In spite of the marked diiFerence which there is between Canada 

 and all the other countries, in the distribution of the population aa 

 to ages, there is such a close resemblance between the Censuses of 

 1851 and 1861, as to lead to the inference that we have here a real 

 characteristic of our vital statistics. It can only be very partially 

 owing to immigration, for the State of New York, which is similarly 

 affected in this respect, exhibits a very different law of population. 

 It may be interesting to inquire what effect immigration would have 

 upon the classification by ages. The immigration returns of the 

 United States for the last fifty years, shew that immigrants of all ages 

 arrive in the country, and that there is a great uniformity in the pro- 

 portions at different ages in successive years. Considei-ably more 

 than one-half of any importation would have no sensible effect upon 

 such a table, as it would only add to the total numbers, without dis- 

 turbing the relative proportions ; and of the remaining part, the 

 effect would be in round, numbers, that 10 per cent, of the immigrants 

 ^ould increase the numbers between 15 and 20 ; 25 per cent, those 

 from 20 and 30 ; and 10 per cent, those between 30 and 40. But as 

 the whole annual immigration of late years, even in Upper Canada, 

 has apparently rarely exceeded from 1 to 2 per cent, of the popula- 

 tion, the numbers between 20 and 30, where the effect is the greatest, 

 •would not be very materially altered. When, however, the immigra- 

 tion has continued for many years, what disturbance there was, would
