Demographic growth


Demographic growth is the increase in the size of a population due to there being more births than deaths (a positive natural balance) and more migrants entering than leaving. 
The population of the world is growing by 2.7 people per second (two people die per second). 95% of this growth is in the less developed world.
Today, approximately one in three people are under fifteen, which has huge implications for future population growth.
