Expenditures by R&D-performing sectors 



R&D expenditures have increased in all 

 performing sectors without significant interrup- 

 tion from 1960 to 1974 (figure 2-5). However, in 

 all sectors the constant dollar expenditures for 

 1974 were less than a peak year earlier in the 

 period. The largest decline in constant dollars 

 has been in industry where R&Dexpenditures in 

 1974 were 9 percent lower than in 1969, the year 

 of peak spending, and comparable to the 1965-66 

 level. 



Some changes have occurred within the 

 national R&D total in the proportions accounted 

 for by the four sectors. Industry's share, the 

 largest, decreased from 78 percent in 1960 to 69 

 percent in 1974, even while total R&D spending 

 by industry increased. The Federal intramural 

 laboratories expended 15 percent of the total for 



1974 compared to 13 percent in 1960. The 

 university and college portion rose from 5 to 10 

 percent from 19o0 to 1974, while their 

 associated Federally Funded Research and 

 Development Centers remained at about 2 

 percent. 



Scientists and engineers 

 in R&D-performing sectors 



The number of scientists and engineers 

 employed in R&D was lower in each sector in 

 1974 than in some previous year (figure 2-2). In 

 general, the late 1960's were the years of highest 

 R&D employment, corresponding to the years in 

 which R& D funding in constant dollars was at its 

 highest levels. Declines in subsequent years 

 were largest in industry, where the number of 

 scientists and engineers engaged in R&Din 1974
