To calculate the population growth, we can use the formula:
Population Growth = (Birth Rate – Death Rate) + (Immigration – Emigration)
Plugging in the values from your question:
– Birth Rate = 5
– Death Rate = 15
– Immigration = 2
– Emigration = 4
Now we calculate:
Population Growth = (5 – 15) + (2 – 4)
Population Growth = (-10) + (-2)
Population Growth = -12
The correct answer is B. -12. This means the population is decreasing by 12.
