The charts shows air pollution levels by different causes among four countries in 2021

The bar chart provided compares the proportion of human population in 1950 and 2002 in four countries, and a prediction in 2050.

Apparently, China was the most populated among four nations, whereas Japan had the lowest overall. Meanwhile, India appeared a different trend from other three countries.

Going into more details, in 1950 and 2002, China was the leading nation in terms of population percentage, in 22.5% and 20% respectively. It was predicted that the population ratio will drop 5% by 2050, almost 8% decrease from the highest. A similar trend was also recorded in Japan, but with a smaller change, from about 4% at first, 2.5% in the middle, and projected to be around 1% in 2050.

Although there was a little dwindle in USA from 1950 (7%) to 2002 (5%), the expected ratio remain unchanged in the future. In contrast, India appeared a total different picture that it increased in the two time-point and expected to reach a new high of 19% of the world population.

In summary, despite the huge difference in the population of China and Japan, they had a similar trend of decreasing, where India is expected continue growing in the future years.
