Define Mortality: The following rates are used for measuring mortality.

Crude death rate

The annual crude death rate is defined as 

Crude death rate = annual deaths / annual mean population x 1,000

Specific death rates

The formula for computing specific death rate is:

Number of deaths which occurred among a specific age group of the population of an annual death rate specific for age = given geographic area during a given year / mid- year population of the specified age group in the given geographic area during the same year x 1,000

Illustration:- 
compute the crude and standardized death rates of the two populations A and B from the following data

Age - group (years) A B
  Population          deaths Population          deaths
Below    5 15000                     360 40000                     1000
5 - 30 20000                     400 52000                     1000
Above    30 10000                     280 8000                         240
Total 
45000                   1040 100000                  2280

Solution:-

Crude death rate = N / P x 1000, where N = No. of deaths, P = population

C.D.R for town A = 1,040 / 45,000 x 1,000 = 23.11

C.D.R. for town B = 2,280 / 1, 00,000 x 1,000 = 22.80

Standardized death rate (town A) = (15000 x 24) + (20000 x 20) + (1000 x 28) / 15000 + 2000 + 1000 
                                                             
= 360000 + 400000 + 280000 / 45000 = 1040000 / 45000 = 23.11

Standardized death rate (town B) = (15000 x 25) + (20000 x 20) + (10000 x 30) / 15000 + 20000 + 10000
                                                             
= 375000 + 400000 + 300000 / 45000 = 1075000 / 45000 = 23.89


We can now say that the death rate in town B in higher than in town A.

Another method of computing standardized death rate is to take some assumed population (that is the population of neither town A nor B) as standard, but this method is not so popular
