The bar chart illustrates the proportion of the global population in four countries — India, China, USA, and Japan — during the years 1950, 2002, and projected for 2050.
Initially in 1950, Japan had the smallest population share at just under 3%, followed by the USA at approximately 10%. Meanwhile, China held the largest share at slightly above 25%, with India close behind at 15%.
By the year 2002, India and China had nearly equal shares of around 20-25%, with a slight edge for China. The USA and Japan maintained similar proportions, both hovering just below 10% and around 5%, respectively.
Looking forward to 2050, India is projected to surpass all previous percentages, becoming the most populous of the four nations. Meanwhile, the USA and Japan are expected to experience declines in their respective shares of the global population.In summary, China consistently held the highest proportion of global population across all three time periods, while Japan showed a decline. India is poised to become increasingly significant in global population share by 2050.
