Birth ratesDeath rates andMigration.

Natural increase of population is the difference between birth rates and death rates.

i. Birth rate is the number of live births per thousand persons in a year.

ii. It is a major component of growth in India because birth rates have always been higher than death rates here.

iii. Death rate is the number of deaths per thousand persons in a year.

iv. Main cause of rapid rate of growth of the Indian population is 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.

It resulted in higher rates of population growth.

After 1981, birth rates have also started declining gradually. It has resulted in a gradual decline in the rate of population growth.
