The demographic transition theory is a generalised description of the changing pattern of mortality, fertility and growth rates as societies move from one demographic regime to another. Characterised by high birth rates, and high fluctuating death rates.
Who gave the theory of the demographic transition?
Frank W. Notestein
In the 1940s and 1950s Frank W. Notestein developed a more formal theory of demographic transition. By 2009, the existence of a negative correlation between fertility and industrial development had become one of the most widely accepted findings in social science.

In this stage, the fertility rate declines and tends to equal the death rate so that the growth rate of population is stationary. As growth gains momentum and people’s level of income increases, their standard of living rises. The leading growth sectors expand and lead to an expansion in output in other sectors through technical transformations.
