Answer: The yearly birth rate = 5.24%

Step-by-step explanation:

Birth Rate (or crude birth rate) The number of live births per 1,000 population in a given year.

The population increased from 50000 to 82436 within 10 years

increase = 82436 - 50000

= 32436

Rate = increase ÷ number of years

= 32436/10

=3243.6 per year

Natural increase rates are calculated as a percentage

dividing the result by 1000

3243.6/ 1000

3.24

multiplying the result by 100

3.24%

Natural increase = (birth rate - death rate) X 100

3.24 = BR - 2

BR = 3.24 + 2

BR = 5.24%

The yearly birth rate = 5.24%
