in the United States in Fifty Years.

population is supposed likely to continue as it has been, or with 

 such small changes as will not materially vary the result. But the 

 future condition of that part of our population will be separately 

 considered in the next chapter. 



Some of our readers, who may wish to make calculations con- 

 cerning the past or future increase of the population, may find a 

 convenience in the following 



Table shoimng, in different rates of Decennial Increase, the corresponding rates for the 

 intermediate years, and the number of years necessary for the Population to double, 

 at different rates of Increase. 



According to the preceding table, the population on the 1st m 

 the present year, or three years after the census was last taken,/is 

 as follows : 



The increase on the last decennial term was 32.67 per cent, afid 

 the rate of increase for three years, in the table, being 8.68 per 

 cent, where the decennial increase is 32 per cent, and 8.93 per 

 cent where the decennial increase is 33 per cent, the intermediate 

 rate of incfrease or three years, now, is 8.85 per cent. This gives 

 an increase of 1,510,646, which, added to 17,069,453, shows the 

 whole population of the United States to have been, on the 1st of 

 June last, 18,580,000. In the latter year of the current decenniaji 

 term, a small deduction must be made for the gradual diminution 

 in the rate of increase.
