The provided bar chart illustrates the percentage of the world’s total population in four countries – India, China, the USA, and Japan – across three different years: 1950, 2002, and projected for 2050.
Overall, the data shows that China and India consistently hold the largest shares of the global population, while the USA and Japan have much smaller percentages. A notable trend is the projected decline in the population share of all countries except India, which is expected to see a significant increase.
In 1950, China had the highest share at approximately 22.5%, followed by India at 15%. By 2002, China’s share slightly decreased to just below 20%, while India’s rose to about 17%, narrowing the gap between the two. The projections for 2050 indicate a dramatic shift, with India’s share predicted to climb to nearly 20%, surpassing China, which is expected to drop to around 15%.
In contrast, the USA and Japan represent a much smaller portion of the world’s population throughout the period. In 1950, the USA had around 7% of the population, which decreased to approximately 5% in 2002 and is projected to remain at a similar level in 2050. Japan’s share was the smallest of the four, at 4% in 1950, falling to just 2.5% in 2002, with a projected further decrease to less than 1% by 2050.
