Answer 1

The population growth pattern in India over the last one century has been induced by the annual birth rate and death rate and migration rate, indicating various patterns.

Complete answer:
Population growth is a change in the size of the population in a geographic region between two periods in time. Its rate is calculated in percentage. Population growth has two components: natural and induced. While natural growth is evaluated by measuring the blunt birth rate and death rate, the induced components are described by the amount of inward and outward movement of people in any given area.

The years from 1951-1981 were referred to as the time of population explosion in India, caused by a gradual decrease in the death rate but a high population fertility rate in India. It is in this period, following independence, that development activities have been implemented through a centralised planning mechanism, and the economy has begun to demonstrate the improvement of people's living conditions in general. As a result, there was a naturally high increased rate of growth in population. While the growth rate of the country's population remained high in the post-1981 period, it has begun to slow down steadily. The downward trend of the birth rate is believed to be responsible for such population growth. This in turn, was influenced by an increase in the average age of marriage, an improvement in the quality of life, especially of the education of women in the country.

Hence, the correct answer is option (D)

Note: The decadal and annual population growth rates in India are both very high and growing steadily. The average growth rate of the population of India is 1.64 per cent (2011).
