A little over a decade ago, the world’s population stood at 6billion. By the end of October, it will reach 7billion.
With five babies being born every second, 78million people are added to the global community each year.
The population was fewer than 1billion in 1800, 3billion in 1960 and 6billion as recently as 1999.
