Short notes on the Construction of Mortality Table

The best method of construction of mortality table will be to select a large number of persons at attained age. Attained age means age nearer to birth date. For example, persons of 19 years 6 months to 20 years 5 months and 29 days will be treated as the age of 20 years. The attained age will be selected at which policy is to begin.

The selected persons of the attained age will be observed and the number of deaths will be recorded during a year till the persons selected are dead. Theoretically speaking this type mortality table will be the actual mortality table.

The number of death in a year is deducted from the number of living at the beginning of year to get the number of living in the beginning of the New Year.

Criticism :

(i) Preparation of such table is difficult because a large number of persons or an attained age is impracticable to get.

(ii) Constant, watch on them is not possible.

(iii) It will require a long-period to construct the table and for which a permanent officer, say for about 100 years, is required.

(iv) A lot of money and time will be wasted to record number of deaths every time.

(v) However, if such impossibilities are dared to do the mortality table will be quite obsolete because it had been constructed at least within 100 years during, which a lot of changes might have occurred.
