RATE OF CONVICTIONS OF CANADIAN BORN AND IMMIGRANTS 201 
In Table A it is seen that 719 convictions occurred in 1924 per 100,000 males in Canada 
between the ages of 16 and 20 inclusive. Table C shows that 9.4 p.c. of the Canadian born 
males in 1921 were in that age group. Applying that rate to the Canadian born males 16-20, 
it is apparent that 9.4 p.c. of 719 or 67.6 would be the number of males at those ages per 
100,000 Canadian born males (all ages), who would be convicted of indictable offences. 
Applying the rates 501 and 180 respectively in a similar manner to other age groups, it is 
found there would be 120.2 convictions of Canadian born males between the ages of 21 and 
39 inclusive and 41.9 for the group 40 and over. Adding the numbers so computed for the 
three age classes a total of 229.7 is secured as the number per 100,000 Canadian born males 
(all ages) who would be convicted of indictable offences on the basis of age distribution as it 
actually existed in 1921, and on the assumption that crime at the various ages was neither 
more nor less prevalent among Canadian born males than among the male population as a 
whole in 1924 (the standard year). Like computations were made for the other British and 
Foreign born males and 4 summary appears in Table E. In Table F are presented similar 
data for females of each nativity group. -.

The totals in the last two tables give an index of the allowance that must be made 
on the score of age distribution in comparing the different nativity groups in respect to 
criminality, as indicated by convictions for indictable offences. Taking the rates forthe 
Canadian born as a basis, a simple calculation shows that the age distribution of the 
“ Other British” born males is 47 p.c., and of the foreign born males, 53 p.c. more favour- 
able to crime than that of the Canadian born males; and the age distribution of the 
“Other British” born and foreign born females 60 p.c. more favourable than that for 
the Canadian born females. 
The next problem is to determine the importance of differences in sex distribution. 
The numbers of males and females shown in Table A constitute the following proportions 
of the population (both sexes) in respective nativity groups.

If rates for Canadian males and females as given in Tables E and F, be weighted by 
the proportions of males and females in the total Canadian born population, allowance 
would thereby be made for the peculiar sex distribution of that nativity group, and the 
resulting figure would measure the expected number of convictions per 100000 of the
