doctorates increased in each group of institu- 

 tions, the smallest growth occurred in the first 

 and second 20 institutions. As a result of this 

 pattern, the proportion of all such doctorates 

 awarded by the first 20 institutions declined 

 from 51 to 39 percent between 1962-63 and 

 1970-71, as compared with a nearly constant 

 proportion of 20 percent for the next 20 institu- 

 tions and an increase from 29 to 42 percent for 

 the remaining institutions. 



Growth and distribution patterns similar to 

 these occurred for graduate student enroll- 

 ments, as shown in figure 56. Total full-time 

 enrollments increased overall, although a small 

 decline was recorded among the first 20 institu- 

 tions in 1970-71. By the end of the period, the 

 share of total enrollments for the first group of 

 institutions had declined to 33 percent, down 

 from 43 percent in 1962-63. The share for the
