Using the vital statistics in Table 1 below:
Total midyear population: 100,000
Population size, 65 years of age or older: 25,000
Number of infants born alive: 3,000
Total deaths (all causes): 1,500
Deaths of infants under 1 year of age: 50
Deaths of persons 65 years of age or over: 1,000
Deaths from heart disease: 300
Deaths from cancer: 100
Table 1
Calculate each of the following:
A. Crude birth rate per 1000:
Crude birth rate per 1000 = (Total Resident Live Births / Total Population X 1,000)
= (3,000 / 100,000) X 1,000
= 30 live births per 1,000 population in that area
B. Crude death rate per 1000:
Crude death rate per 1000 = (Total Resident Deaths / Total Population) X 1,000
= (1,500 / 100,000) X 1,000
= 15 resident deaths per 1,000 population
C. Infant mortality rate per 1000:
Infant Mortality rate per 1000 = (Number of Resident Infant Deaths / Number of Resident Live Births) x 1,000
= (50 / 3,000) X 1,000
= 16.66667 ≈ 17 infant deaths per 1,000 live births
D. The age-specific death rate for people 65 years of age or older, per 1000:
Age-specific death rate for people 65 years of age or older, per 1000 (ASDR) = Individuals dying at a particular age / the population in that age group
= (1,000 / 25,000) X 1,000
= 40 deaths per 1,000 population
E. The cause-specific death rate for heart disease, per 1000:
(300 / 1,500) X 1,000
= 200 deaths from heart disease per 1,000 population
F. The cause-specific death rate for cancer per 1000:
(100 / 1,500) X 1,000
= 66.66 deaths from cancer per 1,000 population
