Research and Development in Industry 1992 - Notes

Notes

TO USERS OF THE STATISTICS IN THIS REPORT:

To obtain accurate historical statistics, use only the latest detailed statistical tables in this report and not those published earlier. Statistics in trend tables are derived from the most recently completed survey cycle. Data for prior years are reviewed for consistency with current-year responses and are revised when necessary. Consequently, this report contains the latest revised statistics from the Survey of Industrial Research and Development.

As a result of a new sample design, statistics for 1988-91 have been revised. These statistics now better reflect R&D performance among firms in the nonmanufacturing industries and small firms in all industries. See the technical notes in section B for more information.
