The chart illustrates the proportion of the world’s population in four different countries, namely India, China, the USA, and Japan, in 1950 and 2003, with the prediction up to 2050.
Overall, it can be seen that only India experienced an increase from 1950 to 2002, and a projection for 2050, while the remaining nations saw a downward trend. Among these, China recorded the highest figure in both 1950 and 2002. Also, in 2050, India is likely to have the biggest population in 2050. Meanwhile, the figure for Japan was always the lowest in three distinct time periods.
To begin with, India’s population accounted for exactly 15% overall in 1950, marking the second highest figure in that year. This data increased to around 17% in 2002, and it is likely to keep its trend to approximately 18% until 2050. Whilst the percentage of the population in the USA started with around 6% in 1950, it then saw a slight drop to just 5% in 2002; however, this figure may remain stable up to 2050.
In terms of China, despite a small decrease, it still recorded the highest proportion of population in both 1950 and 2002, with around 23% and 20%, respectively. However, this statistic is likely to decline to 15% in 2050, making it the second largest percentage of the population in the world. Ultimately, Japan witnessed the lowest proportion in all three years, starting at approximately 7% in 1950, it then decreased to around 3% in 2002, and it may continue to reduct to just higher than 2% by the end of the timespan.
