The 2015 revision to the U.N.’s World Population Projections was
released early on Thursday July 30,2015
The world population reached 7.3 billion as
of mid-2015, adding approximately one billion people since 2003
The world population, however, is growing slower now; 10 years ago, the
growth rate was 1.24 per cent a year, while today, it is growing by 1.18
per cent, or approximately, an additional 83 million people annually.
It will take 15 years to add the next billion people, taking the world
population to 8.5 billion in 2030.
By 2050, the world will have 9.7
billion people and 11.2 billion by 2100
The median age of the global population — that is, the age at which half
the population is older and half is younger — is 29.6. About
one-quarter (26 per cent) of the world’s people are under 15 years of
age, 62 per cent are aged 15 to 59, and 12 per cent 60 or above
India is younger than the world; the median age is a full three years
younger and 28.8 per cent are under the age of 15, while just 8.9 per
cent are 60 or over
In seven years, India will surpass China to become the world’s most populous country and will have 1.7 billion residents by 2050
