The world population currently stands at over 7.7 Billion people in the year 2019(1^✔). Medindia’s dynamic world population clock uses the crude birth and death rate of the world for its calculation. The current crude birth rate of the world is 18.9 per 1000 population and death rate is 7.5 per 1000 population(2^✔).

The world population is growing rapidly at an exponential rate. It took the world 200,000 years to reach one billion mark but only took just 200 years to hit the seven billion mark(3^✔). The one billion mark was reached around 1804 and in just over 100 year (1927) the population had reached the 2 billion mark. After this the population growth was even faster and the last billion just took 12 years(4^✔).

India and China together contribute to almost 40% of the world’s population(5^✔). This means that 4 out of 10 people in the world come from India or China.

In our existence for the last 52,000 years on this planet Earth, there have been a total of about 106 billion people. Every year we add almost 78 million people to the world population and this is rapidly consuming the world's resources.

By 2025, it is predicted we will be more than 8 billion and likely to reach around 9 billion by 2037. British Physicist, J. H. Fremlin estimated this alarming rise and predicted our current growth as follows-

'At the current rate it would take only about 50 years to populate Venus, Mercury, Mars, the moon, and the moons of Jupiter and Saturn to same population density as Earth. . . It would take only about 200 years to fill [the remaining planets] "Earth-full." . . . What then? .' - J. H. Fremlin

QUOTES ON POPULATION:

“The problem is that the population is growing the fastest where people are less able to deal with it. So it’s in the very poorest places that you’re going to have a tripling in population by 2050. And we’ve got to make sure that we help out with the tools now so that they don’t have an impossible situation later.” - Bill Gates

“Basically, then, there are only two kinds of solutions to the population problem. One is a ‘birth rate solution,’ in which we find ways to lower the birth rate. The other is a ‘death rate solution,’ in which ways to raise the death rate — war, famine, pestilence — find us.” - Paul Ehrlich-
