|
Answer» The three main processes of change of population are—birth rates, death rates and migration. Birth rate:It is the number of live births per thousand persons in a year. It is a maj or component of growth because in India, birth rates have always been higher than the death rates. Death rate:It 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 the death rate. Migration:Migration is the movement of people across regions and territories. Migration can be internal (within the country) or international (between countries). |
