You are studying the population of an isolated city in Montana. In 2000, the population size was exactly 50,000. In 2010, the population size had grown to an astonishing 82,436. There was no migration into or out of the town. You know from surveying the cemeteries that the death rate was roughly 2% per year. What was the yearly birth rate

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%
