• B. Birth rate, death rate and migration
• C. Urbanization
• D. None of the above

Answer 1

The correct option is B Birth rate, death rate and migration

The three main processes of change of population: birth rates, death rates and migration. The natural increase in population is the difference between birth rates and death rates.

The 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.

The 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 rapid decline in death rates.

Migration is the movement of people across regions and territories. Migration can be internal (within the country) or international (between the countries).
