Question 2.
Write brief answers:
(i) Why is the rate of population growth in India declining since 1981?
Answer:
Since 1981, the rate of growth started declining gradually. The declining trend of the growth rate is mainly due to the efforts done with regard to birth control: I
(ii) Discuss the major components of population growth.
Answer:
The major components of population growth are as under:
1. Birth rate is the number of live births per thousand persons in a year. It is a major component of growth because in India, birth rates have always been higher than death rates.
2. Death Rate is the number of deaths per thousand persons in a year. The main cause of the rate of growth of the Indian population has been the fast decline in death rates.
Till 1980, high birth rates and declining death rates led to a large difference between birth rates and death rates resulting in higher rates of population growth. Since 1981, birth rates have also started declining gradually, resulting in a gradual decline ini the rate of population growth. What are the reasons for this trend?
3. Migration: The third component of population growth is migration. Migration is the movement of people across regions i and territories. Migration can.be internal (within the country) or international (between countries).
Internal migration does not change the size of the population, bujt influences the distribution of population within the nation. Migration plays a very significant role in changing the composition and distribution of population.
In India, most migrations have been from rural to urban areas because of the “push” of the adverse conditions of poverty and unemployment in the rural areas and the “pull” of the city in terms of increased employment opportunities and better living conditions. ‘
(iii) Define age structure, death rate and birth rate.
Answer:
Age structure refers to the classification of population into:
(a) children, (b) adult, (c) aged.
Death rate is the number of deaths per thousand persons in a year.
Birth rate is the number of live births per thousand persons in a. year.
(iv) How is migration a determinant of population change?
Answer:
Migrations are an important determinant of population change. They change not only the population size but also the population composition in terms of urban and rural populations and in terms of age and sex composition. In India, the rural-urban migration has resulted in a stayed increase in the percentage of population in cities and towns. The urban population has increased from 17.29 per cent of the total population in 1951 to 27.78 percent in 2001. There has been a significant increase in the number of ‘million plus cities’ from 23 to 35 in just one decade 1991-2001.
Question 3.
