RACE DECLINE.

to the married couple is the same; to this the Harvard graduate 

 is an exception; with botli family size and marriage rate lower than 

 the graduate average and lower than that of the native-born 

 male of IMassachusetls (of a comparable age group — 40-49 years), 

 reproduction per class is naturally less. A Princeton class, if 

 we may take '76 as an example, more than reproduces itself: it 

 reproduces not alone the married couple, 2.7 surviving children to 

 each, but more than reproduces the entire class, 3.3 to each class 

 member, married and unmarried (2.3-net class reproduction). Brown 

 just reproduces itself with 2.26 living children to the married gradu- 

 ates and precisely 2 to each member of the class. 



All classes later than 1870 of other institutions so far considered 

 fail to reproduce themselves, most so Harvard alumni. Yale graduates 

 very nearly reproduce themselves with 2.28 surviving children to the 

 married graduate and a net class reproduction of 1.78 {i. e., for each 

 member of the class). Next comes the single Yale class of '73 with 

 a class reproduction of 1.57 children. The two Bowdoin classes 1875 

 and '77 are represented by 1.5 and the 9 Harvard classes 1872-80 by 



1.3 children for each graduate, married and unmarried (1872-77 by 



1.4 and 1878-80 by 1.19 respectively). 



A great decrease has indeed taken place in the birth rate of 

 graduate families, but not quite to the same extent as among other 

 groups of the same social grade : the wealthy or leisure class, the well- 

 to-do invariably do less towards reproducing themselves than does the 

 population at large; the college graduate, the highly educated male, 

 does more.
