2 SUMMARY OF DATA ON ORIGIN AND BIRTHPLACE . 
the light of sex distribution and infant mortality rates, suggests that the fertility of the 
Slavic, Latin and Greek stocks in Canada is much greater than that of the British. It 
appears also that the fertility of the French, German and Scandinavian stocks, though 
somewhat greater than that of the British, was not nearly so high as that for the South, 
Eastern and Central Europeans. The proportions of the several groups under ten years of 
age are shown in Chart 16. The seven origins with the largest proportions under ten and 
the seven with the smallest are as follows: —

Each of the first group has a larger surplus of males than have the British stocks in 
Canada. In all cases the infant mortality rates are considerably greater than for the British. 
Both of these factors would make for smaller numbers of children. On the other hand, 
the age distribution of the adults is more favourable to fertility. While larger proportions 
of the men of British origin were away during the war, the differential effect of this cir-

cumstance on the proportions under ten years of age was largely offset by an exceptionally 
high marriage rate among the British between the years 1919 and 1921, which was imme- 
diately reflected in the number of births. Consequently, differences due to war service may 
be neglected. Unfortunately the relative importance of high fertility cannot be isolated 
from the above data. The table is significant. however. in showing the maenitude of the
