# Our population which was approximately 350 million at the time of our independence reached close to the billion mark by 2000 and crossed 1 billion in May 2000; this is due to a :

( a ) rapid decline in maternal mortality rate (MMR) and infant mortality rate (IMR)
( b ) rapid decline in death rate
( c ) rapid decline in death rate as well as an increase in number of people in reproducible age
( d ) rapid decline in death rate, maternal mortality rate (MMR) and infant mortality rate (IMR)

Our population which was approximately 350 million at the time of our independence reached close to the billion mark by 2000 and crossed 1 billion in May 2000. That means, every sixth person in the world is an Indian. A rapid decline in death rate, maternal mortality rate (MMR) and infant mortality rate (IMR) as well as an increase in number of people in reproducible age are probable reasons for this.
