Explain the Demographic Transition Theory?
Theory of Demographic Transition may be a theory that throws lightweight on changes in birth rate and death rate and, consequently, population growth rate. In connection with economic development, tendencies of birth-rate and death rate are different.
First Stage:
This stage is known as the high increase potential stage. It defines by high and unsteady birth and death rates which can neutralize one another virtually. Individuals largely board rural areas, and their main occupation is agriculture within the stage of sub normality. The tertiary sector consisting of transport, commercial banking, and insurance is underdeveloped.
As a result, they're malady-ridden, and therefore the absence of correct treatment ends up in massive deaths. The morbidity is highest among the poor. Thus, high birth rates and death rates stay or so equal over time so that a static equilibrium with zero increase prevails.
Second Stage:
It is known as the stage of Population Explosion. During this stage, the death rate decreases, whereas the birth rate remains constant at a high level. Agricultural and industrial production will increase, suggests that transport and communication develop. There's the excellent quality of labor. Education expands. Financial gain additionally will increase. Individuals get an additional and higher quality of food merchandise. Medical and health facilities dilate.
During this stage, economic development sped up thanks to individual and government efforts. Accumulated use of higher technology, mechanization, and urbanization takes place. However, there are no substantial modifications within the men, a perspective of the individuals and thence birth rate stays high, i.e., economic development has not started moving the birth rate.
Third Stage:
It also defines as a population stage as a result of the population continuing to grow at a quick rate. During this stage, the birth rate as compared to the death rate declines sooner. As a result, the population grows at a decreasing rate. This stage witnesses a fall within the birth rate, whereas the death rate stays constant due to it already declined to the bottom minimum. The birth rate declines thanks to the impact of economic development, modified social attitudes, and accumulated facilities for planning. The population continues to overgrow due to the death rate stops falling, whereas the birth rate though declining, remains on top of a death rate.
