Answer:
-14
Step-by-step explanation:
The population growth is defined as an increase in the number of individuals in a population. The growth of a population depends largely on the birth and death rates as well as migration in and out of the population. Mathematically, the population growth can be expressed as:
(B-D) + (I - E), where B = birth rate, D = death rate, I = immigration, and E = emigration.
In the illustration, B = 5, D = 15, I = 2, and E = 4. Therefore;
Population growth = (5 - 15) + (2 - 4) = (-10) + (-4) = -14
Hence, the population growth is -14.
