Answer:
Its net annual percentage growth rate is 0.03
Step-by-step 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
