Phases of Population Growth
There are four different phases of population growth:
- Phase-I (1901-1921): stagnant or stationary phase because of very low growth rate. Reasons for high birth and death rates were poor health and medical services, illiteracy of people and inefficient distribution of food and basic necessities.
- Phase-II (1921-1951): period of steady population growth. In India, there was an overall improvement in health and sanitation during this phase.
- Phase-III (1951-1981): This period is known as the period of population explosion in India. Rapid fall in death rate and high fertility rate were the main causes of this explosion.
- Phase-IV (Post 1981 till present): Growth rate has started down gradually because of downward trend in birth rate. But in developing countries like India, growth rate is still high.
The World Development Report says that by 2025, the Indian population will surpass the figure of 1350 million.
