The bar chart depicts the total percentage of the world population in four countries. The data provides the period in 1950 and 2002, also projections for 2050.
Overall, China initially dominated the proportion, although it declined, while the USA and Japan mirrored this trend with smaller proportions. Conversely, India increased over the period, exceeding China’s population.
In 1950, China’s population reached the highest percentage of the total world population, commencing at almost 25%, declining to 20% in 2002, and projected to keep declining to 15% in 2050. Similarly, Japan’s population decreased from a tiny fraction of around 4% to the lowest proportion of 1% in its projection for 2050. However, the USA commenced at approximately 7% in 1950, slightly declined, and is predicted to remain stable at 5% until 2050. In contrast, India steadily rose, beginning at 15% in 1950 to around 17% in 2002, and is predicted to keep climbing to nearly 20% of the total world population in 2050.
