Overall, it can be clearly seen that India showed an upward trend, while China, the USA and Japan followed a downward trend.

In 1950, China dominant the world with its population of 26%, compared to the other three countries. The number of population was decreased, reaching around 24% by 2000, but still it was the highest percentage in that year. It is noticeable that China will continue to drop its population till 2050, and would reach a little under a fifth.
