USE AND CONSTRUCTION OF TABLES.
Table I. shows out of a certain number born how many live to attain
each year of age, and forms the basis of every description of calculation
connected with the subject of Life Contingencies.
Table II. shows the expectation of life deduced from the various rates
of mortality, or, in other words, the average number of years that one
individual taken with another may expect to enjoy at the different ages
of existence.
Table III. is similar in description to Table I.
In Table V. the first column shows the proportion to unity that die
at each year of age, and is formed by dividing the number in Table I.,
in the column of decrements, by the number at the same age in the
column of the number of living: the second column is found by sub
tracting from unity the quantity in the first column; and the third column
is obtained by dividing unity by the number in the second column, or
by dividing the number in the column of living, at any given age, by
the number in the same column at the next older age. At the age of
72
20, ———- = .014030 the number in the first column, 1—.014030=

. 985070 the number in the second column, and —-—-— or s=

1.01432, the number in the third column.
In Table VI. the number at any age in column D is found by mul
tiplying the present value of ¿Cl due at the end of as many years as the
age by the number of persons, according to the table, living at that age.
In Table IV., Part I., at 3 per cent, the present value of £l, due at
the end of 30 years, is .41198676; and by Table I., Part II., the
number living at the age of 30, by the Northampton table of mortality,
is 4385 • the product of the two is the number in the table in column D,
viz., 1806.562.
Column N is formed by taking the number in column D, at the oldest
age in the table, and adding to it the number of the oldest age but one,
then to this sum adding the number at the oldest age but two, and so
on throughout the table.
