For 1999, 2000, and 2001, the frame from which the statistical samples were selected was divided into two partitions based on total company employment. In the manufacturing sector, companies with employment of 50 or more were included in the large company partition. In the nonmanufacturing sector, companies with employment of 15 or more were included in the large company partition. Companies in the respective sectors with employment below these values but with at least 5 employees were included in the small company partition. The purpose of partitioning the sample this way was to reduce the variability in industry estimates largely attributed to the random year-to-year selection of small companies by industry and the high sampling weights that sometimes were assigned to them. Therefore, in the 1999 and 2000 reports detailed industry statistics were published only from the large company partition; detailed industry statistics from the small company partition were not. Statistics from the small company partition were included in the manufacturing, nonmanufacturing, and all industries totals but were aggregated into "small manufacturing" and "small nonmanufacturing" classifications instead of being included in their respective industry classifications. For the 2001 report, this practice was evaluated and discontinued because it was determined that the data for small companies are more useful if they are included in their respective industries even given the sampling concerns described above. Consequently, the "small manufacturing" and "small nonmanufacturing" stublines are no longer present. For 1999 and 2000, statistics previously published for the firms in the small company classifications are included in the manufacturing, nonmanufacturing, and all industries totals. (See Frame Creation and Sample Selection in section B for more information on the 5-employee cutoff and partitioning of the statistical sample.)

Nonresponse and Imputation 

For various reasons, some firms did not choose to return the survey form or returned it with one or more blank items. (See Survey Nonresponse in section B for more information on the reasons for unit and item nonresponse.) Missing data for major data items were estimated using mathematical algorithms developed from industry comparisons, data from previous cycles of the survey, and other information. Therefore, the statistics in some table cells may be accompanied by the notation "S," which indicates that the imputation rate—the percentage of the statistic not reported by respondents and consequently estimated—exceeds 50 percent for that item. In such cases, the estimate may be statistically unreliable. See table B-5 for imputation rates for specific items.

Percentages 

Percentages were calculated on the basis of thousands of dollars and may differ slightly from those calculated using the rounded figures shown.

Reporting Unit 

The basic reporting unit was the company, firm, or enterprise that included all establishments under common ownership or control. All R&D expenditures and all information about scientists and engineers of each company were classified into a single NAICS code and size category.

Rounding 

Because of rounding, detail items may not add to totals. Most money amounts are expressed in millions of dollars and are rounded down if less than $500,000 or up if $500,000 or more. Frequency estimates (e.g., number of companies) are accumulated from decimal weights assigned to company records (see Weighting and Maximum Weights in section B for information on how company records are weighted) and are rounded down if less than 0.5 and rounded up if 0.5 or greater. Most employment counts (e.g., number of scientists and engineers) are expressed in thousands and are rounded down if less than 500 or up if 500 or greater.

Zeroes 

Zeroes are shown in the tables when numerical values are accumulated from the statistical file to estimate a particular cell and the accumulated sum rounds to or equals zero. In the latter case, this accumulated sum is sometimes referred to as a "true zero". In the cases where there were no numerical values to accumulate, the cell is filled with "—" indicating that data were not collected. For example, in all tables cells for "other manufacturing" contains "—" because data were not collected.[4]

Footnotes

[4] With the advent of NAICS, data for the "other manufacturing" classification were not collected because all of the possible NAICS manufacturing industry classifications are represented elsewhere in the industry stub. In future years as NAICS is expanded, it is likely that data will be collected for the "other manufacturing" classification.
