World Population Clock

The world population on Jan.1, 2024 was projected as 8.01 Billion an increase of 75.16 million from 1^st Jan 2023().

Medindia’s world population clock displays simulated real-time growth of the world population. This is based on the calculation of a birth rate of 4.3 and a death rate of 2.0 every second. The current crude birth rate of the world is 18.5 per 1000 population and the death rate is 7.8 per 1000 population().

The world population in the last 200 years has grown rapidly at an exponential rate. It took the world 200,000 years to reach the one billion mark but it only took 200 years to hit the eight billion mark(). The one billion mark was reached around 1804 and in just over 100 years (1927) the population had reached the 2 billion mark. After this, the population growth was even faster and it just took 12 years to jump from 6 to 7 billion ( from 1999 to 2011) and 11 years to cross from 7 to 8 billion (15^th Nov 2022) ().

Paul Ehrlich said that 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.”

Our Fragile Earth

Our earth is about 4.55 billion years old with a total surface area of 510.072 million sq km of which 148.94 million sq km is land and 361.132 million sq.km (almost 70%) of the surface is covered with water. It has limited resources and a fragile environment. The human population explosion and the exploitation of earth’s resource in the last 200 years has resulted in rapid depletion of its resources and is causing global warming.

Currently every year 83 million people are added but only 60 to 61 million people die. At this rate, we will double the world population every 50 to 60 years or even sooner.

“The problem is that the population is growing the fastest and 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

In the human existence for the last 52,000 years on this planet, there have been a total of about 106 billion people. By 2037 we are likely to reach around 9 billion. 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
