Question

Assume that a given country has the following population data. Total midyear population is 90,000,000; male population is 45%; total live birth is 3%; total death is 2%; infant mortality rate is 1%; adult population is 70% and life birth in age group 25-29 is 150,000 and women population in age group 25-29 is 800,000. Based on these data, answer the given questions:

Find crude birth rate (CBR)?
Find crude death rate (CDR)?

Answer 1

To find the crude birth rate (CBR), we use the formula:

CBR = (Number of live births / Total midyear population) x 1000

Given that the total midyear population is 90,000,000 and the total live births is 3% of the total midyear population:

Number of live births = 0.03 * 90,000,000 = 2,700,000

CBR = (2,700,000 / 90,000,000) x 1000 = 30 births per 1000 population

Therefore, the crude birth rate (CBR) is 30.

To find the crude death rate (CDR), we use the formula:

CDR = (Number of deaths / Total midyear population) x 1000

Given that the total midyear population is 90,000,000 and the total deaths is 2% of the total midyear population:

Number of deaths = 0.02 * 90,000,000 = 1,800,000

CDR = (1,800,000 / 90,000,000) x 1000 = 20 deaths per 1000 population

Therefore, the crude death rate (CDR) is 20.
