despite the decline in growth rates, the number of people being added every decade is steadily increasing, why??
1) Growth rate of population declined in India since 1981 due to decline in birth rates and it is considered as positive indicator of birth control
2) At the same time, India’s population is added every decade, for instance, 182 million people were added to total population in 1990
3) This may be due to improved health and sanitation facilities and as a result, death rate has been declined considerably.
4) Apart from death rate reduction, migration also plays a significant role in changing the composition of population
