Not illustrated. 1838 Excerpt: ...equally true that the notorious individual uncertainty of life cannot be discovered in the results of observations made upon masses of individuals. There are various results of observation, which are called tables of mortality, which differ only in the methods of presenting the same sets of facts. Firstly, we have what may be called tables of the numbers living. These show, for a given number born, how many attain each year of age. Thus, in the Carlisle table, opposite to 0 and 50, we find 10,000 and 4397, indicating that, according to observations made at Carlisle, the proportion of those born to those who saw their fiftieth birthday, was that of 10,000 to 4397-Again, opposite to 60, we find 3643, meaning, that of 4397 persons aged 50, 3643 attain the age of 60.

Thirdly, we have tables of mean duration of life (commonly called expectation of life), which show the average M number of years enjoyed by individuals of every age. This, in another variety of the Carlisle tables, opposite to 50 and 60, we find 21-11 and 14-34; meaning that, according to these tables, persons aged fifty live, one with another, 21-11 years more, and persons aged 60, 14-34 years more. Until observations of human mortality become more extensive and correct, I prefer the tables of mea...
