Human population represents a logistic growth curve.


Please go through the following equations:

When rate of natural increase i.e. (b-d)= r is constant then a population growth curve is exponential. In case of human population assuming that this remains unchanged is entirely false.

Value of (b-d)=r reached its peak in 1990s, and has shown a declining trend since then. Hence, human population growth curve has already shown logistic tendency.

Increased use of birth control measures by women in developing countries could be the most important reason behind this decline. Despite the fact that indefinite exponential growth can not continue, world population will continue to grow till 2050.
