Explanation:
Detailed explanation-1: -When the number of births are equal to the number of deaths, the population size is not increasing and the population has reached a stationary phase or plateau phase.
Detailed explanation-2: -During the end of fourth stage, birth and death rates are nearly equal, leading to a period of zero population growth. Thus the overall population begins to plateau.
Detailed explanation-3: -Logic follows then that if the birth rate and death rate are equal, the population is not changing and if the birth rate is less than the death rate, the population would be shrinking (ie. more people are being “taken away” than are being added to the area).
