Question 2.
Answer the following questions briefly.
(i) Why is the rate of population growth in India declining since 1981?
(ii) Discuss the major components of population growth.
(iii) Define age structure, death rate and birth rate.
(iv) How is migration a determinant factor of population change?
Answer:
(i) Since 1981, the rate of population growth started declining gradually due to a reduction in the birth rates. This has been due to the efforts at birth control.
(ii) The major components of population growth are:

  • 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 larger than death rates.
  • Death rate is the number of deaths per thousand persons in a year. The main cause of the rate of growth of the population has been the rapid decline in death rates.
  • Migration is the movement of people across regions and territories. Migration can be internal or international.

(iii) Age Structure refers to the number of people in different age groups in a country. The population of a nation is divided into three categories:

  • Children (below 15 years)
  • Adults/working population (15-59 years)
  • Aged (above 60 years)

Death rate: It is the number of deaths per thousand persons in a year.
Birth rate: It is the number of births per thousand persons in a year.

(iv) Migration is the movement of people across regions and territories. It not only changes the population size but also the population composition of urban and rural populations in terms of age and sex composition. In India, the rural-urban migration has resulted in a steady increase in the percentage of population in cities and towns. Thus, migration plays a very significant role in changing the composition and distribution of population.

Developed nations have a high proportion of people in secondary and tertiary activities. Developing countries have a higher proportion of the workforce engaged in primary activities. In India there has been a shift in favour of secondary and tertiary sectors because of growing industrialisation and urbanisation.
