The annual report, Research and Development in Industry: 2000, will be published later this year. To provide data users with the most timely data possible, selected tables from the report are being made available while it is being prepared. The statistics in these Early Release Tables are considered final and are not expected to be revised, though tables could appear in the annual report with minor format changes to conform with report publication guidelines and procedures.
These tables provide statistics on research and development (R&D) expenditures for the years 1997-2000 and on R&D personnel for January 2001. The statistics are produced with results from the annual Survey of Industrial Research and Development and provide national estimates of the total expenditures on R&D performed within the United States by industrial firms, whether U.S. or foreign owned. It is a sample survey that intends to include or represent all R&D-performing companies, either publicly or privately held.
Every year a survey questionnaire is sent to all companies that spend more than $5 million annually on R&D in the United States.  The level of R&D performance is determined by using information from previous surveys or other sources. Remaining firms are subjected to probability sampling and may not receive a questionnaire for a given survey year.
Industry statistics are developed from data collected from individual companies or enterprises. Since the survey is enterprise based rather than establishment based, all data collected for the various subparts of each enterprise (plants, divisions, or subdivisions) are tabulated in the major industrial classification of the company. The resulting industry estimates are reported using the industrial classification of the companies within each industry. National totals are estimated by summing the industry estimates. Beginning with the 1999 survey, estimates are based on the North American Industrial Classification System (NAICS). In prior years, estimates were based on the Standard Industrial Classification (SIC) system. For tables containing estimates for 1997 and 1998, companies in the 1997 and 1998 surveys were assigned NAICS industry codes based on their SIC codes. Consequently, the estimates for 1997 and 1998 are not necessarily representative of the NAICS categories of industries in those years.
The Bureau of the Census, U. S. Department of Commerce, has conducted the Survey of Industrial Research and Development for the National Science Foundation (NSF) since 1957. Census staff conduct the survey under Title 13 of the United States Code, which prohibits publication or release of data or statistics that may reveal information about individual companies. Therefore, in some tables the symbol (D) is used as a footnote reference to indicate that estimates are being withheld to avoid possible disclosure of information about operations of individual companies.
In addition to the tables containing statistics developed from the survey data, the annual report will contain detailed information about the history of the survey, survey methodology, comparability of the statistics, and survey definitions. Survey questionnaires, instructions, and other survey documents will be reproduced also.

 For surveys prior to 1996, a survey questionnaire was sent to all companies that spent more than $1 million annually or that had 1,000 or more employees. See the technical notes in Research and Development in Industry: 1998 for more details.
