The population started to increase rapidly since the middle of 17th century. We can find that the population of Europe, Russia and America was increased rapidly before 1950 AD. This speed of population growth was found in China in about 1700 AD. Population expert Colin Clark expected that the world population would reach 3.5 Arab in 1900 AD. Next Population expert Notestine expected that the world population would reach 3.3 Arab in 2000 AD. But that expected population exceeded before 2000 AD. Similarly, the world’s population reached 6 Arab in 1999 AD. There was an increment of 1 Arab population in the world in a short duration of 12 years.
