Band 8+: You should spend about 20 minutes on this task. The bar chart shows the percentage of the total world population in 4 countries in 1950 and 2002, and projections for 2050. Summarise the information by selecting and reporting the main features and make comparisons where relevant. You should write at least 150 words.

The given diagram illustrates the ratio of the total population across the globe in India, China, the U.S.A., and Japan. The data are provided from 1950, 2002, and the forecasted 2050. Overall, India has an increasing trend, while the other three countries, on the contrary, have generally decreased. Despite that, India and China are the leaders in this research, while the U.S.A. and Japan are the least.

To begin with, with an index of approximately 22.5% in 1950, China had the largest demography. After a slight drop, India might replace the leader in 2050. According to the chart, China’s population will be considerably lower than India’s in 2050, with about 15% and 18%, respectively. Interestingly, India, at the start of this chart, had the same rate as projected for China’s rate in 2050.

In 1950, the U.S.A. had a population index of about 7% across the world, which is twice as much as Japan had. According to the forecast, the U.S.A.’s percentages remained the same from 2002 to 2050, with just 5% of the total world population. Ultimately, Japan’s population has been decreasing over the entire time period.
