418 Ml'. Lubbock on the Census. 



In these calculations I supposed the rate of increase to be 

 uniform ; but I repealed similar calculations with the rate of 

 increase of the baptisms (which may be considered the same 

 as that of the births) as given in each year, by the Report be- 

 fore alluded to, and I found from the table of mortality, de- 

 duced from the Chester observations, the ratio of the deaths 



to the population = „ ^ or '0271 : if we suppose the rate of 



hicrease to be r0167, this gives •0438 for the ratio of the 



births to the population, or -^.^^ "early ; and I constructed 



the following Table, which offers a comparison of the propor- 

 tions which the number of persons at different ages, as given 

 by the census and by theory, bears to the population. 



The result of theory agrees pretty well with observation. 

 It may be observed that the age from 20 to 30 appears de- 

 cidedly the favourite with females ; for while the error of 

 theory between 30 and 4-0 is only + "00005, the error between 

 20 and 30 is — "00193; the error for males at the same epoch 

 is + -00039. 



Considering the limits of the errors of which these calcula- 

 tions are susceptible, I do not think the ratio of the deaths to 

 the population can differ much from -^j or "027; if, therefore, 

 we take the census to be correct, and that 11,201,437 was the 

 number of the population in 1821, we have for the deaths in 

 1821,304,350, instead of 201,410, making the unentered bu- 

 rials amount to 102,940, or nearly a third of the total number. 



Some writers, and particularly Dr. Hawkins in his valuable 

 work on medical statistics, have inferred from the small pro- 

 portion of the deaths to the population given by the parlia- 

 mentary report, and from its being so much less than what ob- 

 tains
