If a city of population 150,000 experiences 300 births, 220 deaths, 80 emigrants and 50 immigrants in the course of a year, what is its net annual percentage growth rate?

Its net annual percentage growth rate is 0.03

Explanation:

For computing the net annual percentage growth rate, first we have to find out the equation of population change which is calculated below

= (Births + immigrants) - (Death + emigrants)

= (300 + 50) - (220 + 80)

= 350 - 300

= 50

Now, compute the growth rate percentage which is shown below:

= Population change equation : population size * 100

= 50 : 150,000 * 100

= 3.3333 * 100

= 0.03

Hence, its net annual percentage growth rate is 0.03
