The bar chart illustrates the proportion of the total world population in four countries (India, China, USA and Japan) in 1950, 2002, and predicted figures for 2050. Overall, the figures for the proportion of world population decreased for all countries except India. Additionally, India is the only country where the proportion of world population is expected to have increased by 2050.
In 1950 and 2002, China made up the greatest proportion of world population, despite a slight decrease in its figures from approximately 23% to 20%. Similarly, the USA and Japan also experienced a decline of around 2% over the same period, with figures at around 5% and 2.5% respectively in 2002. In contrast, the opposite could be seen in India where the figure increased from approximately 15% to 17% in 2002.
In 2050, the figures for China and Japan are predicted to continue to drop to around 15% and 2% respectively, while the figure for the USA is likely to remain unchanged, at 5%. Meanwhile, India’s percentage of world population is projected to continue rising to 19%.
