1. For 1977-87, changes in GDP and in manufacturing gross product originating are calculated using benchmark-years-weighted measures. Changes for those periods for all other industry groups are calculated using fixed 1987 weighted measures. For 1987-90, changes in GDP and in all industry groups are calculated using the fixed 1987 weighted measure. For 1977-90, changes in GDP and manufacturing are calculated using the combination of the two measures. The indexes are shown in table 11. See the box on page 36 for additional information.
